2.3.8Connection With Dry Contacts

The M500D monitoring module provides 8 sets of alarm dry contacts through the J3-J6 sockets on the connector board S6415X2. Each set has a normally open contact and a normally closed contact. Once the corresponding alarm event occurs, the dry contact will act to report alarms under the control of M500D monitoring module. Through the dry contact networking, the system can realize the level isolation transmission of fault signals.

When delivery, each set of dry contacts is corresponding to one default alarm type, and users can reset it as other alarm types.

Connecting method

After peeling the signal cable terminal, insert it into the dry contact terminal, then tighten the hold-down bolt to compress the signal cable.
