Features

A humidity and temperature measuring solution for ATEN PG PDU series
Precise relative humidity accuracy: ±7.5 % RH, 30 – 70 % RH; ±15 % RH, 15 – 40 % RH, 70 – 90 % RH
Highly accurate temperature measuring: ±1 °C (Max.), 10 – 40 °C; ±1.5 °C (Max.), –10 – 10 °C, 40 – 75 °C
Supports up to 8 daisy-chained devices
Multiple interfaces to broaden applications – – 1 x RJ-45 input port, 1 x RJ-45 output port, and 1x RJ-11input port support connection with PG PDU series and EA1140 / EA1240 / EA1340 environmental sensors – 1 x terminal block supports EA1440 / EA1441 / EA1442 door sensor and EA1540 capacitive leakage sensor
Meets flexible installation purposes – – Included 1.5 m RJ-45 cable for ideal location placement – Contains a magnet for sticking to metallic surfaces – Included rack mount kits enable quick installation inside racks
Overload protection prevents overheating of the protected equipment
LED indicator is visible through the enclosure
Prevents device malfunctions thanks to early detection in case of overheating / excessive humidity
Suitable for applications that require precise measuring, such as server rooms, data centers, hospitals, smartfactories, and green offices

LEDs

LED Indicator: [Solid]: EA1640 is in working mode [Fast Blinking (for 2 minutes)]: EA1640 receives the command “FindMe”. [Slow Blinking (for 10 seconds)]: Over-current protection (OCP) is triggered, and the sensor(s) connected to EA1640 is going to power off. [Slow Blinking]: Firmware upgrade of EA1640 is in progress.
Note: For some of rack mount products, please note that the standard physical dimensions of WxDxH are expressed using a LxWxH format.
