Current output/ universal output connections

Figure 2-12 shows the Output and Alarm wiring connections for models

with Current Output (Model DC330X-KE-XXXand Model

DC330X-C0-XXX). See Table 2-5 for wiring restrictions.

For Control and Alarm Relay Contact information, see Tables 2-7 and 2-8.

For Duplex Current Output use Auxiliary Output for Output 2 (cool) (see Figure 2-14).

ATTENTION:

All current outputs are isolated from each other, case ground, and all inputs.

1Electromechanical relays are rated at 5 Amps @120 Vac or 2.5 Amps at 240 Vac. Customer should size fuses accordingly. Use Fast Blo fuses only.

Relays are NOT available on DC330X-C0-XXX. 24167
