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 12-bit 4-20 mA Input Adapter interfaces with any sensor providing a 4-20 mA signal to connect to smart sensor compatible HOBO stations. This adapter features both a non-switched input and a battery-saving switched input that extends the life of external batteries. It also provides a trigger signal for controlling power to attached external sensors, while offering digital filtering which improves measurement accuracy with 32 readings/sample and 60 Hz noise rejection.
