Relay Contacts and Interlock

 Delta Isolated Contacts

This interface provides 4 changeover relay contacts, an interlock (in addition to the standard SM3300 interlock) and an Enable input. The relay contacts can be controlled/monitored by Ethernet commands. The Interlock and Enable input can be monitored by Ethernet commands.

 

Relay Contacts (CON M & CON N)

 

Relay contacts are as described below, during power off and when not set. The relay contacts can handle a maximum contact voltage of 60VDC. The maximum continuous current is 2A.

 

Pinning CON M:

 

6 = Relay 1 NC

5 = Relay 1 NO

4 = Relay 1 Common

3 = Relay 2 NC

2 = Relay 2 NO

1 = Relay 2 Common

 

Pinning CON N:

 

6 = Relay 3 NC

5 = Relay 3 NO

4 = Relay 3 Common

3 = Relay 4 NC

2 = Relay 4 NO

1 = Relay 4 Common

 

INTERLOCK & ENABLE (CON K)

 

The Interlock input (pin 1) is initially connected to pin 3 (common). Replace the link by two wires and a switch (eg. a cabinet door switch) when it's function is required.

 

The Enable input (24V, pin 2) impedance is approximately 12kOhm and has a working range of 15V - 30V. Connect the common of the external voltage to pin 3.

 

The Interlock and Enable can not be used simultaneously. All Interlocks should be valid.

 

Pinning CON K:

 

3 = Common

2 = Enable

1 = Interlock
