UT-5510A optoelectronic isolation data-parallel I/O controller is an interface with 8-bit, 4-channel data input and output; each data input or output channel is similar to several computer interfaces. In this optoisolator relay, the module can be remotely controlled by a series of commands via Modbus-RTU protocol, and communicates with the host by command data via RS-485 serial bus.

The communication baud rate is software-configurable, and the maximum transmission rate is up to 115200bps, using a 4-channel wireless relay.
