National Instruments SCC-RLY01 用户手册

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.

The following conventions are used in this guide:
