Application
The MP-5200 Series actuators are for the electronic 
proportional control of dampers, valves, or program 
switches which require the return to normal position 
upon power interruption. This series is compatible with 
2 to 15 Vdc input signals from TAC System 8000
TM
, 
TAC NETWORK 8000
®
, and TAC DMS DDC 
controllers.
Features
• Linear motion output shaft controlled by a variable 
dc voltage input signal.
• Spring return.
• Nominal 3 Vdc operating span.
• Fixed start point and non-positive positioning. 
• 10,000 Ω or greater input impedance.
• 24 Vac, 120 Vac, and 240 Vac models
• Optional adjustable SPDT auxiliary switch.
• Available in damper models or base models that 
require damper or valve linkage.
• Die cast lower housing and painted steel upper 
housing.
• Hydraulic actuator with oil-immersed motor, 
transducer, and pump.
• Internal feedback circuitry provides non-positive 
positioning control in relation to the controller signal.
