BEKA BA3301 Pageant Analogue Input Module
Product Information
The BA3301 Pageant Analogue Input Module is a plug-in module that features four galvanically isolated unpowered 4/20mA passive inputs. It is designed to be safely plugged into any one of the seven slots on a Pageant BA3101 Operator Display. The module has separate IECEx, ATEX, and UKCA intrinsic safety apparatus certification, allowing it to be used in various gas or dust atmospheres. The output safety parameters of each input are zero, and the module has a low input voltage drop.
The BA3301 module is CE marked to comply with the European Explosive Atmospheres Directive 2014/34/EU and the European EMC Directive 2014/30/EU. It is also UKCA marked to comply with UK statutory requirements.
Product Usage Instructions
- Ensure that the BA3301 module is used as part of a BEKA Pageant System.
- For hazardous area installations, the plug-in module must be manufactured by BEKA and have certification specifying its use as part of a BEKA Pageant system.
- To install the BA3301 module, fit it into one of the seven sockets at the rear of a BA3101 Pageant Operator Panel, as shown in Fig 2.
- Check the power limitations for the BA3301 plugin module before installation.
- Refer to the certification information label on the side of the module for model number, certification information, BEKA associates address, year of manufacture, and serial number.
INTRODUCTION
The BA3301 plug-in analogue input module has four galvanically isolated
unpowered 4/20mA passive inputs. Separate IECEx, ATEX and UKCA intrinsic
safety apparatus certification allows it to be safely plugged into any one of
the seven slots on a Pageant BA3101 Operator Display.
The output safety parameters of each input are zero which, together with the
low input voltage drop, allow connection in series with almost any
intrinsically safe 4/20mA loop in any gas or dust atmosphere.
INTRINSIC SAFETY CERTIFICATION
Notified Body CML B.V. and UK Approved Body Eurofins CML have issued plug-in BA3301 Pageant Analogue Input modules with the following apparatus certificates:
- IECEx IECEx CML 21.0101X
- ATEX CML 21ATEX2830X
- UKCA CML 21UKEX2831X
Fig 1 BA3301 Pageant Analogue Input module 4 x 4/20mA
The ATEX certificate has been used to confirm compliance with the European
ATEX Directive for Group II, Category 1GD equipment, similarly the UKCA
certificate has been used to confirm compliance with UK statutory
requirements. All BA3301 modules carry both the CE and UKCA marks therefore,
subject to local codes of practice, they may be installed in any of the
European Economic Area (EEA) member countries and in the UK. ATEX certificates
are also acceptable for installations in some non EU countries.
These instructions describe IECEx, UKCA and ATEX installations which conform
with IEC / EN 60079-14 Electrical installations design, selection and
erection. When designing systems the local code of practice should be
consulted.
Zones, gas groups and T rating
All of the BA3301 certificates specify the same certification codes and safety
parameters:
-
Ex ia IIC T4 Ga
-
Ex ia IIIC T135°C Da* -40°C ≤ Ta ≤ 65°C
-
Dust certification requires the Pageant Operator Display and the BA3301 module to have a minimum additional IP54 rear protection – see 2.2 ii below.
Special conditions for safe use
- Under certain extreme circumstances, the nonmetallic parts incorporated in the enclosure of this equipment may generate an ignition-capable level of electrostatic charge. Therefore, the equipment shall not be installed in a location where the external conditions are conducive to the build-up of electrostatic charge on such surfaces. In addition, the equipment shall only be cleaned with a damp cloth.
- In installations requiring EPL Da, Db, or Dc, the equipment shall be mounted to an enclosure which provides a minimum degree of protection of IP5X and which meets the requirements of EN60079-0 Clause 8.4 (material composition requirements for metallic enclosures for Group III) and/or EN60079-0 Clause 7.4.3 (Avoidance of a build up of electrostatic charge for Group III) as appropriate. All cable entries into the equipment shall be made via cable glands which provided a minimum degree of protection of IP5X.
- The BA3301 shall only be used as part of a BEKA Pageant System.
Plug-in BA3301 Pageant Analogue Input Modules are CE marked to show compliance
with the European Explosive Atmospheres Directive 2014/34/EU and the European
EMC Directive 2014/30/EU.
The modules are also UKCA marked to show compliance with UK statutory
requirements Equipment and Protective Systems Intended for Use in Potentially
Explosive Atmospheres Regulations UKSI 2016:1107 (as amended) and with the
Electromagnetic Compatibility Regulations UKSI 2016:1091.
Certification label information
The certification information label is fitted to the side of the plug-in
BA3301 module. It shows the model number, certification information, BEKA
associates address and year of manufacture together with the serial
number.
INSTALLATION
The BA3301 plug-in module should be fitted into one of the seven sockets at
the rear of a BA3101 Pageant Operator Panel as shown in Fig 2.
For a hazardous area installation the plug-in module must be manufactured by
BEKA and have certification that specifies that it shall be used as part of a
BEKA Pageant system.
Power consumption
The intrinsic safety certification of the BA3301 plug-in module permits any
combination to be installed in a Pageant BA3101 display, but there are power
limitations.
The percentage of the total available power that the BA3301 consumes is:
BA3301 4 x 4/2mA inputs : 4%
The sum of the percentage power consumption’s of all the plug-in modules installed in a BA3101 display must not exceed 100%.
Plug-in BA3301 module Installation
- The module may be fitted before or after the Operator Display is installed. The Operator Display should not be powered while the module is being fitted or removed.
- Carefully insert the module into the selected slot at the rear of the BA3101 Pageant Operator Display. When correctly positioned secure the module by tightening the two captive module fixing screws.
- Connect field wiring to each of the four removable input terminal blocks. All the inputs are identical as shown in Fig 3. Each of the four inputs is a separate intrinsically safe circuit and field wiring should comply with segregation requirements specified in IEC/EN 60079-14. If a multicore cable is used for the inputs, it should have Type A or B construction as specified in Clause 16.2.2.7 of IEC/EN 60079-14 Wiring should be supported to avoid damaging the module’s terminals.
INPUTS
The Pageant BA3301 module has four galvanically isolated unpowered 4/20mA passive inputs. Each input is certified as a separate intrinsically safe circuit with the following safety code and parameters.
- Ex ia IIC T4 Ga
- Ex ia IIIC T135°C Da -40°C ≤ Ta ≤ +65°C
- Ui = 30V
- Ii = 200mA
- Pi = 0.84W
- Uo = 0
- Io = 0
- Po = 0
- Ci = 0
- Li = 4μH
The output safety parameter of each input are zero which, together with the low input voltage drop, allow connection in series with almost any intrinsically safe 4/20mA loop in any gas or dust in Zone 0, 1, 2, 20, 21 or 22.
Loop powered 4/20mA transmitters
Loop powered transmitters should be powered from a galvanic isolator or Zener
barrier with output safety parameters compatible with the transmitter’s and
the BA3301’s intrinsic safety input parameters. The output parameters of each
BA3301 4/20mA loop are zero and the internal inductance is very small and can
be ignored when determining the loops safety.
Terminals 2 and 4 of each BA3301 input are internally linked for joining the
return 4/20mA wire as shown in Fig 4.
Separately and self powered 4/20mA transmitters
Separately powered transmitters and instruments with a 4/20mA output can be
directly connected to a BA3301 input as shown in Fig 5.
MAINTENANCE
A BA3301 4/20mA input module should be regularly inspected to ensure that it
has not been damaged. The frequency of inspection depends upon environmental
conditions.
No attempt should be made to repair a faulty plug-in module. Suspect modules
should be returned to BEKA associates or your local BEKA agent.
GUARANTEE
Modules which fail within the guarantee period should be returned to BEKA associates or your local BEKA agent. It is helpful if a brief description of the fault symptoms is provided.
