Protect your Process Loops and Controllers

Moore Industries Signal Isolators, Converters and Splitters protect your process by converting, isolating, splitting, boosting and stepping down process signals so field instruments can interface directly with indicators, recorders, DCS, PLC, Asset Management, Control and SCADA systems. With a wide variety of products, you’ll be able to find the right one to fit your signal isolation or conversion needs. 

Our Signal Isolators and Converters:

  • Isolate signals to stop erroneous measurements caused by ground loops.
  • Convert signals so field instruments can interface directly with an indicator, recorder, DCS, PLC, Asset Management, Control and SCADA system.
  • Isolate and protect Safety Instrumented Systems (SIS) loops by using exida® certified SIL capable and HART pass-thru isolators.
  • Split one signal to allow one primary measurement to be sent to two separate systems.
  • Protect equipment and signals (area isolation) by eliminating common electrical paths.
  • Amplify signals so that more instruments can be added to an overburdened loop.
  • Solve “bucking” power supplies by stopping a conflict caused by a 4-wire transmitter and a DCS both trying to power the same process loop.
  • Solve DCS start-up problems caused by non-isolated transmitters by installing an isolator in each troublesome loop.

SRM-SST-SSXSSX and SST Functional Safety Isolators and Splitters

These exida® certified SIL 2/3 capable 2-wire and 4-wire Isolators and Splitter provide isolation and signal splitting for your Safety Instrumented Systems (SIS) needs. These units protect and enhance loops and also pass valuable HART® data from the field transmitter to host systems and vice-versa. They isolate your SIS from your Basic Process Control System or monitoring system so disconnections or failures to these secondary systems don’t affect your safety system.

HIT_HIX_Hrail_Moore_Industries

HIT/HIX 2- and 4-Wire HART® Isolators

HIX/HIT HART® Isolators provide highly economical solutions to common and costly problems that plague many of today’s “smart” process loops. Protect and enhance your HART investment with the 2-wire (loop-powered) HIX or the 4-wire (line-mains powered) HIT. These isolators maintain HART diagnostic and process data transfer to your control or asset management system. With the passive input, you can perform equipment maintenance without interrupting the control loop, allowing output devices to be taken offline. By standardizing on HART-capable isolators, you can ensure compatibility and communication with HART field devices.

ECT-Family-HiResECT-DIN 2- and 4-Wire Signal Isolators, Convertors, and Splitters

ECT DIN-style signal isolators, converters, repeaters, boosters and splitters are rugged and reliable and available in 2-wire (loop) and 4-wire (line/mains) powered models. The complete family delivers economical solutions for an expansive range of signal interface applications. With superior signal isolation capabilities of up to 1500Vrms, the devices safeguard against ground loops, motor noise, and electrical interferences. They can also amplify signals to accommodate additional instruments in an overloaded loop and split process signals, allowing two isolated signals to be sent to separate locations. Additionally, the dual channel I/O models offer application flexibility while reducing space and costs. The 15mm wide housing for 4-20mA, 1-5V, and 0-10V inputs enables fitting 40% more isolators in the same space as 25mm housing.

SIX_pp

SIX 2-Wire Signal Isolator, Converter and Repeater

The versatile SIX functions as a signal isolator, converter, and repeater, making it ideal for installation in both plant and control room settings. The 2-wire (loop-powered) SIX derives its power from the process loop, eliminating the need for an additional power supply. It features repeater/diverter capabilities, enhancing drive capability to a process loop and allowing the installation of additional instruments on the loop. It can also divert a secondary signal from a process loop to a recorder, indicator, or similar device. With an exceptionally low current impedance of 50 ohms for a 4-20mA input, it doesn’t load existing loops and regenerates the signal effectively.
