ELECTRICAL CHARACTERISTICS
0~20mA / 0~10V can be selected for analog output sensors. Temperature range for digital output Enda Sensor is -40~125°C
Temperature input range
Humidity input range
0~20mA / 0~10V can be selected for analog output sensors. Humidity range for digital output Enda Sensor is 0~100 RH
When thede vice is in current measurement mode, the input impedance is 10 . Therefore voltage input should not be connected to the device while
in current mode. Otherwise the device will deteriorate. If it is necessary to switch from the voltage measurement mode to the current measurement
mode while the device is running, It must be removed and the n changed to one of the input type current measurement modes.
Ω
Max. 12VDC 30mA.
SSR Output
KEEP AWAY device from exposed to corrosive, volatile and flammable gases or liquids and DO NOT USE the device in similar hazardou s
locations.
Avoid any liquid contact when the device is switched on.
DO NOT clean the device with solvent (thinner, gasoline, acid etc.) and / or abrasive cleaning agents.
