Input Wiring
Input options must be properly configured in EC- gfx Program to ensure correct input readings. For terminal block connector wiring best practices, see
General Wiring Recommendations. 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 10' (3m), either a shielded or unshielded 18AWG wire may be used.
£
For a wire up to 33' (10m) long, a shielded 18AWG wire is recommended.
£
The shield of the wire should be grounded on the controller side only and the shield connection to the
ground should be kept as short as possible.
£
If functional Earth is connected, input circuits will be PELV.
£
If functional Earth is NOT connected, input circuits will be SELV.
Sensor Input Type
£
Dry Contact input.
£
Pulsed input.
£
Pulse input used with a 2-wire sensor powered by its own power source.
£
This input supports a maximum input frequency of 100Hz (5ms minimum
ON/OFF) for DIx, or 1Hz (500ms minimum ON/OFF) for UIx and SIx.
£
Connect the pulse input according to the figure for a pulse meter that can
pull-down a +3.3VDC supply with a 1kΩ (for DIx) or 10kΩ (for UIx and SIx)
pull-up resistor (Internal supply type).
£
Thermistor Input (for example, 10kΩ type II and III).
£
Resistive input, maximum 350kΩ (for example, use with 10kΩ and 100kΩ
potentiometers).
£
0 to 20mA input used with a 2-wire, 0 to 20mA sensor powered by an exter-
nal power supply.
£
Voltage input used with a 3-wire 0 to 10VDC or 0 to 5VDC sensor powered
by an external 24 AC/DC power supply.
£
Voltage input used with a 0 to 10VDC or 0 to 5VDC sensor powered by its
own power source.
