Input/output Number Additional information
Digital inputs 2
Dry-contact digital inputs slow-pulsed at 10Hz.
All inputs are suitable for voltage free contacts (e.g. mechanical
switches) or NPN transistor devices (e.g. electronic proximity
switches).
NOTE: PNP transistor device inputs are NOT suitable.
Status outputs 2 Separate System OK and Setpoint Status
Analog inputs 1
0-20mA differential input; 16-bit resolution, 0.1% accuracy, 10 ohm
input impedance.
Thermocouple inputs 1
J, K or T type thermocouple with on-board cold-junction
compensation.
Cold junction compensation accuracy ±1º over ambient temp
range: -40º to +70ºC.
Power supply 1
9-30 VDC 1 Amp CSA certified Class 2 power supply. For use in
Class 1 Div 2 explosive areas, the power supply must be approved
for Class 1 Div 2 use.
