Provides two channels of either 4-20 milliamp inputs or 0 to 20 VDC inputs and 12 volt excitation.
This option is chosen during U30 system configuration. Enables analog sensor input.
The 12-bit FlexSmart Analog Input Module for use with the H22-001 Energy Logger handles two single-ended input channels with user-configurable ranges of 0 to 20mA DC or 0 to 20 V DC which is suitable for 2.5-, 5-, and 10-volt sensors. Field wiring is 2- or 3-wire via screw terminals.
The Telaire 7001 handheld carbon dioxide sensor features patented Absorption Infrared technology. Each sensor measures CO2 and temperature and can calculate and display real-time ventilation rates. When combined with the HOBO U12 or ZW Series it can record CO2, and when connected to an analog input on a H22, RX3000, or U30 Series it can record temperature and CO2. The Telaire comes with an adapter but also operates up to 70 hours on 4 AA batteries (not included).
