SDM-8AI module allows measurement of voltages and currents. The values are read via RS485 (Modbus), so we can easily integrate the module with popular PLCs, HMI or PC equipped with the appropriate adapter.
The device has a set of 8 analog input measurements. Each channel can be individually configured. In addition, the module is equipped with 2 configurable digital outputs.
The module SDM-8AI communicates with all commercially available PLCs and other devices that support popular Modbus Master protocol.
This module is connected to the RS485 bus with twisted-pair wire. Communication is via MODBUS RTU or MODBUS ASCII. The use of 32-bit ARM core processor provides fast processing and quick communication. The baud rate is configurable from 2400 to 115200.
The module is designed for mounting on a DIN rail in accordance with DIN EN 5002. The module is equipped with a set of LEDs used to indicate the status of inputs and outputs useful for diagnostic purposes and helping to find errors.
Module configuration is done via USB by using a dedicated computer program - Modbus Configurator (free). You can also change the parameters using the MODBUS protocol.
