Manufactured and designed in Sweden, Westermo has expanded its range of wireless Ethernet modems with RM-240.

With an operating temperature of -25 to +70 Deg C and an operating voltage of 10-60Vd, with configuration RM-240 can be an access point, client/station, bridge, repeater or router.

to provide wireless links between serial and Ethernet devices the modems excel in utilities, process control and manufacturing.

The RM-240 can connect to a range of devices such as PLC’s, HMI’s, DCS, data acquisition, video and industrial PC’s. Each modem features an Ethernet port (10/100 BaseT) as well as two serial ports (RS-232 and RS-485) and onboard I/O for local and remote link status.

Suitable for long and short range applications, the RM-240 has a sight range of 1km with suitable antenna. Distance covered can range from 1 to 10km depending on the antennas and repeater function.

A high RF output and superior receiver sensitivity give good penetration for reliable data transfer in congested industrial environments.

Data transfer is secured using military grade 128-bit AES encryption, plus commercial WEP encryption. A firewall offers further protection with message filtering at the MAC address level.
