LTC391AE01 HIEE401782R0001 High speed Counting Module  

Product Manual：

LTC391AE01 HIEE401782R0001 is a high-speed counting module of ABB excitation system, which collects pulse speed signals to complete speed measurement.

1. High speed pulse acquisition, adapted to encoder speed signal
2. Channel photoelectric isolation to resist on-site electromagnetic interference
3. High counting accuracy, achieving real-time measurement of unit speed
4. Equipped with signal anomaly detection and output fault alarms
5. Slot rack installation, docking system backplane bus
6. Support orthogonal pulse signals and adapt to multiple encoders
7. LED status light, visually viewing the working status of the channel

8. 24V DC power supply, low module power consumption
9. Hardware filtering, filtering out on-site interference pulses
10. The board is equipped with a protective coating to prevent dust and moisture
11. Fast signal response, meeting the real-time requirements of excitation speed regulation
12. Upload data to the main control board and participate in excitation regulation calculations
13. Modular design, convenient replacement of spare parts
14. Anti vibration and shock resistance, suitable for the working conditions of power plant control cabinets
15. Complies with EMC standards and supports long-term continuous operation

LTC391AE01 HIEE401782R0001 is commonly used in the UNITOL excitation system of generator sets, providing speed feedback signals to support excitation regulation.
