USER GUIDE

SCC-RLY01 Relay Module

The SCC-RLY01 contains one single-pole double-throw (SPDT) nonlatching relay capable of switching 5 A at 30 VDC when using an SC-2345 or SC-2350, or 250 VAC when using an SCC-68. Any single E/M Series DAQ device digital input/output (P0) line 0 to 7 can control the SCC-RLY01.

The SCC-RLY01 uses positive logic. A digital high sets the relay, and a digital low resets it. In the set state, the common (COM) contact is connected to the normally open (NO) contact. In the reset state, the common (COM) contact is connected to the normally closed (NC) contact.
