Power Requirements
All 24 Vac circuits are Class 2. All circuits 30 Vac and above are Class 1.
Connections Mx4D-703x-0x0 and Mx4D-803x-0x0: 3 ft. (0.9 m) long, appliance cable, 1/2 in. (13 mm)
conduit connector. For M20 Metric conduit, use AM-756 adaptor.
Mx4D-703x-1x0 and Mx4D-803x-1x0: 10 ft. (3.05 m) long, plenum cable, 1/2 in. (13 mm)
conduit connector. For M20 Metric conduit, use AM-756 adaptor.
Motor Type Brush DC.
Outputs
Electrical
Position Feedback Voltage: For 0 to 3 Vdc, 0 to 9 Vdc, and 0 to 10 Vdc proportional
actuators, the feedback signal is the same voltage range as the input signal. The 4 to 20 mA
proportional actuators and floating actuators have a 2 to 10 Vdc feedback signal. The feedback
signal can supply up to 0.5 mA to operate up to four additional slave actuators.
Mechanical Stroke: 93° nominal.
Manual Override: Allows positioning of valve shaft, using a manual crank.
Output torque rating: 30 lb-in (3.4 N-m).
RA/DA Jumper (Proportional Models): Permits selection of reverse acting or direct acting
control.
Position indicator: Visual indicator.
