Part of Moore Industries’ FS Functional Safety Series, the SIL 2 and SIL 3 capable STZ Functional Safety Dual Input Smart HART® Temperature Transmitters for your SIS (Safety Instrumented System) configures quickly and easily to accept a single or dual input from a wide array of sensors and analog devices.
These 2-wire (loop-powered) transmitters provide an isolated and linear 4-20mA output proportional to the input. This signal is ready for direct interface with HART or non-HART based Safety System, DCS, PLC and other computer-based SCADA systems. FMEDA (Failure Mode Effects and Diagnostic Analysis) reports are available with the required safety data to ensure that the STZ meets the requirements of each Safety Instrumented Function (SIF).
The intrinsically-safe -AIS option for the STZ-DIN allows direct connection of sensors located in hazardous locations by including an embedded intrinsically-safe barrier in the front end of the STZ-DIN. The STZ-DIN -AIS is an associated apparatus suitable for mounting in Non-Hazardous or Class I, Division 2/Zone 2 hazardous locations with sensor input terminals connected to sensors or equipment in Class I, II, III, Division 1/Zone 0/1 hazardous locations.
