Ethernet Modbus TCP 2DI, 4AI and 2AO Module

Ethernet Modbus TCP 2DI, 4AI and 2AO Module

Yotta Control A-1812 Remote Modbus module provides 2 digital inputs, 2 Analog Inputs (0/4 to 20 mA), 2 PT100 Analog Inputs and 2 analog outputs. It uses optical isolators to prevent ground loop effects and limits damages from power surges. Ethernet interface supports a Modbus TCP protocol. A USB comm port is also available for Modbus communications and configuration.

Like most of the Yotta Control Modbus modbus, this unit can configured (with the utility linked below). 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.
