It is equipped with 2 user-defined analog channels with 4 user defined thresholds per channel. The analogs terminate to convenient RJ45 connectors. There is 1 connector per analog channel and each input supplies +24Vdc to power your sensor if needed. Each analog may be configured for either -90 to 90 voltage range or 4-20 mA using field selectable shunt.
The NetGuardian 224A includes 24 discrete alarm inputs, 2 general-purpose relay outputs, and 2 general-purpose analogs, plus integrated battery voltage monitor. The unit also comes with 1 RS232 serial port for future use.
