Cycle Length Control – This speed control feature allows field adjust- ment of opening and closing cycle times, 19 minutes for 25% duty and 57 minutes for 75% duty actuators. Feedback (0-1000 ohm) Potentiometer – provides a variable resis- tance to signal the exact position of the output shaft and the valve it is powering. Position Indicator Board – provides a 4-20 mA valve position feedback signal to the control room. Heater/Thermostat – prevents condensation from collecting inside the actuator. Condensation Drain Plug – drains accumulated water. 180° Center-Off Kit – provides an extra position for three-way valves and is used for dribble-feed applications in quarter-turn valves. Additional Limit Switches – may be used to operate lights that indi- cate valve position or to operate other equipment. AF-17 Positioner Board – for control valves positions the actuator based on an input signal of current, voltage or resistance. DFP17 DataFlo P™ – is a microprocessor-controlled electronic posi- tioner with software for on-site or remote operation and diagnostics. This new, smart positioner for Series 75 actuator driven control valves is controlled by a 4-20 mA analog signal from a PLC or digital- ly from a computer. DFC17 DataFlo C™ – is a microprocessor based PID single-loop con- troller that accepts a variety of process inputs. All process parameters are easily programmed through the keypad or via a simple RS-485 computer interface. I 75 Low-Current Circuit Interface – is a solid-state interface/relay between the PC/controller/computer and actuator motor(s). It pro- tects controlling device outputs from destructive feedback. This high-voltage feedback is due to limit switch action, auto transformer effect of unused winding, and capacitor voltage. The unit, as a printed circuit board, is conveniently mounted inside of standard enclosures. Maximum output ratings are 4 A for 120 VAC and 2 A for 240 VAC. Controllers with outputs that have low current ratings cannot be con- nected to electric actuator motor(s) that require a current greater than the controller rating. R 75 Remote Terminal Unit (RTU) – is an interface for DC powered actuators. This solid-state interface card allows you to control a DC- powered electric actuator by a control signal from the Remote Terminal or any low current system (such as a solar powered sys- tem). It is equipped with a field-adjustable current limiting circuit, which will trip the power in case of abnormal conditions (it will reset by reengaging the control signal). Optional contact closure to indicate the tripped condition; 0-5 VDC, 0-1000 ohm position feedback, and end of travel SPDT gold contact switches are available.
