Description


RPBS-868 is device intended for wireless transfer of commands in unlicenced radio frequency range. It has four galvanically isolated digital inputs, four relay outputs and additional relay for indication of valid connection. On front panel there are LED indications of power supply, inputs, outputs, receive level and rotating switches for device setting and testing. Range up to 2km is achieved with small rod antenna and up to 16km with high gain antenna. Power supply is 230Vac and it is intended for 35mm DIN rail mounting.


Operating

RPBS-868 is used in pair with one more same device. Devices need to be adjusted to have crossed address and same channel number for communication. Digital inputs on first device are transffered to relay outputs of second device and vice versa. Relay for indication of valid connection is turned on if communication is established, and it is turned off if communication fails in matter of one second. Rotating switch for testing provide various modes for easy device setting and testing.
