Inputs
The TV-UC683T has inputs that accept the following signal types.
Signal Type
Description
Thermistor
1
Precon Type 2 (10kOhm at 77 °F)
Input voltages should be from 0.2 Vdc to 4.0 Vdc for thermistors
Dry contact
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.
0
–
5 Vdc
0
–
10 Vdc
The input impedance of the TV-UC683T is approximately 120 kOhm when configured as a
voltage input.
Pulse counter
2
Pulse counting up to 10 pulses per second.
Minimum pulse width (on or off time) required for each pulse is 50 msec.
1
To use a thermistor not listed above, you can set up a
custom translation table
(page 38) for your sensor in the
controller's driver.
2
The TV-UC683T can perform pulse counting for dry contact or voltage inputs if you assign the input to a Pulse to
Analog Input microblock. See
To adjust input and output properties
(page 28).
