RDx-S-xxxPx- Spring Return For ball valves Wiring: Connect wires according to chart below. Full schematic found on next page: Colour White Black Blue Brown Grey Pink Description +24VDC +/- 20% Power Gnd Signal (provide 24V) Limit Switch Common Limit Switch - Valve Closed Limit Switch - Valve Open Connect the power: The RDx-S-xxxPx may be connected to voltages ranging from 20– 24 VDC The power consumption will range from max. 4.0 to approx. min. 100mA when the actuator is active. When not moving, the actuator draws less than 60mA. Locate the correct connection terminals as shown in the picture below then connect power according to the connection schematics to the right.

Connect the signal: . Locate the correct connection terminals as shown in the picture above then connect your input signal on terminal 4 as shown below. RDx USER SUPPLIED 1 Open switch output Closed switch output Common to switches 24V + External I/O device supplied by user < 1mA Power cycling: If you choose to not use an external I/O device, you can set up the device so that it opens when power turns on, and closes when power turns off. In this case, the switch between terminal 4 and 6 is always closed. Functionality of the RDx-xxxPx Input#1 Action taken (Terminal 4) Low (GND) Moves to or...

Torque and Speed RDM Torque Time to open Time to close 90in-lbs 4 seconds 2 seconds (2 seconds when power is lost) RDU Torque Time to open Time to close 600in-lbs 10 seconds 10 seconds (18 seconds when power is lost) Note: Open and close times are for the actuator. The valve may be fully open or closed before the actuator reaches these limits. Thermal Cutoff: This UL approved part is found inside the enclosure, connected to the circuit board. When overheated it will sever the electrical connection, allowing the actuator to close itself via spring return. Spring Return: This unit is capable...
