Input and Output Overview
Each ECY IO module has a number of physical connections for inputs and/or outputs. These inputs and outputs are labelled on the ECY IO modules ac-
cording to the tables below. Input and output options must be configured properly in EC-gfxProgram to ensure correct input readings and output values.
The controller's license may have separate limits that reduce the availability of certain options.

1. An on-board 18VDC power supply can provide the necessary power for 20mA current loop sensor operation. The 0 to 20mA current loop input option is individually selected through an on-board DIP
switch setting.
2. 0 to 10VDC is available on UO1 to UO6. 0 to 20 mA is available on UO1, UO2, and UO3; this option is individually selected through an on-board DIP switch setting.
Input Wiring
Input options must be properly configured in EC-
gfx
Program to ensure correct input readings. The table below shows the ECY IO modules’ input desig-
nation for each IO model. For terminal block connector wiring best practices, see General Wiring Recommendations [pg.2]. Inputs can be connected as
follows.
Before connecting a sensor to the controller, refer to the installation guide of the equipment manufacturer.
£ For a wire length less than 75’ (23m), either a shielded or unshielded 18AWG wire may be used.
£ For a wire up to 200’ (61m) long, a shielded 18AWG wire is recommended.
£ The shield of the wire should be grounded on the controller side only and the shield length should be kept
as short as possible.
