The SDM-8AO has 8 analog outputs that can operate as a current output (0-20mA, 4-20mA) or a voltage output (0-10V). Voltage or output current is set using the RS485 bus (Modbus protocol), so you can easily integrate the module with popular PLCs, HMIs, or PCs with appropriate adapters.

The module communicates with all commercially available PLCs, devices that support the popular MODBUS MASTER protocol.

This module is connected to the RS485 bus via two wire twisted pair. Communication is made using the MODBUS RTU or MODBUS ASCII protocol. The use of a 32-bit ARM core processor provides fast data processing and fast communication. The transmission speed is configurable from 2400 to 115200.

The module is designed for mounting on DIN rail according to DIN EN 5002.

The module is equipped with a set of LEDs used to indicate the status of the outputs (lit when current or voltage> 0), useful for diagnostic purposes and for error finding.

Configuration of the module is done via USB with a dedicated computer program. It is also possible to change parameters using the MODBUS protocol.
