BK PRECISION 917008000 Isolated Logic Channel Module User Manual

Presentation

• The isolated channel module is an accessory only compatible with the SEFRAM Data Acquisition Systems: DAS220-240 / DAS30-50-60 / DAS1700-8460.
• This module allows the 16 logic channels (inputs / outputs) present on the DAS range to be deported via the Sub-D 25 connector. Equipped with optocouplers, it allows to increase the voltage input capacity of the logic channels (normally limited to 24V without this accessory), while bringing a comfort for the wiring on your equipments.
• The applications are multiple, such as the monitoring of logical state changes in an electrical cabinet (electrical relays, contacts..).

• Screw connector 3C (x12): see chapter 2.1 for use

• Screw connector 3C (x12): see chapter 2.2 for use

These accessories can be provided as spare parts with the kit 984405600

Use

Logic channels inputs

First of all you have to connect the D-sub 25 wires cable between the isolated channel module and the DAS (4). Then choose the input on which to connect your signal according to the voltage allowed:

• 90V to 250V DC or AC between red and black socket (1)
• 10V to 48V DC or AC between pins 1 and 3 of the green terminal block (2)
• Below 10V DC or AC between pin 1 and 2 of the green terminal block (3)

All inputs are isolated from each other and from ground.

Figure 2.1: Maximal voltage input allowed

Power supplies and alarms outputs

The 10-contact terminal block is not isolated. The grounds are connected together. It allows 3,3V, 5V or 12V voltage supplies of an external circuit (sensor or other) or to output the TTL 0-5V signals (alarms) of the Data Acquisition System. The maximum current output is 200 mA.

The different pins are arranged as follows:

Conditions

Warranty

Your instrument is warranted for two years against defects in materials and workmanship. This warranty applies from the date of delivery and ends 730 calendar days later. If the unit is covered by a warranty agreement, the warranty agreement supplements, supersedes, or replaces the warranty terms listed above. The warranty
conditions applicable by SEFRAM are available on the website www.sefram.com.
The terms and conditions of this warranty take precedence over this summary. This warranty does not cover defects resulting from abnormal use, handling errors or storage conditions outside the defined range. In the event of a warranty claim, the user must return the device concerned to our factory at his own expense :

SEFRAM Instruments SAS Service Après-vente 32, Rue Edouard MARTEL BP 55 42009 SAINT-ETIENNE CEDEX 2 and write a a description of the fault found with the equipment.The accessories delivered as standard with the device (cords, plugs…) are guaranteed for 3 months against manufacturing defects. Wear and tear, accidental breakage or breakage resulting from a shock or abnormal use are not guaranteed. The time remaining to be covered if the device is guaranteed – If the warranty of the device < 90 days, the replaced part is guaranteed 90 days
Any replacement part becomes the property of the user and the exchanged parts become the property of SEFRAM. In case of insurance coverage, the product becomes the property of the latter at its exclusive request. Otherwise it remains the property of the user. The warranty applies only to equipment manufactured and supplied by SEFRAM. Any intervention or modification made by the user or by a third party without prior authorization from the company will result in the loss of the benefit of the warranty. The user is responsible for the return of the equipment to our premises. He must therefore ensure that the packaging will allow proper protection during transport. He must take out the necessary insurance for the transport at his own expense. SEFRAM reserves the right to refuse a poorly packed product, and not to propose a repair if the breakage is due to transport.

Metrology

You are in possession of a measuring instrument for which the metrological conditions are defined in the specifications of this manual. The climatic and environmental conditions limit the specifications of your Instrument. SEFRAM checks the characteristics of each instrument individually on an automatic rack during its manufacture. Adjustment and verification are guaranteed within the framework of ISO9001 certification by measuring instruments connected to COFRAC (or equivalent in ILAC reciprocity). When a product returns to SEFRAM, a maximum service is ensured with internal upgrading according to the necessary evolutions and software upgrading. In case of deviation from the specifications, your instrument will be adjusted to its original characteristics.

Packaging

The packaging of this product is entirely recyclable. It is designed to transport your instrument in the best conditions. We draw your attention to the fact that the original packaging must be over-packed if it is used for transport by air, road or mail. We recommend that you keep the original packaging for any transport.
