Linear actuator with RS-485 protocol

The Idea line of programmable linear actuators now features a RoHS-compliant electronic drive and fully programmable control unit integrated with a linear actuator. The unit is suited for equipment or systems requiring a small footprint. The actuators can also communicate using an RS-485 data protocol.

The main advantage of using the RS-485 protocol is the ability for long data transmissions with immunity to electrical noise. RS-485 uses “differential” signal lines for limiting common-mode noise coupling and twisted-pair cabling for cancelling out induced noise current, allowing the devices to communicate over a 1,000-ft network without the need for termination resistors and to reach up to 256 addressable device nodes. An industrial controller can send commands to all the drives at once or control each drive separately when assigned a unique number between 0 and 255.

Hardware features include programmable current control, a single supply voltage of 12 to 48 Vdc, 2.6-Arms (3.68-Apeak) maximum rated current per phase, and eight optoisolated general-purpose I/O. Inputs are rated for 5 to 24 Vdc, 4-mA maximum/input. The outputs are open collector, 5 to 24 Vdc, 200-mA maximum/output.
