CAUTION
The controller’s DOs control 24
Vac loads only. The maximum
rating is 12 VA for each DO. An
external interposing relay is
required for any of the following:
• VA requirements higher than the
maximum
• 110 or 220 Vac requirements
• DC power requirements
• Separate transformers used to
power the load.
(for example part number 540-147,
Terminal Equipment Controller
Relay Module)
Wiring for AI with a 4 to 20mA Sensor.
NOTE:
If the voltage/current switch is set to
current and a 4 to 20mA sensor is
connected to an AI, then special wiring
requirements must be followed.
NOTE:
When wiring any actuator that uses a 0 to
10V control signal and ties AC neutral to
DC common, an additional wire
must
connect the actuator AC neutral to the DC
common of the PTEC/TEC AO being used
to control the actuator.
