The REO board piggy backs on the AEPOC-2100 and adds four Form C relay outputs to the AEPOC. These relays can be operated through the event structure or user programs for general purpose control output.
The REO uses miniature sealed printed circuit board latching relays. SPDT form C contacts are brought to 300 VDC terminal blocks. Two relays are automatically reset with hardware, and two relays maintain settings (latched) during power outage.
