Product Usage Instructions

Mounting/Installation
The TT521 can be mounted on a DIN rail in safe areas or hazardous gas and dust areas. For DIN form B sensor head mounting in non-hazardous areas, the TT521 can be mounted on a DIN rail using the AC807 Minco DIN rail adapter.

RTD Measurement
The TT521 supports linearized temperature measurement with RTD sensors, such as Pt100 and Ni100. To measure temperature using an RTD sensor, follow these steps:

Connect the RTD sensor to the RTD input terminals of the TT521.
Ensure the RTD sensor type matches one of the supported types (e.g., Pt100, Ni100).
Configure the desired temperature units and calibration settings through the device’s HART communication interface.
The TT521 will convert the RTD sensor’s resistance variation into a standard 4-20mA current signal, which can be used for temperature measurement.

Thermocouple Measurement
The TT521 also supports temperature measurement using thermocouples. To measure temperature using a thermocouple, follow these steps:

Connect the thermocouple to the TC input terminals of the TT521.
Ensure the thermocouple type matches one of the supported types (e.g., B, E, J, K, T, etc.).
Configure the desired temperature units and calibration settings through the device’s HART communication interface.
The TT521 will convert the thermocouple’s voltage output into a standard 4-20mA current signal, which can be used for temperature measurement.

Linear Resistance Measurement
The TT521 can convert linear resistance variation to a standard 4-20mA current signal. This feature is useful for measuring variables such as valve positions or Ohmic level sensors. To measure linear resistance, follow these steps:

Connect the linear resistance source to the input terminals of the TT521.
Configure the desired calibration settings through the device’s HART communication interface.
The TT521 will convert the linear resistance variation into a standard 4-20mA current signal, which can be used for measurement.

mV Signal Amplification
The TT521 can amplify a bipolar mV signal to a standard 4-20mA current signal. To amplify an mV signal, follow these steps:

Connect the mV signal source to the input terminals of the TT521.
Configure the desired calibration settings through the device’s HART communication interface.
The TT521 will amplify the mV signal and convert it into a standard 4-20mA current signal.

HART Communication
The TT521 supports HART communication, allowing for advanced configuration and monitoring of the device. To utilize HART communication, follow these steps:

Connect the TT521 to a HART-enabled communication interface, such as AC208517.
Use compatible HART software or equipment to establish communication with the TT521.
Through the HART interface, configure various device parameters, such as calibration settings, variable mapping, and event notifications.
Monitor and retrieve data from the TT521 using the HART interface.

MINCO-TT521-2-Wire-Programmable-Transmitter-fig-12

HART Communicator
For programming please refer to the drawing below. To gain access to product‐specific commands, a suitable HART communicator must be loaded with the PR electronics A/S DDL driver. This can be ordered either at the HART Communication Foundation or at PR electronics A/S.

Collection of Transmitters in Multidrop Mode
The HART communicator of a PC Modem can be connected across AB or BC.

MINCO-TT521-2-Wire-Programmable-Transmitter-fig-14

The outputs of maximum 63 transmitters can be connected in parallel for a digital HART 7 communication on 2‐wires.
Before it is connected, each transmitter must be configured with a unique number from 1 to 63. If 2 transmitters are configured with the same number, both will be excluded.
The transmitters must be programmed for multidrop mode (with a fixed output signal of 4 mA). Maximum current in the loop is therefore 252 mA.
The communication is either by means of HART communicator or a HART modem.
The Temptran Utilities configuration software can configure the individual transmitter for multidrop mode and provide it with a unique polling address.

The entity concept

The Transmitter must be installed according to National Electrical Code (ANSI‐NFPA 70) and shall be installed with the enclosure, mounting, and spacing segregation requirement of the ultimate application.
Equipment that is FM‐approved for intrinsic safety may be connected to barriers based on the ENTITY CONCEPT. This concept permits interconnection of approved transmitters, meters and other devices in combinations which have not been specifically examined by FM, provided that the agency’s criteria are met. The combination is then intrinsically safe, if the entity concept is acceptable to the authority having jurisdiction over the installation.
The entity concept criteria are as follows:
- The intrinsically safe devices, other than barriers, must not be a source of power. The maximum voltage Ui(VMAX) and current Ii(IMAX), and maximum power Pi(Pmax), which the device can receive and remain intrinsically safe, must be equal to or greater than the voltage (Uo or VOC or Vt) and current (Io or ISC or It) and the power Po which can be delivered by the barrier.
- The sum of the maximum unprotected capacitance (Ci) for each intrinsically device and the interconnecting wiring must be less than the capacitance (Ca) which can be safely connected to the barrier.
The sum of the maximum unprotected inductance (Li) for each intrinsically device and the interconnecting wiring must be less than the inductance (La) which can be safely connected to the barrier.
The entity parameters Uo,VOC or Vt and Io,ISC or It, and Ca and La for barriers are provided by the barrier manufacturer.
