Signal Description
GPO1+
• Isolated output switch
• 5–24 VDC
• 200 mA maximum
• Resettable fuse
• Reverse polarity, overvoltage, and inductive
transient protected
The General Purpose Output 1 signal pair is an

PS2+
• 24 VDC output source
• 100 mA maximum
• Resettable fuse
• Reverse-polarity and transient overvoltage
protected
• PS1+ output on pin 13 is a separate circuit
The PS2+ and G2- pin pair provide 24 VDC, 100 mA
power for external wiring to I/O signals. This pin pair
is not electrically isolated.
G2-
• Ground return and reference for the
24 VDC output
