MTL PCS45 Configuration Software and PCL45USB Configurator
Overview
The MTL PCS45 configurator is the dedicated configuration tool from the Crouse-Hinds series MTL intrinsic safety product line, enabling MTL temperature converters and pulse isolator modules to be configured directly from a standard Windows PC. The package comprises the PCS45 configuration software and the PCL45USB interfacing link – an ATEX-certified hardware adapter that connects the PC, via USB, to the 3.5 mm configuration jack on the target MTL4500 or MTL5500 series converter module while it remains installed and on-line in the field.
As an experienced supply partner for MTL configuration tools and software within the Cooper Crouse-Hinds series, Seven Star LLC proudly supplies the PCS45 configurator to instrumentation teams and process automation integrators across Oman and the wider GCC. Our technical team supports converter parameterization, configuration file management, and commissioning workflow guidance for MTL isolator and converter fleets throughout the Sultanate of Oman.
Operating Principle
For the MTL PCS45 system, the PCL45USB hardware provides the physical interfacing link between the target converter module and the PC running the PCS45 software, using a built-in cable fitted with a 3.5 mm jack plug that connects directly to the ‘Config’ socket present on MTL4500 and MTL5500 range converters; an adapter cable is also supplied to accommodate earlier MTL4000 and MTL5000 series modules for backward compatibility. Because the PCL45USB carries its own ATEX intrinsic safety certification, engineers can configure a converter while it remains installed and energized on-line in the field, without the need to remove the module to a safe area or interrupt the process loop it serves.
Once connected, the MTL PCS45 software reads and writes the converter’s configuration parameters – including input/output ranges, linearization tables, alarm thresholds, and pulse scaling depending on the specific module type – directly over the PCL45USB link. Configurations can be saved to disk for record-keeping and change management, reloaded to quickly replicate settings across multiple identical converters, and printed out to support commissioning documentation and factory acceptance testing packages.
Engineering Design of the MTL PCS45
The MTL PCS45 software requires approximately 20 MB of hard disk space and runs on Windows 2000, Windows XP, Windows 7, or Windows 8 operating systems, with Eaton’s MTL product line providing guidance for use on newer Windows versions where required by site IT standards. The software’s primary focus is configuration of the MTL4500 and MTL5500 range of temperature converters and pulse isolator modules, though the same PCS45/PCL45USB toolset extends compatibility back to the earlier MTL4000 and MTL5000 generation of products still in service across many legacy process plants.
The MTL PCS45 PCL45USB link itself is a compact, field-portable USB dongle with an integrated 3.5 mm configuration cable, requiring no external power supply beyond the USB connection to the host laptop or PC. This makes the PCS45/PCL45USB package a practical field commissioning and maintenance tool that instrumentation technicians can carry directly into the plant to configure, verify, or reconfigure MTL converter modules without disturbing panel wiring or removing devices from service.
Key Features
The MTL PCS45 configuration software and PCL45USB interfacing link streamline commissioning and maintenance of MTL converter fleets:
- On-line, in-field configuration of MTL4500 and MTL5500 series temperature converters and pulse isolators.
- ATEX-certified PCL45USB interfacing link permits configuration without removing modules from service.
- Backward compatible with earlier MTL4000 and MTL5000 range converter modules via adapter cable.
- Configurations can be saved to disk, reloaded, and printed for commissioning documentation.
- Compact ~20 MB software footprint compatible with Windows 2000 through Windows 8 environments.
- USB-powered interfacing hardware requires no separate power supply in the field.
- Simplifies replication of configuration settings across multiple identical converter modules.
- Supports change management and factory acceptance testing documentation workflows.
Industrial Applications
The MTL PCS45 configurator is used throughout process plants running MTL4500 and MTL5500 series temperature converters and pulse isolators: refinery instrumentation rooms, offshore platform control systems, LNG processing facilities, and any site standardized on MTL intrinsic safety interface modules for temperature and pulse signal conditioning. Instrumentation technicians rely on the tool during initial commissioning, periodic recalibration, and troubleshooting when converter output ranges or alarm setpoints must be verified or adjusted.
With fast quotation turnaround and technical support, Seven Star LLC distributes the PCS45/PCL45USB package to instrumentation and automation contractors, EPC firms, and plant maintenance teams across Muscat, Sohar, and the Salalah free zone, supporting both new MTL converter deployments and ongoing maintenance of installed intrinsic safety interface fleets. We supply on request with lead time confirmed at quotation for instrumentation tooling procurement, with full documentation support available for Oman and GCC project handover packages.

MTL product families listed here
Most of the listed items are DIN-rail galvanic isolators. The MTL5541 repeater power supply and the MTL5576-THC temperature converter belong to the MTL5500 range, and the MTL 5043 repeater power supply comes from the earlier MTL5000 range that many plants still run. The MTL 9370-FB2 is a fieldbus barrier for intrinsically safe FOUNDATION fieldbus spurs. PCS45 software with the PCL45USB link is the configurator for MTL converter modules. For the listed part CPM08-BN, please send a label photo so the number can be matched to the manufacturer's records. Newer labels show Eaton MTL, older ones Measurement Technology Ltd, and the module numbers are the same.Where MTL barriers and isolators are used
These interfaces sit in marshalling cabinets wherever instruments are located in Zone 0, 1 or 2 areas: gas plants, refineries, offshore platforms, tank farms and chemical units across the GCC. They power 2-wire transmitters, pass HART, convert thermocouple signals and drive solenoids or alarms while limiting energy to the field circuit.Ordering MTL modules: what we need
Send the full module number including every suffix, for example MTL5576-THC and not just MTL5576, and the quantity. Tell us if the module mounts on DIN rail or on a backplane, because MTL5500 and MTL4500 parts are not interchangeable. For a fieldbus barrier give the number of spurs and the enclosure reference. A photo of the side label, which shows the certificate numbers, helps when the certificate for your project file must match.Browse MTL (Eaton) products by category: Isolator & Barrier, Automation Software.
