Products | KET-RMB-211

Master ModBUS RTU Wireless

The KET-RMB-211 can handle up to 32 ModBUS RTU slave devices connected to its RS485 port. The device can be programmed to read a set of registers and send them to the Gateway.

The integrated Repeater functionality reduces the number of required nodes and increases network reliability.

Is equipped with an extended radio range that allows to reach over 1000 m in free air.

The standard antenna connector supports 90° joint antennas or cabled ones for placement outside the electrical panel.

Maximum flexibility of power supply, direct from the mains or low voltage, both DC and AC.

Format suitable for mounting in electrical panel on DIN-rail.
