BK PRECISION 917008000 Isolated Logic Channel Module

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..).

Figure 1.1: General presentation
Overview

  • 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.

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.

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.
