Distributed I/O Modules RS485 Modbus for analog & digital signals

A series of 14 DIN rail modules offering all common analog inputs and outputs, plus digital I/O as either separate or combined function modules. These suit systams based on the Brainchild HMI series on this website, or our own RampX systems. They are used to build low cost distributed systems for data aquisition and control. System visualisation is possible depending on the HMI used. Isolated modules are recommended for analog voltage and current and thermocouple inputs although lower cost non isolated versions are available. Communications software is available as a free download, and this allows integration with any third party devices which can act as Modbus RTU masters.
