FLEXIBLE DIN RAIL SIGNAL CONDITIONING MODULES

 The MEDACS series from Status Instruments is a new concept in DIN rail signal conditioning modules, offering a high degree of functionality and configurability, together with the capability of interfacing to a wide range of industrial sensors.  

MEDACS (Modular Expandable Data Acquisition and Control Systems) is aimed at specifiers of electronic equipment in large processing plants, system integrators and specialist panel builders.

Design of the MEDACS modules meets Status’ stringent criteria for performance and reliability, emphasised by the three way optoisolation and innovative electronics packaging.  

Each unit has a RS485 serial communications link, enabling data to be sent to and from a host using Modbus protocol. An ingenious ‘bus jumper’ system allows units to be easily bussed together, removing the need for complicated and expensive back plane wiring and speeding up the installation process.  

Interfacing with other proprietary bus systems such as Ethernet, Profibus and others can be readily achieved via standard gateway modules.  

Outputs include an isolated 4-20 mA re-transmission signal, a single change-over trip relay and dual normally open relays. Units can handle standard mV, mA, temperature and frequency inputs and have, in addition, two isolated discrete digital inputs that can be used as to provide a reset function.

For high density systems, cost effective dual channel versions are available, while for systems that require more local input, single channel units featuring a built-in key pad and digital display allow the user to access critical functions without the need for a PC.

In order to increase the flexibility of the MEDACS modules, Status has pioneered the development of its Transfer Function ModuleLibrary (TFML), which is embedded in each unit. TFML is a facility that allows a software download that will perform mathematical functions between the inputs and outputs. This will adapt the MEDACS exactly to the user’s specification.
