The signal converter converts Ex i signals of thermocouples and resistance temperature detectors into 0/4 … 20 mA standard signals. The new devices can be operated in Zone 2 and for functional safety applications according to SIL 2. The ambient temperature ranges from -40°C to 70°C, making its application versatile and suitable for field installations in harsh climatic conditions.
Furthermore, the 9282 temperature transmitters have been designed to be more energy efficient leading up to 40% savings in energy consumption while emitting less heat. The entire isolator range for 1- and 2-channel signal transmission is available in a compact design. The slim switching repeaters, transmitter supply units and binary outputs enable an especially high signal density in an installation space that is approximately 30% smaller, thus making it an exceptionally flexible and reliable solution for safe operation of field devices in hazardous environment.
Additionally, the ISpac modules that are globally certified for Zone 1 and 2, including NEC Class 1 and Division 2, fulfil the functional safety criteria according to SIL 2 or SIL 3. Tested operating periods from over 10 to 15 years guarantees availability for the long term as well as a high standard of reliability. All modules can be mounted directly on the DIN rail, snapped onto the pac-Bus and combined across all models to make them future-proof. The pac-Bus obviates the need for individual wiring, supplies up to 40 modules with auxiliary power and when combined together with the 9193 series supply module, it provides a collective fault signaling solution that is useful for overall diagnostic purposes.
