SPECIFICATIONS
Actuator Inputs
Control Signal: See Table-1 for actuator models and control type.
Power Input: See Table-1. All 24 Vac circuits are Class 2. All circuits 30 VAC and above
are Class 1.
Connections: 3 ft (91 cm) appliance wire or plenum cables, enclosure accepts 1/2” (13
mm) conduit connectors. For M20 Metric connector, use AM-756 adaptor.
Actuator Outputs
Electrical:
Position Feedback Voltage (proportional or floating only),
For voltage ranges, the feedback signal is the same range as the input signal. The 4-
20 mAdc current range and floating actuators have a 2-10 Vdc position feedback
signal. The position feedback signal can supply up to 0.5 mAdc to operate up to four
additional slave actuators.
Mechanical:
Linear Stroke, 1/2” (13 mm) nominal.
Approx. Stroke Timing, See Table-1.
Manual Override, Allows positioning of valve and preload using manual crank.
Right/Left Jumper, Permits reverse acting/direct acting linear motion (MS51 only).
Environment:
Ambient Temperature Limits,
Shipping & Storage, -40 to 160 °F (-40 to 71 °C).
Operating, -22 to 140 °F (-30 to 60 °C).
Temperature Restrictions, For maximum ambient 140
°F (60
°C) the maximum
allowable fluid temperature should not exceed valve rating. See F-27252 Selection Guide
for specific ratings.
Humidity: 5 to 95% RH, non-condensing.
Location:
NEMA 1. NEMA 2 (enclosure is air plenum rated), UL Type 2 (IEC IP54) with customer
supplied water tight conduit connectors.
