Winland EA400-24 EnviroAlert Zone Critical Condition Monitoring of Temperature, Humidity and Water, 24VDC

Here is a rephrased and industry-focused version of your text:

• Operate up to four sensors simultaneously with a clear LCD display and secure, tamper-proof settings.
• Maintain a history of 8 event incidents with timestamps and utilize an auxiliary output relay for a local audible alarm (not included) with a silencing feature, 10-minute timer, and programmable alarm delays up to 120 minutes for each zone.

• Excludes an onboard temperature sensor.
• Operational temperature range of 32 to 122°F (0 to 50°C) in non-condensing conditions.
• Adjustable sensor-dependent limits range from -58 to +302°F (-50 to +150°C).
• Features 4 configurable Form C (SPDT) alarm output relays (N.O./N.C.) and 1 non-configurable auxiliary alarm output relay (N.O./N.C.).
• Device dimensions are 6.0" x 4.75" x 1.25" (15.24cm x 12.07cm x 3.18cm).
