»
The SCC-RLY01 contains one single-pole double-throw (SPDT)
nonlatching relay capable of switching 5 A at 30 VDC or 250 VAC.
Any single E 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:
Angle brackets that contain numbers separated by an ellipsis represent
a range of values associated with a bit or signal name—for example,
P0.<3..0>.
