Remanufactured GE-Emerson IC630MDL304 Series Three Combination Input and Output Module

The GE-Emerson IC630MDL304 Series Three Combination Input and Output Module is a dual function module with input circuits each designed to receive a single discrete (ON/OFF) signal from user supplied devices, and output circuits each capable of controlling user supplied discrete (ON/OFF) loads. Typical input devices include limit switches, pushbuttons, and relay contacts. Typical loads include motor starters, relay coils, and indicator lights. A 24VDC power supply must be provided by the user. This supply provides the power to sense the state of the inputs and also provides the DC power source for the output circuits.

The 16 input circuits and 16 output circuits are connected to the appropriate input devices or user loads through field wiring to a 36 screw-terminal connector mounted on the faceplate. Input and output terminals are each arranged in two groups with eight terminals in each group, numbered 0 to 7. The top 16 terminals are for inputs, the lower 16 terminals are for outputs. Each terminal will accept one No. 12 AWG or two No. 14 AWG wires.

When installed in an I/O slot, a 32-point I/O module uses 32 consecutive I/O references, i.e. the 16 references assigned to that slot and the next 16 references. A 32-point I/O module in slot 1 would use references 00-37. In this case, an I/O module installed in slot 2 would have a starting reference number of 40. If an 8-slot base was filled with 32-point I/O modules, that base would contain 256 I/O points (references 000-377, if first base unit).
