The NetGuardian 224A monitors 24 discrete alarms and reports events to a Master Station, such as the T/Mon LNX, via LAN. 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.
The NetGuardian 224A features DPS Telecom's user-friendly Web interface for convenient configuration and monitoring. Other features include real-time Clock (RTC), single -48VDC using RIA connector, a GigE Fiber port with SFP Sockets (ordering option) and 12 Port 10/100/1000 BaseT LAN switch (ordering option).
