Ex i temperature transducer: converts signals from resistance temperature detectors installed in the Ex area and transmits a 0/4 - 20 mA signal to a load in the safe area. Freely programmable, 3-way isolation, SIL, Push-in connection, standard configuration. 

## Your advantages 

- 

- Power supply possible via DIN rail connector 

- Programming during operation with Ex measuring circuit connected and also voltage-free using IFS-USB-PROG-ADAPTER programming adapter 

- 

- 

- 

- 

- Input for resistance thermometers and resistance-type sensors, [Ex ia] IIC 

- Installation in zone 2, protection type "ec" (EN 60079-7) permitted 

- 3-way electrical isolation 

- Status indicator for supply voltage, cable, sensor, and module errors 

- Configuration via software (FDT/DTM): sensor type, connection technology, measuring range, measuring unit, filter, alarm signal, and output range 

- 

- Output: 0 mA ... 20 mA or 4 mA ... 20 mA
