Wiring Diagrams
24 VDC
POWER
SUPPLY
4-20 mA
SENSOR
ENTIRE CIRCUIT
MUST BE ISOLATED
WITH NO EARTH GROUND,
INCLUDING THE 4-20 mA
SENSOR
DO NOT use the same transformer to power both the sensor and controller.
Each 4-20mA sensor requires a SEPARATE, dedicated 24 VDC power supply.

CAUTION:
Figure 7. Special Wiring Requirements for 4–20 mA
Sensors.
CAUTION:
The controller’s DOs control 24 Vac loads
only. The maximum rating is 6 VA for
each DO. Use an interposing 24 Vac relay
module (such as P/N [550-054, 550-048,
550-050, 550-052]) for any of the following:
• VA requirements higher than maximum
• Separate transformers to power the load
• Power limited Direct Current (DC) power
requirements
The 24Vac relay module and the circuit
described in Figure 7 are not applicable for
smoke control application.
