Designed with a building-block concept for remote I/O bus interface and distributed intelligence, the RIO (remote I/O) terminal block modules consist of a terminal block base module and a selectable bus-dependent, plug-in electronic module that's compatible with Profibus-DP, Interbus, and WorldFIP. Terminal strips on the block accommodate two- or three-wire field devices such as sensors and actuators. Dimensions for the combined terminal block and plug-in electronic assembly are 4.02" wide x 4.41" high x 3.07" deep. Each electronic bus module includes eight digital inputs and outputs, and I/O can be added with an expansion terminal block. Expansion is in increments of eight digital inputs and outputs, 16 digital inputs or 16 digital outputs in a single module.
