Discrete Signal Input Module DI48-STM for AVR Systems

The unit is used to transmit the state of 48 discrete signals to automatic excitation regulators of synchronous machines of AVR series. LEDs are used to indicate the state of the signals. A highly reliable CAN interface is used to exchange information with the regulators.

Digital filtering is used to protect against interference. The maximum lag time for protection signals is 3 ms and 15 ms for other signals. Rated voltage is 24 or 48 V.

Rated current is 10 mA. Input/output test voltage is 2000 V. The unit is mounted on a DIN-rail.

Warranty period - 36 months from the date of shipment to the factory Electrosila.
