Phoenix Contact’s new universal temperature transducers belonging to the MACX Analog family of isolating amplifiers have been developed and produced in accordance with the functional safety standard in all steps of the product lifecycle. The modules include a signal input for a resistance thermometer, thermo elements, resistance-based transmitter, potentiometer, millivolt sources, as well as for customer-specific characteristics.
Therefore, just one device type covers a wide range of applications. While the 17.5 mm version has one signal output, the 35 mm version has three limit value relays, which can be interconnected as safety-related alarm outputs.
All MACX Analog modules can be freely programmed using the FDT/DTM configuration software. This software also allows the user-friendly recording and monitoring of plant and system states. Further, the temperature transducers can be locally configured using an operator control and display unit, which can additionally be used to read process values and to copy settings quickly.
Versions designed for a wide-range supply can be used in all supply systems around the world without the need for additional power supply units, therefore reducing installation costs. The optionally available PIT spring-cage connection system means that they can be connected up without tools.
The Ex MACX Analog product family includes all of the essential functions – even intrinsically safe inputs. The devices are certified corresponding to current ATEX and IECEx standards for installation in hazardous zone 2 and for Ex-i circuits up to hazardous zones 0 (gas) and 20 (dust).
They offer a high degree of safety through the combination of high signal flexibility with 3-way isolation and SIL2 certification. These features reduce the design and operating costs of the plant or system.
