24V Digital Gauge & Process Controller – Multi-Sensor Input
Description
The 24V Digital Gauge & Process Controller is a compact, configurable display designed to work with a wide range of compatible sensors and transducers. Depending on the connected sensor, it can be used to monitor parameters such as pressure, temperature, voltage and other analogue signals.
Its compact 48 x 24mm face size makes it suitable for dashboard and panel installations, while the bright red LED display provides clear visibility in automotive and equipment applications.
24V Digital Gauge & Process Controller
- 24V DC operation
- Compact 48 x 24mm display face
- Bright red LED display
- Programmable high or low alarm
- Built-in relay output
- Peak and minimum value recording
- Peak-hold display mode
- Adjustable display brightness
- Supports multiple analogue sensor input types
- Supports a wide range of thermocouple and RTD temperature sensors
Multi-Sensor Compatibility
The controller can be configured to work with a variety of compatible sensors and transducers. Depending on the sensor used, applications may include:
- Boost or pressure monitoring
- Exhaust gas temperature (EGT)
- General temperature monitoring
- Battery voltage monitoring
- Air/fuel ratio monitoring with a compatible external controller
- Other compatible analogue process signals
Important: Each controller can be configured to monitor one parameter at a time. It does not measure multiple sensor inputs simultaneously.
Programmable Alarm & Relay Output
The controller includes a programmable high or low alarm. When the configured alarm point is reached, the front-panel LED indicates the alarm condition and the internal relay output changes state.
The relay output can be incorporated into a suitably designed control circuit for compatible external devices such as an alarm, buzzer, cooling fan or other control equipment.
Note: Any connected external device must remain within the relay contact rating and should be installed with appropriate circuit protection.
Peak & Minimum Recording
The gauge can record maximum and minimum measured values along with the associated time information. Recorded data can be reviewed later, making the controller useful where peak operating conditions need to be monitored.
A peak-hold mode can also be selected so the maximum measured value remains displayed.
Adjustable Display Brightness
The red LED display brightness can be adjusted from the keypad and can also be configured to dim when connected to a suitable vehicle lighting signal.
Pressure Monitoring
For pressure applications, the controller can be configured to work with compatible analogue pressure transducers where the relationship between pressure and sensor output is known.
Pressure can be displayed in user-configured engineering units such as PSI or bar, depending on the calibration entered into the controller.
