Contact Closure Ratings
Five Input Terminals
•
Accept maintained inputs and momentary inputs with 40 msec minimum pulse times.
•
Off-state leakage current must be less than 100 uA.
•
Open circuit voltage: 24 V
•
Inputs must be dry contact closure, solid state, open collector, or active-low
(NPN)/active high (PNP) output.
- Open collector NPN or active-low on-state voltage must be less than 2 V
3.0 mA.
- Open collector PNP or active-high on-state voltage must be greater than 12 V
source 3.0 mA.
Five Output Terminals
•
Provide maintained or momentary (1-second) outputs.
•
The GRX-IO and OMX-IO are not rated to control unclamped, inductive loads.
Inductive loads include, but are not limited to, relays, solenoids, and motors. To control
these types of equipment, a flyback diode must be used (DC voltages only). See
diagram.
