3.6 Communication Module Connections
3.7 RS-485 Connection
Please refer to
Figure 3-13
for the Communication Module illustration.
The module provides VCC, RS-485, dry contact, and EPO terminals for different
use. The maximum supply current of VCC(16V) is 0.8A. The maximum input
rating of dry contact connector is 250Vac/ 30Vdc/ 9A.
