Controllers

The regulatory hubs of a process. These devices receive data from sensors and compare it against a setpoint to automatically adjust system outputs, ensuring stability in variables like temperature or flow.

Watlow | Thermal Loop Controllers

Watlow is the global leader in industrial heating and control. Their controllers are sourced for their “EZ-ZONE” technology, which integrates the controller, high-limit, and power switching into one unit, drastically reducing the amount of wiring needed in a control panel.

PM PLUS™

Model Number: PM6C1AJ-AAAAAAA

Bluetooth® connectivity; high-resolution text display; integrated safety limit control.

Key Technical Specifications:

  • Replaces cryptic “seven-segment” codes with a clear, full-text display for faster troubleshooting and setup.

  • Allows technicians to configure the controller and check status from a smartphone via the EZ-LINK™ mobile app.

  • Designed to fit perfectly into the same panel cut-outs as legacy EZ-ZONE PM controllers for easy upgrades.

EZ-ZONE® RM

Model Number: 0600-0072-0000

Modular system; supports up to 152 loops; high-density I/O for large-scale thermal systems.

Key Technical Specifications:

  • One “RM” system can replace dozens of individual panel controllers, saving significant rail space and wiring time.

  • Mix-and-match modules for temperature, current sensing, and digital logic within a single hardware stack.

  • Supports standard industrial protocols including EtherNet/IP, Modbus TCP, and DeviceNet.

Eurotherm (by Watlow) | Precision Process Controllers

Eurotherm (recently acquired by Watlow) is the gold standard for high-accuracy PID control. Their algorithms are so precise that they are the primary brand sourced for the pharmaceutical and aerospace industries, where even a 0.5°C deviation can ruin a multi-million-dollar batch.

nanodac™

Model Number: NANODAC/VH/X/X/LRR

Combined PID control and secure data logging; 1/4 DIN size; full-color graphical display.

Key Technical Specifications:

  • Meets 21 CFR Part 11 requirements for the medical and food industries, providing a “tamper-proof” record of the process.

  • Features a bright 3.5″ color display that shows real-time “trend” lines, making it easy to see process stability at a glance.

  • Despite its small size, it can manage two independent PID loops simultaneously, often replacing two separate instruments.

EPC3000

Model Number: EPC3008-CC-VH-LR-XX

High-precision single-loop control; cybersecurity certified (Wurldtech); rapid 125ms sampling.

Key Technical Specifications:

  • One of the first controllers to be certified to modern industrial security standards, protecting against unauthorized network access.

  • Uses proprietary Eurotherm “Cutback” algorithms to ensure the temperature never goes above the setpoint during startup.

  • Boasts a 0.1% measurement accuracy, making it ideal for laboratory furnaces and high-spec glass manufacturing.
