Features:
- Switches 110 V AC field circuits from a GEM80 I/O rack.
- Uses the exact 8178-4002 output-module configuration.
- Works with the field supply and protection defined by the original cabinet.
The -4002 ending is essential because the 8178 family includes other output arrangements.
Processor commands are translated into controlled AC switching for the assigned field loads.
Circuit voltage, commoning and load duty must be checked individually before reconnection.
Availability is confirmed against the complete 8178-4002 identity, required condition, quantity and delivery destination at quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Switch legacy 110 V AC actuators from a GEM80 controller.
- Restore discrete field outputs in an existing GEC automation cabinet.
- Maintain process interlocks that rely on the original AC output wiring.
- The module must remain inside the protective environment of its GEM80 cabinet.
- Ventilation and contamination control are important for aged switching components.
- Field wiring insulation must remain suitable for the 110 V AC circuit class.
- Isolate the external AC supply independently of controller power before handling terminals.
- Prove zero voltage and secure driven equipment against unexpected motion.
- Restore circuit covers and protective earthing before operational testing.
- Each used channel follows the processor output assignment in the application.
- External commons and fuses define the energized field-circuit groups.
- Output proving should confirm both commanded state and actual device response.
