Moore Industries has introduced a new Functional Safety Loop Display for industrial use. The PC programmable unit monitors and displays real time process status using one of several engineering units specified by the operator. The unit is certified by exida as a SIL 3 capable, non-interfering device for use in a safety loop.

The following excerpt from the Moore Industries blog tells more of the story...

"The SLD features an independently configured display with two rows of large characters that can be clearly read in the field and set to display any EGU, it is loop-powered by less than 2.3 Volts, and the Loop Maintenance Zener Diode Option allows removal from the loop for maintenance without interrupting your safety function. Additional features include RFI/EMI immunity, superior accuracy of ±0.012% of input scale, easy calibration, and superior reliability with up to 5 years between scheduled calibrations.

"The SLD Functional Safety Programmable Loop Display is DTM programmable. Using the Moore Industries’ optional USB communication cable, the SLD can be configured to display the signal how you want to see it using any FDT compliant host or program framework, such as free PACTware. You can even store the configuration you’ve created directly to your computer.

"The SLD is simple to setup with DTM software, allowing the SLD to be custom scaled to display information in percent or scaled directly into engineering units for indicating process measurements such as pressure, temperature, level, or flow. Use the free software to input custom and square root curves in one EGU and have the PC program convert it into a different EGU for display, or easily program span, zero, input range, display range, and filtering frequency. Select square root or linear curve from the library or quickly create a custom one for your use.

"When placed into one of our housings, the SLD has 360° flexible mounting allowing the SLD to be mounted at any angle in nearly any environment. The SLD is a non-interference device and can be taken out of the loop with the –LMD option (Loop Maintenance Diode) without affecting the integrity of the SIF loop. The SLD Functional Safety Programmable Loop Display is the perfect solution to accurately and reliably display process status in a safety loop."
