The unit contains the radio module, the output photo-MOSFET, and the communication monitor LEDs. This simplifies the design of radio systems for Start/Stop and monitoring of High/Low level changes.
The radio unit operates using our proprietary frequency-hopping method. This allows for simultaneous control of multiple systems in the same area without radio channel management. It also offers a Hamming distance of 6, ensuring reliable communication. The LINK LED on the communications monitor indicates the radio link status at all times.
An interface is provided for the power supply, with 6 inputs or 6 outputs, and the output terminal for the radio communication link monitor. The KSR2.4 output unit can control loads up to 35 VDC 200 mA with the photo-MOSFET output. Both high and low level input/output are possible.* *See connection examples.
