Product Categories
West Controls products cover four main categories — from cost-effective single-loop instruments to safety-critical limit controllers and multi-channel process controllers.
Single Loop PID Temperature & Process Controllers
West Controls' single loop controllers are cost-effective, front-of-panel instruments designed to control one temperature or process variable with accuracy and ease. Models range from essential, fast-to-configure units to feature-rich platforms with advanced auto-tuning, alarms, communications and flexible plug-in I/O options.
- 1/32, 1/16, 1/8 and 1/4 DIN panel sizes
- Universal sensor input — thermocouple, RTD, linear mA/V
- Relay, SSR driver, triac and linear mA/V outputs
- Auto-tuning PID for fast, stable control
- Optional RS485 MODBUS communications
- Front USB port for configuration and data logging (Pro-EC44)
- Blue Control© PC configuration software
Process & Temperature Indicators
West Controls' process indicators display temperature, pressure, flow, humidity and other process variables with high-visibility LED displays. Optional alarms and communication and retransmission capabilities allow seamless integration with plant control systems and PLCs.
- High-contrast, high-visibility LED display
- Dual-colour display — green to red automatic alarm change
- Jumperless configuration and plug-in output boards
- Up to 4 alarm relays — latching or non-latching
- PV retransmission and transmitter power supply option
- RS485 MODBUS communications option
- PC configurator for quick setup
Multi-Loop & Multi-Zone Process Controllers
West Controls' multi-loop controllers simultaneously manage multiple process variables — temperature, pressure, flow and level — in a single compact unit. A cost-effective alternative to PLCs for dedicated process control applications where multiple variables must be controlled with precision.
- Simultaneous control of multiple loops/zones
- PID, on/off and ratio control modes
- 4–20 mA, 0–10 VDC and relay output options per loop
- Suitable for heating, cooling and valve control
- Lower cost and simpler than PLC for dedicated control
- Compact panel-mount design
- MODBUS communications for SCADA integration
Limit Controllers — Fail-Safe Process Protection
West Controls' limit controllers are purpose-built safety devices designed to protect equipment, processes and personnel by preventing operation beyond predefined temperature or process limits. These controllers play a critical role in meeting safety standards and ensuring reliable system operation in demanding environments.
- Fail-safe design — latched relay output on limit trip
- Manual or remote reset after a limit trip
- Universal sensor input — TC, RTD and linear
- LED status indication for trip and alarm conditions
- Independent of the primary control loop
- Meets safety and industry standard requirements
- 1/16 and 1/4 DIN panel sizes available
