The  A-1212 is a Wifi Remote Modbus TCP module with 2 digital inputs, 2 analogue Inputs (0/4 to 20 mA), 2 PT100 Analogue Inputs, 2 transistor digital outputs and 2 analogue outputs. It uses optical isolators to prevent ground loop effects and limits damages from power surges. The  A-1219 has a Wifi port supporting Modbus/TCP communications as well as a RS485 port for Modbus RTU. A USB comm port is also available for Modbus communications and configuration.
