This serial port module operates in harsh environments

The DS-MPE-SER4OPT is a multiprotocol opto-isolated serial port module that is designed for rugged environments. Its extended temperature capability of –40 to 85ºC enables the board to operate in many outdoor applications. Additionally, the board may be custom-configured with 0-ohm resistors in place of jumper blocks for use in high-vibration areas. Each of the board’s four serial ports offers up to 500-V isolation from the system ground. Opto-isolation increases reliability in applications with long cable runs, where a difference in ground potential can cause significant damage. The module measures only 2 in. x 1.18 in., and weighs 8.5 g.— Diamond Systems Corp., Mountain View, Calif.
