                                                                      Overview

                                                                      IC694MDL740 is a 16-point transistor digital output module of GE Series 90-30 PLC. It can be mixed-mounted on PACSystems RX3i dual-bus backplanes to reuse original 90-30 field wiring during system upgrade. It receives control instructions from the CPU and outputs 24VDC switching signals to drive field small loads such as indicator lights, auxiliary relays and solenoid valves.
