Current Output/Universal Output
Figure 2-10 shows the Output and Alarm wiring connections for models with Current
Output and two-relay outputs (Model DC330X-KE-XXX).
See Table 2-3 for relay terminal
connections for Output Algorithm
selected.
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.
Electromechanical relays are rated at 5 Amps @120 Vac or 2.5 Amps at 240 Vac .
