Inputs
Control signal See Model Chart for actuator models and control type.
Power
See Model Chart. All 24 Vac circuits are Class 2. All circuits 30 Vac and above are Class 1. Half wave
device.
Connections
Models with -0xx have 3 ft. (91 cm) appliance wire connections. Models with -1xx have 3 ft. (91 cm)
plenum wire connections. Enclosure accepts 1/2 in. (13 mm) conduit connectors.

Outputs
Electrical
Position Feedback Voltage: For voltage ranges, the feedback signal is the same range as the input
signal. The 4 to 20 mAdc current input range have a 2 to 10 Vdc position feedback signal. The position
feedback signal can supply up to 0.5 mAdc to operate up to four additional slave actuators. The MS51-
7103-040 and -140, MS51-7203-040, MS61-7203-040 do not have feedback.
Mechanical
Linear Stroke: See Model Chart.
Approximate Stroke Timing: See Model Chart.
Manual Override: Allows positioning of valve and preload using manual crank.
