9172 Ex i relay modules
Relay module separates intrinsically safe and non-intrinsically safe binary signal and control circuits
The Series 9172 relay module separates intrinsically safe and non-intrinsically safe binary signal and control circuits. To do this, it makes intrinsically safe binary inputs and outputs with two channels available. Depending on the version, the device has either an intrinsically safe control system or an intrinsically safe output contact, and can therefore be used as an output or input isolator.
• Compact relay module with two channels
• For separating intrinsically safe and non-intrinsically safe signal and control circuits
• Ex i and non-Ex i actuation available
