Specification

Inputs

4 Optically-isolated digital inputs

A. Requires 5 - 24 Vdc supplied from +12V_

opto to 0V_opto terminals

B. Optical isolation offers improved 

performance in electrically noise environments

C. Internal 12Vdc current limited (50mA) 

supply available where an external supply is 

not required; using this supply requires  

by-passing the optical isolation of these inputs

D. Opto-isolated digital inputs work with:

1. Switch closure from the IN_opto to 0V_opto

• For use with both momentary and 

maintained inputs

• Minimum momentary input pulse 

duration 20 msec

• Switch will see up to 16mA when 

closed

2. Open collector NPN active low circuit

• On-state voltage ≤ 1 volt and 

capable of sinking 16 mA

• Collector-emitter leakage current ≤ 

500 nA

• Collector-emitter voltage ≥ supply 

voltage

3. Actively driven circuit

• Active low voltage ≤ 1 volt and 

capable of sinking 16 mA

• Active high voltage ≥ supply – 0.25 

volts

E. All opto-isolated digital inputs wire with 2 

part connectors with screw terminals. Wire 

sizes 4mm2 (12 AWG) to 0.25mm2 (24 AWG).

4 Analogue / digital inputs

A. Individually programmable as analogue or 

digital inputs

B. 5Vdc & 12Vdc current limited (50mA total) 

regulated supplies available for analogue / 

digital input devices

C. Analogue input mode:

1. Suitable for use with rotary and linear 

variable resistors

2. Reads input voltages from 0 – 10 Vdc

3. Inputs protected for use up to 12 Vdc

D. Digital input mode works with:

1. Switch closure from the IN_A/D to 0V_A/D

• For use with both momentary and 

maintained inputs

• Minimum momentary input pulse 

duration 20 msec

• Switch will see up to 60uA when 

closed 

2. Open collector NPN active low circuit

• On-state voltage ≤ 500mV and 

capable of sinking 60uA

• Collector-emitter leakage current ≤ 

10 uA

• Collector-emitter voltage ≥ supply 

voltage

3. Actively driven circuit

• Active low voltage ≤ 500mV and 

capable of sinking 60uA

• Active high voltage ≥ supply – 1 volt

4. All analogue / digital inputs wire with 2 part

connectors with screw terminals. Wire sizes

4mm2 (12 AWG) to 0.25mm2 (24 AWG).
