8643 Power I/O Box

Brand: Burkert Fluid Control Systems
Does not ship to VA, United States

The Power I/O Box Type 8643, Burkert offers a system that allows extremely cost effective connection of distributed binary signals to a process control system. Communication takes place via fieldbus in accordance with the IEC 61158. 

The hardware offers 4 intrinsically safe digital outputs making it possible to control a wide range of intrinsically safe actuators such as solenoid valves, relays or indicator lights. 8 intrinsically safe digital inputs operate in accordance with Namur specifications. 

This enables a broad spectrum of binary sensors ensuring that users are not limited to a specific manufacturer when selecting actuator or sensor technology. The device with the FF H1 interface offers DO and DI function blocks in a number of different versions in order to meet all of the demands programmers place on such systems. 

A variety of housing materials including polyester and Aluminum offers additional enhancements for the field of application.
