The MODEX series includes a temperature measuring transducer mounted on-site in the same way as a rail-mounted terminal. The module transforms the signal received from the Pt100 temperature sensor into a proportional, load independent 4 to 20 mA output signal. The sensor circuit is intrinsically safe according to Ex protection type Ex ia. An output current exceeding the 4 to 20 mA range signals a senor fault (open/short circuit). The Pt100 temperature sensor can be operated in 2-wire or 3-wire circuits in Zone 0 or Zone 1.
