MR-AI-1: 4 Analog Input Module 0-10VDC / 4-20mA communication over RS485 with Modbus RTU protocol 4 analog input module 0-10VDC / 4-20mA acquirable via RS485 with Modbus RTU protocol **Operation** - The module has 4 analog inputs, either voltage with a 0-10VDC range or current with a 4-20mA range, selectable by jumper. - The input value is provided as an integer multiplied by 100 (e.g., 103 -> 1.03mA). **Configuration** The communication parameters of the module are configured by writing the desired values to specific registers via Modbus RTU. The device address is set by writing to a Modbus memory area, to which an offset set via DIP switch is added. --- Source: https://shop.marcomweb.it/en/remote-io/mr-ai-1-4-analog-input-module-010vdc-420ma-modbus-rtu MARCOM S.r.l. — a trusted supplier for industrial automation and building automation.
