Field of application

Unsurpassed reliability, accuracy and long-term stability in critical processes over all industries. The configurable transmitter not only transfers digital converted signals from RTD and TC sensors, it also transfers resistance and voltage signals using FOUNDATION Fieldbus™ communication. High measurement point availability by means of sensor monitoring functions and device hardware fault recognition. Optimization of the measurement accuracy by sensor-transmitter matching.

2 universal input channels and FF™ protocol for the conversion of input signals into digital output signals
The device stands out due to signal reliability, long-term stability, high precision and advanced diagnostics (important in critical processes)
For the highest level of safety, availability and risk reduction
Installation in flat-face terminal head as per DIN EN 50446
Optional installation in field housings even for use in Ex d areas - with mounting brackets for wall or pipe mounting

Benefits

Easy and standardized communication via FOUNDATION Fieldbus™ H1
Straightforward design of measuring points in Ex-areas through FISCO/FNICO conformity in accordance with IEC 600079-27
Safe operation in hazardous areas thanks to international approvals such as FM IS, NI; CSA IS, NI; ATEX Ex ia, Ex nA for intrinsically safe installation in zone 1 and zone 2
High accuracy through sensor-transmitter matching
Reliable operation with sensor monitoring and device hardware fault recognition
Several mounting versions and sensor connection combinations
Rapid no-tools wiring due to optional spring terminal technology
