Status MEDACS 2100 Universal Input to RS485 MODBUS Converter

The MEDACS is a totally new signal conditioner and consists of a family of DIN rail modules, each one having a high degree of functionality and configurability via a RS485 MODBUS serial communications interface. They accept all common signals and produce an isolated (4 to 20) mA re-transmission signal, a single changeover trip relay, twin normally open relays or various combinations.

For high density systems, dual channel versions are available or for systems that require more local input, single channel versions with an in-built keypad and digital display are available where functions can be accessed via the front panel keys.

Each unit comes complete with a RS485 serial communications port which enables the devices to be integrated into a complete process control system. Unit wiring is simplified and speeded up by using the integral 'bus jumper' system provided with each unit which removes the need for complicated and expensive back plane wiring as it connects comms and power to each device.

The functionality is further enhanced by our Transfer Function Module Library (TFML) software option which enables MEDACS to perform maths functions between inputs and outputs. These can be PID Control, tank linearisation curves, signal accumulators, max and min data logging etc. All the TFML’s published on our web site can be downloaded free of charge via the links below. Alternatively, for a small fee, we can write custom functions to match your specific application.
