National Instruments Relay Module SCC-RLY01 User Manual
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.
Conventions
The following conventions are used in this guide:
