BIG-K-3-1/12 Intrinsic Safety Barrier Temperature Input
Product Description
Setting up or changing the barrier parameters is performed using special software on a PC connected to the barrier via the BIG-NP adapter.
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.
- Has external cold junction compensation.
- Configurable via DIP switch.
- The barrier has a built-in self-diagnostic function.

| Output parameters | |||
| Output signal | 4-20 mA | ||
| Regardless of the input signal fault condition (except for an open or short circuit, when the output is 0 mA), the output signal matches the input signal within the measurement range. The maximum value will not exceed 110% of the upper limit of the measurement range. For example, with a 0-20 mA output signal, the minimum value can be 0 mA, and the maximum output value will not exceed 22 mA. |
