SFAR-S-16DO

Modbus I/O Module
SfAR-S-16DO gives users a possibility to send multiple signals to multiple devices, for example, to start/stop or alarm reset commands for pumps.

16 Digital Outputs
The module has 16 digital outputs (DO). Digital outputs are PNP transistor outputs, sending voltage signals. All outputs are isolated from the logic with optoisolators.

Simplified Configuration and Commissioning Process
A built-in RS485 interface allows an easy connection over the Modbus RTU/ASCII protocol. A 32-bit ARM core processor provides fast processing and communication.
The module is equipped with a set of LEDs used to indicate the status of I/Os, power supply, and RS485 communication.
Configuration of the module is carried out with our free software, the SfAR Configurator. A built-in mini USB allows for performing a primary configuration of the unit without an additional power supply.
To simplify the installation, the module has been equipped with the Quick Connector system. Using a dedicated SfAR-S-LINK cable allows for connecting up to 10 modules, which provide both RS485 communication and external power supply.
