Hardware Construction & Component Details
The 45C69 contains two independent electromechanical relays on a single PCB. Each relay provides both normally open and normally closed contact options. The module includes flyback diode protection across each relay coil. This protection suppresses voltage spikes from inductive load switching. The 45C69 stores no energy beyond momentary relay coil magnetic fields. Therefore, you get safe and predictable behavior during power-down sequences.
Installation & Wiring Guidelines
Mount the 45C69 into any AutoMate 15/20/30/40 rack slot. The module uses a 10-position removable terminal block for field wiring. Wire each output’s common terminal back to your load’s return path. For robust power protection in your control panel, consider a device like the RMS-TSG-TZ-C Static Trip unit from Siemens (see Alibaba link). That trip unit complements the 45C69 by ensuring clean power for sensitive logic circuits.
Status Indication & Diagnostics
The 45C69 features two red LED indicators on the front panel. Each LED lights up when its corresponding relay coil energizes. This visual feedback helps you troubleshoot field wiring quickly. The module also reports output status back to the processor. Consequently, your PLC program can monitor each output for proper operation.
Compatibility Notes
This dual output module works exclusively with AutoMate series programmable controllers. It does not support standalone operation or other PLC brands. The Reliance Electric 45C69 replaces older part numbers 45C68 and 45C67 directly without configuration changes.
