STZ Functional Safety HART Temperature Transmitter Now Includes Intrinsically-Safe Sensor Connections
Moore Industries announces the newest member to the Associated Intrinsically-Safe (AIS) family of products with the release of the SIL 2/3 capable STZ Functional Safety Dual Input Smart HART® DIN-style Temperature Transmitter with Associated IS sensor connections.
The STZ is certified by exida to IEC61508 for systematic integrity up to SIL 3 and for single use in Safety Instrumented Systems (SIS) up to SIL 2. The STZ is designed and developed in strict compliance with IEC 61508 standards to provide the highest level of system integrity and reliability.

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.
Installation costs are reduced if an associated apparatus (STZ-DIN with -AIS option) is used, since the associated apparatus includes the barrier in the receiving device. There is no need for the additional cost of the IS barrier, cabinet space, high integrity clean ground connection, separate power supply, or custom vendor backplanes.
This drastically reduces the cost of purchasing, installation, and maintenance versus more traditional approaches requiring a separate Zener or isolating barrier.
Blue connectors on the THZ3-DIN with -AIS option provide a visual way to recognize the Associated IS capability.
The STZ-DIN configures quickly and easily to accept a single or dual input from a wide array of sensors and analog devices including RTDs, thermocouples, resistance and potentiometer devices, and direct millivolt inputs. This 2-wire (loop-powered) Associated IS transmitter provides 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. The Universal mounting bracket easily snaps on and off of 35mm Top Hat DIN-rails and standard relay tracks.
The STZ-DIN -AIS provides HART compliance with exception-based reporting and dynamic variable mapping as well as HART Access Control to prevent unauthorized or accidental reconfiguration of the STZ-DIN while it is performing its safety function.
An additional security feature allows users to set HART communication into a Read Only or Off mode. For extra convenience the STZ is HART & DTM Programmable with user-oriented basic configuration for fast and accurate setup. It is HART configurable via any HART handheld configurator or HART compatible host.
The STZ-DIN is part of Moore Industries’ FS Series products, which are designed and built in compliance with IEC 61508, the leading worldwide functional safety standard. 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).
