CAUTION

Open collector outputs are internally powered at +30 Vdc. Connecting an external power supply will damage the controller.

2 Alarm #2 is not available with Time Proportional Duplex or Three Position Step Control unless the Dual Relay option is used.

3Electromechanical relays are rated at 5 Amps @ 120 Vac or 240 Vac or 30 Vdc. Customer should size fuses accordingly. Use Fast Blo fuses only.
