Moore Industries
Moore Industries is an American manufacturer of signal interface instruments, founded in 1968 by engineer Leonard W. Moore in North Hills, California. Its first product was the SCT signal converter, built in a friend's workshop. The company has been at its North Hills headquarters since 1974 and still designs and builds its products there, known for rugged aluminium housings. Seven Star LLC, an independent supplier in Oman, lists Moore Industries temperature transmitters, limit alarm trips, isolators and a PID backup controller, and sources units and replacements by full model number.

Moore Industries product families on this page
The manufacturer’s catalog is arranged by function, and many of the items listed here map onto it directly:
- Temperature transmitters: the TRX, and the STZ functional safety dual input smart HART transmitter
- Alarm trips: the SPA2 programmable limit alarm trip, including an SPA2 with HLPRG input and four relay outputs
- Signal isolators, repeaters and converters: the SIX
- PID controllers and backup stations: the 535 in 1/4 DIN format
Other catalog groups include temperature assemblies and sensors, I/P and P/I converters, remote I/O, HART gateways and interfaces, indicators, and fieldbus device couplers.
Where Moore Industries instruments are used
These are control room and marshalling cabinet devices, plus field-mounted transmitters. Typical jobs are isolating a 4-20 mA loop between two systems, converting a thermocouple or RTD signal for a DCS input, adding an independent high or low trip next to the control system, and keeping a control loop running on a backup station when the main controller is out of service. Process plants in oil and gas, chemicals and power across the GCC use them for exactly these tasks.
Moore Industries products we list
Ordering Moore Industries instruments: what we need
Moore Industries model numbers are built from fields separated by slashes: unit, input, output, power and options, followed by the housing code in brackets. Every field matters. Send the complete string from the label, the serial number, and for programmable units the input type and range you want set. State any hazardous area or functional safety requirement, because approved versions are ordered with their own option codes.

Frequently Asked Questions
How do I read a Moore Industries model number?
The label shows a string such as unit / input / output / power / options [housing]. For an SPA2 alarm trip, for example, HLPRG is the programmable current and voltage input and 4PRG means four programmable relay outputs. Copy the whole string exactly, including the bracketed housing code, since a DIN rail unit and a field enclosure version are different order items.
Which Moore Industries temperature transmitter suits a safety instrumented function?
Among the listed models, the STZ is the one the manufacturer positions for functional safety, with dual sensor inputs and HART. The TRX is a general purpose programmable temperature transmitter. For a safety loop, ask for the manufacturer's safety manual and certificate for the exact model number, and check them against your SIL calculation.
What is the difference between the SPA2 and the SPA2IS alarm trip?
Both are programmable limit alarm trips. In the manufacturer's range, the SPA2IS is the version with associated intrinsically safe inputs, so it can accept a signal directly from a hazardous area without a separate barrier. A standard SPA2 needs a barrier or isolator in front of it. Confirm the designation on your label before ordering.
Can a Moore Industries 535 controller be replaced like for like?
Only if the full order code matches. The 535 code, such as 535-21120BD000, defines the output modules, options and supply fitted at the factory. Send that code and the serial number. If the manufacturer no longer supplies the configuration, we ask for its recommended successor and send you the comparison before you decide.
Is Seven Star LLC a distributor of Moore Industries?
No. Seven Star LLC is an independent supplier and is not a distributor or agent of Moore Industries. We source Moore Industries transmitters, isolators and alarm trips through commercial channels, check the model or order code against the manufacturer's documentation before ordering, and provide the manufacturer's datasheet and the certificates the manufacturer issues with the order on request.
