Input connectors
Each input consists of a wire/pin pair (that is, input/Gnd). T o ensure proper operation, each
pair to be used must be connected to an external sensor that provides a dry -contact closure.
The customer sensor output connects between an optically isolated 5 VDC signal and an
isolated return.
F or an OPEN circuit (logic 0 ) between pins:
• There is 10 K Ohms or greater across the input pair .
• The signal to ground voltage is +5 VDC .
F or a CLOSED circuit (logic 1 ) between pins:
• There is 1 K Ohms or less across the input pair .
• The signal to ground current is a maximum of 9 mA.
Either of the above states can be defined by the customer in system software as an alarm
condition.
Output connectors
Each output consists of 3 -wires/pins:
• COM
• NC
• NO
The customer output device control inputs connect between the common (COM) and either the
normally closed (NC) or normally open (NO) contacts of a relay . The NC and NO state for relay
contacts occurs when the relay coil is not energized.
Relay contacts are load rated for a maximum of 1 A at 24 VDC and 0.5 A at 50 VDC .
The toggling of relay contacts to the opposite state is controlled by system software.
