!
Do not attempt to increase load current or wattage capability beyond the maximum
rating by connecting 2 or more outputs in parallel. The slightest variation in relay
switching time may cause one relay to momentarily switch the total load current.
Apply only +24V dc power to the power terminals on the terminal base unit.
Make certain that all relay wiring is properly connected before applying any
power to the module.
Total current draw through the terminal base unit is limited to 10A.
Separate power connections to the terminal base unit may be necessary.
