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..).

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.

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

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.
