I/O Terminals
Terminals are provided for connecting to the inputs, outputs and 5V DC power supply.
Terminal Specifications:
Acceptable Wire Size: 26-14 AWG
Tightening Torque 0.35-0.40 Nm
DANGER! Risk of injury, short circuit, or equipment damage; disconnect all power before wiring or service.
1. GND (VX12i only)
DC Ground (V-) terminals, all terminals marked GND are common.
2. +5V (VX12i only)
A 5V DC 500mA power supply is provided for powering discrete and analog 5V sensors that connect to the
0-5V dc input terminals.
3. Inputs (VX12i only)
There are four (4) 12-bit analog input terminals for measuring 0-5Vdc or 0-20mA/4-20mA signals.
4. Outputs
There are eight (8) transistor outputs for driving solenoids, relays, contactors, etc. with a DC voltage. Six (6) of
the outputs can be configured for PWM control between 10-90% for motor speed control, light diming, etc.
