TDO-40 Signal Monitoring Block for Monitoring Up to 20 Discrete Signals

The TDO-40 unit is designed to control up to 20 discrete signals from "dry contact" type sensors (for example, air pressure gauges in the cable), control up to 20 two-wire lines with connected to them digital fingerprint sensors with the function of intrusion detection, indication of modes and alarm events, storage of information about the state of the monitored signals and its transmission to the monitoring centre by means of channel-forming equipment. TDO-40 unit provides transmission of information about the state of the monitored signals to the monitoring centre via RS-485 interface.
