Super4 RS485 Relay Module

The SUPER4 RS485 Module is a relay control board containing 4 mechanical SPDT (Single Pole Double Throw) power relays. The module accepts serial commands on a RS485 2 or 3 wire network.

RS-485, is a standard defining the electrical characteristics of drivers and receivers for use in balanced digital multipoint systems. The standard is published by the ANSI Telecommunications Industry Association/Electronic Industries Alliance (TIA/EIA). Digital communications networks implementing the EIA-485 standard can be used effectively over long distances and in electrically noisy environments. Multiple receivers may be connected to such a network in a linear, multi-drop configuration. These characteristics make such networks useful in industrial environments and similar applications.
