REVO RT LOOP

REVO RT Loop Multi-Zone PID Temperature Controller

A modular, multi-loop temperature control platform for electrically heated machinery, built for OEM integration, predictable thermal stability and simplified panel engineering.

REVO RT Loop is designed to replace traditional panel-mount temperature controllers or reduce PLC PID loop complexity by consolidating multi-zone temperature control into a modular back-panel system.

Why Gets Hard to Scale

As machines grow from a few heater zones to dozens, temperature control can become a wiring, commissioning and troubleshooting burden - especially when loops are distributed across multiple standalone controllers.

Panel space & wiring complexity

More zones usually means more controllers, more wiring, and longer build time.

Commissioning overhead

Commissioning dozens of loops across devices increases risk and extends FAT/SAT timelines.

Diagnostics gaps

When a zone misbehaves, it’s hard to pinpoint whether the issue is sensor, output, or load.

REVO RT Loop addresses these challenges by consolidating multi-zone PID control into a modular platform with structured diagnostics and predictable integration.

What Is

REVO RT Loop is a multi-zone PID controller designed for modular rear/back-panel installation. It can operate independently or communicate with a PLC for supervision, setpoints and monitoring.

Core concept

  • Multi-loop control in a compact, modular format
  • Designed to replace multiple panel-mount controllers
  • Structured for OEM builds, commissioning and long-term maintenance

Energy & load management (system-level)

In multi-zone heating systems, coordinating control and monitoring helps stabilise thermal behaviour and supports smarter operating strategies (e.g., coordinated warm-up, consistent zone performance, faster fault isolation).
Note: integrate with appropriate power drive units (thyristor/SSR) as required by the load and zone current.

How

REVO RT Loop manages heating via logic (SSR) outputs connected to external drive units. Temperature feedback is acquired via thermocouple or analogue inputs and controlled using PID hot/cold strategies.

Inputs

  • TC inputs for standard industrial temperature sensing
  • Analogue inputs for process sensors where required

Outputs

  • SSR logic output to drive external power units
  • Relay output available for auxiliary functions / alarms

Modularity & scaling

Choose 3, 6 or 9 loop modules and scale branches to match machine architecture. This reduces repeated panel-mount hardware and supports consistent loop deployment across platforms.

for OEMs and Industrial Users

The CD Automation thyristor power controller range is engineered for long-term operation in demanding industrial environments where uptime, consistency, and durability are critical.

Faster build & commissioning

Centralised multi-loop architecture reduces wiring and speeds up repeatable deployment across machine variants.

Better thermal stability

High-resolution PID control supports tighter temperature control, reduced overshoot, and improved product consistency.

Maintenance-friendly diagnostics

Load diagnostics help locate issues in the load circuit faster, reducing downtime and troubleshooting time.

PLC-ready integration

Designed for modern automation architectures with industrial comms options (Modbus RTU/TCP and common fieldbus/industrial Ethernet variants depending on configuration).

Scalable multi-zone platforms

From compact machines to large multi-zone systems, REVO RT Loop supports structured scaling without redesigning the control concept each time.

PLC, SCADA and Industrial

REVO RT Loop is designed to fit into OEM automation architectures — either running independently or reporting to a PLC / SCADA layer for monitoring, alarms and data capture.

Common integration patterns

  • PLC sets setpoints / recipes and reads temperatures and alarms
  • Central monitoring for multi-zone machines (e.g., ovens, hot-runner, extrusion)
  • Structured FAT/SAT commissioning with repeatable configuration

Comms options

Communication options may include Modbus RTU, Modbus TCP, and industrial Ethernet / fieldbus variants depending on selected configuration.

Confirm protocol availability by module code during quotation.

Typical

REVO RT Loop is well suited for machines requiring reliable multi-zone temperature control with clear diagnostics and scalable architecture.

Plastics machinery

Extrusion lines, heads, hot-runner systems.

Multi-zone ovens & furnaces

Zone based temperature control wherestability and repeatability drive product quality.

Infrared heating processes

Drying and curing with IR lamps.

Ideal for OEM platforms

Standardise a single multi-zone control architecture across machine variants to reduce engineering time and improve repeatability in production.
