BIG-K-2I-1/22 Intrinsic Safety Barrier Discrete Input
Product Description
Has two relay outputs for connection to a control system in a safe area.
Advantages
- Input, output and power supply signals are galvanically isolated from each other.
- The electronic circuits of the barriers are coated with varnish, which additionally protects the elements from external factors.
- Mounting on the BIG-BAZA or MTL4500 backplane.
- Speed and ease of installation.
- Availability of LED indication.
- Configurable via DIP switch.

| If the output load resistance is less than 80 ohms, the device detects this condition as an output short circuit. If the output load resistance exceeds 6000 ohms, the device detects this condition as an open circuit. In the event of a fault, the input current is limited to 1 mA, and the output current is limited to 3 mA. |
