I/O Connection Guide
Universal Input Wiring
Universal inputs can be configured for multiple sensor types:
- Temperature Sensors (10K Thermistor): 2-wire connection, no polarity
- 4-20mA Sensors: 2-wire connection, observe polarity (+/-)
- 0-10V Sensors: 3-wire connection (24V, GND, Signal)
- Digital Inputs: Dry contact, 2-wire connection
Digital Output Wiring
Digital outputs provide on/off control for equipment:
- Relay Outputs: Normally Open/Normally Closed contacts
- Maximum Load: 1A @ 24VAC typical
- Inductive Loads: Use snubber circuits or external relays
Analog Output Wiring
Analog outputs for proportional control:
- 0-10VDC: 3-wire connection (24V, GND, Signal)
- Maximum Load: 20mA per output
- Minimum Impedance: 500Ω load
