The tM series from ICP DAS is a family of network data acquisition and control modules providing digital I/O functions. The modules can be remotely controlled through an RS-485 serial bus by using DCON and Modbus RTU protocols.
The selectable transmission speed of the RS-485 port is up to 115,200 bps. Modbus has become a de facto standard communications protocol in industry and is now the most commonly available means of connecting industrial electronic devices. This makes the tM series perfect integration with the HMI, SCADA, PLC and other software systems.
