Phoenix Contact Mini Analog 6.2 mm isolation amplifiers

Click2Contact

Phoenix Contact’s Mini Analog range of 6.2 mm isolation amplifiers provides a fault monitoring system function for easy error logging in multichannel applications.

The monitoring module provides group error logging for up to 80 modules connected via the mounting rail bus connector. If an error is detected internally or at the signal input of a transducer, it is reported via the rail-mounted connector and displayed in the control centre via the fault monitoring module’s NC contact. Time-consuming individual evaluations are no longer necessary.

Depending on the type of isolation amplifier, the following errors can be signalled: bottom or top threshold of measurement range exceeded, wire breakage, short circuit and module fault. In conjunction with the new feed terminal, any failure in the power supply is detected and reported immediately. Both on the participant side and in the analysis module, fault evaluation can be configured freely. As a result, fault monitoring is especially suitable for modular systems.

The updated system function is supported by two new temperature transducers for resistance thermometers and thermocouples, as well as a new frequency transducer. Other new components include a constant voltage source and an output loop-powered isolator.
