Holes are threaded for ¼-20 and are approximately .275” deep. For dimensions see page 7.

Wiring: The actuator comes standard with a Turck 6 position connector and a 20’ cable with plug. Cut the cable to the length required and then connect according to the following wire color schematic: Wire color schematic for “Turck 6” cable: Turck connector not included in the Class 1, Div 1 Groups B, C & D rated explosion proof enclosures. Appropriate rated cable glands or conduit should be installed by qualified personnel in accordance with site requirements.

Connect the signal: Locate the correct connection terminals as shown on the previous page, then connect your input signal on pos. 1 and 2 as shown below. Feedback, if applicable is connected to positions 3 and 4. RDx Input #1 Input #2 External I/O device supplied by user < 1mA RDx series with manual override The actuator is certified for hazardous locations. The additional manual override gear case and handle do not require a certification. Operation of the manual override when power is applied will be difficult as the actuator will try to maintain the valve in the position it has been...

Operation DIP switches: The DIP switches allow you to change the settings on your actuator. To flip a switch, gently use a small flat-head screwdriver. See chart below for DIP switch functionality. DIP switches. In this example DIPs 1, 2, 6 and 12 are on. DiP 1 Off Off On On Fastest settling Medium-fast Medium-slow Slowest settling Use only for low torque valves Typical setting Typical setting Use for high torque valves Switches 1 and 2 set the actuator position control parameters. High settling speed settings are suitable for fast positioning of light valves. Longer settling times will...

Functionality of the RDx-xxxDT: The RDx can operate as a 3-position or 4-position actuator. The 4th position is enabled by turning Dip 8 ON. 3-pos Functionality (Dip 8 OFF) Input#1 (Pin 1) High Low High Low Action taken Moves to or remains in center position Moves to or remains in right position Moves to or remains in left position Moves to or remains in right position (Input#1 has precedence over Input #2) The feedback from the RDx-xxxDT is as follows: Output#1 Output#2 Meaning High = 4.5vDC Low = 0.8vDC (Pin 3) (Pin 4) High High Actuator output is in center position High Low In Right...

Torque Settings: Effect of power settings and speed settings: To accommodate different valves and other applications with different torque requirements, the actuator can be set to apply different torque on the valve stem when in the seating mode. Please see table on pg. 4 to select the power setting that is right for your application. The actuator will use 100% of available torque to try and reach maximum speed. Current drawn will be limited proportionally to the DiP setting applied actuator will automatically slow down and deliver the maximum available torque for a given “Permanent Power...

Main Dimensions: RxL/RxM Desiccant sticks: These sticks change colour when exposed to moisture. When they change from the original color, blue, to pink, the actuator has been exposed to an excess of moisture.
