QL-CA1I220 Thresholds Overshooting Warning Station

The QuakeLogic QL-CA1I220 is a thresholds overshooting warning station for sensor-based alarm monitoring. It supports 4–20 mA input, two configurable thresholds, alarm and pre-alarm relay contacts, 4-character display, manual alarm reset, 230 Vac power supply, and an IP66 cast aluminum enclosure.

OVERVIEW

Description

Thresholds Overshooting Warning Station

The QuakeLogic QL-CA1I220 is a thresholds overshooting warning station designed to monitor sensor values and trigger alarm outputs when a preset threshold is exceeded.

It continuously checks the measured input value from connected sensors. Therefore, it is suitable for wind alarm, level alarm, and environmental threshold monitoring applications.

When the measured value exceeds the configured limit, the unit commands relay contacts for alarm or pre-alarm signaling. As a result, external warning devices can be activated automatically.

Alarm and Pre-Alarm Monitoring

The QL-CA1I220 supports two threshold levels. One threshold can be used for pre-alarm, while the other can be used for alarm condition.

Typical applications include:

  • Wind alarm monitoring
  • Level alarm monitoring
  • Threshold overshooting detection
  • Environmental monitoring stations
  • Industrial warning systems
  • Remote field alarm stations
  • Sensor-based safety alerts
  • Sirens and flashing light activation

Moreover, the system requires manual reset after an alarm condition. This helps ensure that alarm events are not ignored.

Sensor Input and Threshold Configuration

The QL-CA1I220 works with sensors using a 4–20 mA signal range. Therefore, it can be connected to compatible wind or level transducers.

Configuration and display features include:

  • 4–20 mA measurement range
  • Two configurable thresholds
  • Pre-alarm threshold
  • Alarm threshold
  • Push-button threshold configuration
  • Regulation potentiometer for limit selection
  • 4-character numeric display
  • Instant value visualization
  • Threshold value configuration

In addition, the display allows operators to view instantaneous sensor values and configure alarm levels.

Relay Outputs and External Warning Devices

The unit includes relay outputs for external alarm equipment. Therefore, sirens, flashing lights, or other signaling devices can be connected directly to the internal relay contacts.

Relay and output features include:

  • Alarm contact output
  • Pre-alarm contact output
  • Relay contacts for external warning devices
  • Maximum load of 8 A at 230 Vac
  • Alarm condition activation
  • Pre-alarm condition activation
  • Alarm activation during system malfunction
  • Alarm activation during power supply blackout

Because of this relay design, the system can support safety-focused warning applications in field monitoring installations.

Rugged IP66 Housing

The QL-CA1I220 is housed in an IP66 cast aluminum enclosure. As a result, it provides waterproof protection and resistance to adverse environmental conditions.

Housing and operating features include:

  • IP66 protection grade
  • Cast aluminum box
  • Waterproof enclosure
  • Resistant to adverse environmental conditions
  • Working temperature from -30°C to +60°C
  • 230 Vac, 50 Hz power supply
  • 12 mA supply current during measurement

Overall, the QuakeLogic QL-CA1I220 Thresholds Overshooting Warning Station provides a compact and reliable solution for threshold-based alarm monitoring, relay output control, and field warning applications.

For this reason, it is a strong choice for wind alarm systems, level alarm systems, environmental monitoring stations, and sensor-based safety warning installations.
