The Winland EnviroAlert EA200 is a critical-environment monitoring device that provides visibility into two environmental factors simultaneously: ambient temperature from its onboard sensor, plus an additional factor of temperature, humidity, or water presence from a second, external sensor input. It features an easy-to-read LCD display, an 8-event incident memory with time and date, an auxiliary output relay for a local audible alarm, and an alarm silence feature with a 10-minute timer. Separate high and low limits can be set per zone, with alarm notification delivered via dry-contact relay to a connected alarm panel or local buzzer. This model runs on 12VDC power.
