Moore Industries SLD Functional Safety Programmable Loop Display

Moore Industries has released the SIL 3 capable SLD Functional Safety Programmable Loop Display for use in safety instrumented systems (SIS). The SLD has been certified by exida with full functional safety approval after rigorous evaluation to ensure conformance with the IEC 61508 standard for safety-related applications.

The SLD is part of the FS Functional Safety Series range and the loop-powered SLD displays real-time process status in mA, per cent or any designated five-character engineering units. Built for safety instrumented functions (SIF), the SLD can be taken out of the loop with the –LMD (loop maintenance diode) option without affecting the integrity of the safety function.

The loop display is DTM programmable with user-oriented basic configuration for fast and accurate set-up. The SLD can be programmed with any FDT-compliant host or program, such as PACTware, utilising Moore Industries’ DTM and USB communication cable. DTM programmability allows the SLD to be custom-scaled to display per cent or scaled directly in engineering units to show process measurements such as pressure, temperature, level or flow.

It is loop-powered using less than 2.3 V, includes robust RFI/EMI protection, and has an easy-to-read display with two rows of large characters. With 360° mounting, the SLD can be mounted at any angle in almost any environment using one of the Moore Industries’ explosion-proof and flameproof housings.

The SLD has a high accuracy reading for any 4–20 mA signal, displaying information with an accuracy of ±0.012% of input scale.
