2.5 Relay Output Connections
The 2-Relay option provides two relays for external
device control. Each relay's contacts are rated for
5 A maximum. Both NO and NC contacts may
be used individually or simultaneously as shown.
Note:
Relay contacts are rated as 5 A @ 250 VAC or
5 A @ 30 VDC maximum resistive load.
To reduce the possibility of
noise interference, separate
AC relay lines from input/
output lines.
