Yotta Control A-1055 Remote Modbus module provides 8 Isolated Digital Inputs and 8 transistor PNP Digital Outputs. It uses optical isolators to prevent ground loop effects and limits damages from power surges. RS-485 interface supports a Modbus RTU or ASCII protocol.

Like most of the Yotta Control Modbus modbus, this unit can configured. A switch on the back set to INIT will force it to default communications parameters. You can then use Yotta Utility software to autodetect it and configure it. When configuration is complete set the switch to RUN.

The Yotta Control series all come with a DIN-rail and panel mount adapter. Multiple units can be stacked on top each other for high density installation.
