£ Pulse input used with a 2-wire sensor powered by its own power source – this in-
put supports a maximum input frequency of 1Hz (500ms minimum ON/OFF).
Connect the pulse input according to the figure for a pulse meter that can pull-
down a +5VDC supply with a 10KΩ pull-up resistor (Internal supply type).

ECY IO Module Input Wiring
Output Wiring
Output options must be properly configured in EC-
gfx
Program to ensure correct output values. The table below shows the ECY IO modules’ output des-
ignation for each IO model. For terminal block connector wiring best practices, see General Wiring Recommendations [pg.2]. Outputs can be connected
as follows.
Before connecting an output device (actuator, relay, etc.) to the controller, refer to the datasheet and installation
guide of the equipment manufacturer.
£ For a wire length less than 75’ (23m) long, either a shielded or unshielded 18AWG wire may be used.
£ For a wire length up to 200’ (61m) long, a shielded 18AWG wire is recommended.
£ The shield of the wire should be grounded on the controller side and the shield length should be kept as
short as possible.
£ For relay outputs (DOx); select appropriately-sized wiring suitable to the current load.
