Wireless Router
MRD-350

The ED-210 is an industrial Ethernet router designed to allow remote connections to sites using the integral PSTN modem, or to allow sites to be directly connected to each other using an analogue circuit. The modem can provide connection rates up to 33.6 kbit/s, however data compression can increase the data throughput. A 4 port managed switch allows several industrial units (PLCs, HMIs or drives) to be connected locally.

Using a PSTN dial back solution for remote access provides an incredibly secure solution avoiding using the Internet for access. A simple port level IP firewall allows unwanted traffic to be filtered which can add to security, but can also ensure that unwanted traffic is not passed through the low bandwidth modem connection.

The modem is equipped with transient protection on the line side and a “watchdog” that monitors and automatically resets the modem in the event of a fault; a critical function on unmanned sites. The wide power range, galvanic isolation on all ports and compact design make it ideal for easy installation in industrial applications.

Only industrial grade components are used which gives the ED-210 an MTBF of 558,000 hours and ensures a long service life. A wide operating temperature range of –25 to +65°C (–13 to +149°F) can be achieved with no moving parts. The ED-210 has been tested both by Westermo and external test houses to meet many EMC, isolation, vibration and shock standards, all to the highest levels suitable for heavy industrial environments and rail trackside applications.
