  • TypeWelding Supplies
  • Monitors four zones simultaneously for temperature, humidity and water presence
  • Local LCD display with tamper-proof lock shows real-time readings clearly
  • Eight-event memory logs time and date of each incident
  • Programmable alarm delay up to 120 minutes per zone
  • Operates on 24 V DC power at 120 mA

Four-zone environmental monitor

The Winland Electronics EA400-24 monitors up to four separate zones for temperature, humidity, or water presence. It provides local visual and audible alerts through an integrated piezo buzzer and connects to security panels for real-time incident notification. The unit operates on 24V DC power and features an LCD display with tamper-proof lock settings.

Facilities needing multi-point alerting

This device suits server rooms, warehouses, or cold-storage areas that require simultaneous monitoring of four distinct locations with programmable alarm delays up to 120 minutes per zone. It is not intended for direct placement inside freezers or coolers; wired sensors must be used instead. Buyers needing more than four zones or integrated wireless connectivity should consider other solutions.

Sensor range and relay capacity

Each zone accepts sensors covering a low-limit to high-limit adjustment range of -58 to 302°F (-50 to 150°C) with an offset adjustment of ±9.0°. The unit itself operates between 32 and 122°F in non-condensing environments. Four configurable Form C (SPDT) alarm output relays provide auxiliary contacts for external alarms, while an 8-event memory logs incidents with time and date stamps.

Questions about this item

What external sensors do I need to connect to the four zones of this EA400-24 monitor?

The EA400-24 has no on-board temperature sensor, so you must wire a compatible sensor to each of the four zones you want to monitor.

Will the 24 V DC power supply from my existing security panel run this unit?

Yes, the EA400-24 requires 24 V DC at 120 mA, which matches the output of many security-panel power supplies.

How can I verify the EA400-24 is logging events correctly after installation?

Check the LCD for the 8-event incident memory; each entry should show the zone, time, date and whether the reading exceeded the programmed high or low limit.
