Project Description



Compact-M2 R20

Receiver version with (8-36 VDC) DC power supply and customer-specific cabling. The receiver has 12 PWM outputs, 8 digital outputs, 2 digital inputs and a forced guided emergency stop relay. As a special feature, this receiver also offers up to 8 analog outputs especially for Danfoss valves. As interfaces, the
Compact-M2 R20 has 2 CAN interfaces and one RS232 interface.

The antenna is available both internally and, on request, externally with an extension cable.

  • Voltage: 8-36 VDC
  • Small, compact and robust housing design
  • Protection class IP65
  • CE
  • Individual solution adaptation according to specifications.

The teach-in function enables an optimized utilization of the joystick movement. By setting the min/max values on the transmitter side, the maximum move of the joystick is optimally utilized. As a result there are no longer any dead joystick motions. Even a minimum deflection of the joystick causes the immediate opening of a valve.


Multi-user system

The multi-user system enables radio communication between several transmitters and several receivers. Each transmitter can be optionally operated with several receivers at a workplace and / or vice versa. Provided that this connection is not otherwise used at this moment.
