Need help?Do you have a question about the Regada REMATIC SPR 1PA and is the answer not in the manual?
The REMATIC electric part-turn actuator, featuring the DMS3 electronics module, is designed for both modulating and ON-OFF operations. It offers versatile control options, including binary inputs (+24V DC) for OPEN, STOP, CLOSE, and EMERGENCY commands, as well as analog input signals (current 0/4-20 mA, voltage 0/2-10 V). For advanced integration, the actuator supports communication via PROFIBUS DP V0/V1 or MODBUS RTU networks. Parameter settings can be configured locally using pushbuttons and blinking LED diodes on the control board, or remotely via a PC program utilizing an RS 232 interface.
Power Supply: The actuator operates on a 230V AC supply voltage. Motor Protection: It includes an internal thermal switch for motor protection against overheating. Torque Control: Switching off can be initiated by either position or torque. The switching-off torque is adjustable from 60% to 100% of the nominal torque. Torque blocking is implemented in limit positions and during startup. Relays: The device features two freely programmable relays (R1, R2) with 18 configurable functions, and a dedicated READY relay. Input Signals: Control can be achieved through unified signals (0/4-20 mA, 4-12 mA, 12-20 mA current, or 0/2-10V voltage, though the 0/2-10V option is not available for the 2P version of DMS3). Binary control is available via permanent +24V DC signals for OPEN and CLOSE, or impulse control (+24V DC) for OPEN, STOP, and CLOSE (inching duty). Output Signals: A passive 4-20 mA electronic position transmitter is included (not for the 2P version of DMS3). An auxiliary 24V DC output (max. 40 mA) is provided for supplying control inputs and the transmitter. Safety Features: The actuator incorporates a safety function (ESD - Emergency Shut Down) with configurable reactions to failures. Environmental Protection: The standard enclosure offers IP67 protection, with an IP68 option (10m/48 hours) available for specific climate resistances. Operating Angle: The operating angle can be mechanically limited or freely programmed without stop ends. Standard operating angles include 60°, 90°, 120°, and 160°, with programmable ranges up to 360°. Mechanical Connection: Flange connections conform to ISO 5211. Communication: An RS 232 communication interface is standard for PC-based parameter setting.
Control Flexibility: The actuator supports a wide range of control methods, from simple binary ON-OFF to complex modulating control via analog signals or fieldbus networks. This adaptability makes it suitable for diverse industrial applications. Local and Remote Configuration: Parameters can be set directly on the device using pushbuttons and LED indicators, or through a PC program, offering convenience for both field adjustments and centralized system management. Diagnostic Feedback: The READY relay provides status information, including errors, warnings, or the absence of a control signal, facilitating quick troubleshooting. An LED position indicator offers visual feedback on the actuator's current position. Adjustable Performance: The adjustable switching-off torque and programmable operating angle allow for fine-tuning the actuator's performance to specific process requirements, enhancing precision and operational efficiency. Timing Mode: A timing mode/regime of operation is available, which can be useful for applications requiring specific operational sequences or intermittent duty. Safety Integration: The ESD safety function ensures that the actuator can respond predictably to critical system failures, enhancing overall plant safety. Configurable reactions include opening, closing, stopping, or moving to a safe position.
Self-Protection: The motor's internal thermal switch protects against overheating, extending the lifespan of the motor and reducing maintenance needs related to thermal damage. Robust Design: The high IP protection ratings (IP67/IP68) ensure resistance against dust and water ingress, making the actuator suitable for harsh industrial environments and reducing the frequency of repairs due to environmental factors. Diagnostic Tools: The RS 232 interface and PC program provide advanced diagnostic capabilities, allowing technicians to monitor actuator status, read error codes, and perform detailed parameter adjustments, which streamlines maintenance and reduces downtime. Modular Design: The DMS3 electronics module and optional relay modules (RE1-RE5, READY) suggest a modular architecture, which can simplify repairs and upgrades by allowing individual components to be replaced or added without overhauling the entire unit. Heater: A space heater, operated by the control unit, is included to prevent condensation inside the enclosure, especially in fluctuating temperature environments, thereby protecting internal electronics from moisture-related damage.
