Notes
AI1 to AI4 can be configured for timed override
capability.
Typically used for fan speed switch.
These inputs may be configured to be thermistor or
resistive inputs, 0–10 Vdc inputs, or 0–20 mA inputs.
Low impedance relay contacts recommended.
Minimum dwell time is 25 ms On and 25 ms Off.
The UC400 controller provides the 24 Vac that is
required to drive the binary inputs when using the
recommended connections.
Power needs to be wired to the binary output. All
outputs are isolated from each other and from ground
or power. Ranges given are per contact.
Use for modulating TRIAC. User determines whether
closing high side (providing voltage to the grounded
load) or low side (providing ground to the power load).
Ranges given are per contact and power comes from
TRIAC SUPPLY circuit.
Each termination must be configured as either an
analog output or binary input.
Pressure inputs supplied with 5 volts of power.
