DESCRIPTION

The SerialComm ISO-485-P is a bi-directional passive industrial (wide temperature range) RS-485 surge protector. It can protect any standard half duplex RS-485 port from transients, peaks, and spikes caused by lightning and other power surges. The ISO-485-P protects the 2 lines: 485+ and 485-. The unit is passive, therefore, no external power or flow control is required.  The ISO-485-P provides three stages of protection for maximum safety. The first stage is a gas discharge tube. The second stage is a series of protection resistors. The third stage is 600W Transient Voltage Suppressor (TVS). All three stages of protection are provided for each of the RS-485 lines. When the ISO-485-P is placed close to the RS-485 device it is protecting, it will suppress any voltage levels above 6.8 volts without affecting the normal operation of the data transmission. When installing the ISO-485-P is very important that the ground screw is connected to earth ground with a minimum of 12 AWG copper wire.  The ISO-485-P has a 3-wire terminal block on one RS-485 side and a 2-wire terminal block on the other RS-485 side.
