Wiring inputs and outputs
Inputs
The TV-UCXP683T has inputs that accept the following signal types.
Signal Type
Thermistor
1
Dry contact
0–5 Vdc
0–10 Vdc
2
Pulse counter
1
To use a thermistor not listed above, you can set up a custom translation table for your sensor in the controller's
driver.

The TV-UCXP683T can perform pulse counting for Dry Contact or Binary Input if you assign the input to a Pulse
to Analog Input microblock. See To adjust input and output properties.
Outputs
Analog outputs
Analog outputs can be used for 0-10 Vdc devices. Resistance to the ground must be 500 Ohms minimum.
NOTE The device must share the same ground as the controller.
Binary outputs
There are 2 banks of relays. Each bank contains 3 built-in relays with dry contacts that share a common bus input.
An external voltage source must be wired to the common Bus connection for each bank of relays.
Each relay can be used to switch the voltage provided on its associated bus terminal to an external device or
relay. Each relay can switch up to 3.75 A, 30 Vac/Vdc. The total power and current that can be switched by a bank
of 3 relays cannot exceed the Class 2 limits of 100 VA or 4.2 A.

Installation and Start-up Guide
Description
Precon Type 2 (10kOhm at 77 °F)
Input voltages should be from 0.2 Vdc to 4.0 Vdc for thermistors
The maximum current when the contact is closed is 0.5 mA. The input voltage should be 4.1
V when the contact is open. Maximum closed contact resistance is 1kOhms.
The input impedance of the TV-UCXP683T is approximately 120 kOhm when configured as a
voltage input.
Pulse counting up to 10 pulses per second.
Minimum pulse width (on or off time) required for each pulse is 50 msec.
