Digital Inputs

The digital inputs are designed to be powered using an external power supply. A wide range of digital input devices can be used such as push buttons, limit switches and electronic proximity switches. Current through an input (in either direction) results in a logic 1 in the status register. Power to operate the field devices must also be supplied by the user.

Digital Outputs

The output points are arranged in one group of eight points with one common. The output switching capacity of each output is 2 amps. The relay outputs can control a wide range of load devices such as motor starters, solenoids and indicators. Power for the internal relay circuits is provided by the +12VDC bus on the backplane. The user must supply the AC or DC power to operate the field devices. An internal fuse protects the relay contacts should ratings be exceeded.
