Remove the cover by looseneing the two bottom screws and removing the top two screws.

Tilt the cover back to clear the light pipes and then remove the cover.

The PCB has several connection and configuration options as described:

Component Locations

GND

IN4

IN2

+5V

GND

IN3

GND

IN1

GND

1. I/O Screw Terminal Block

Make connections to analog sensor inputs and transistor outputs.

2. Input Jumper Select Block

Set input channels to current mode (0-20mA) instead of voltage (VX12i only)

3. Power Input Terminals

Optional input power terminals for hard wire applications.

4. LED Light Pipes

Indicators for each of the eight (8) outputs; red when on. Pipes protrude through front panel openings.
