Energy Storage and Relay Protection

The GE IC693MDL940F stores energy using two electrolytic capacitors. These capacitors filter backplane power for stable relay coil operation. Each channel includes a flyback diode to suppress inductive voltage spikes. A replaceable fuse provides overcurrent protection for all sixteen output circuits. Consequently, this module protects both the PLC and connected field devices.

Installation and Status Indication

You will find sixteen clearly labeled output channels on the terminal block. Each channel features an independent green LED for visual status monitoring. The module also includes a keying mechanism for correct rack insertion. Thus, it fits seamlessly into any standard Series 90-30 I/O slot.
