Technical Specifications 4 independent inputs: 50 mV–30 V AC, 10 Hz–20 kHz; 4 24 V DC square wave outputs; Supply: 24 V DC ±10%; per-channel signal loss detection; Operating temperature: -40 °C to +70 °C; Enclosure: IP20.
Functional Features Four channels operate independently; per-channel signal loss alarm; unified power supply; centralized mounting; wide input amplitude tolerance.
Application Scenarios Multi-unit power plant speed monitoring, multi-redundant speed sensing systems, gearbox multi-point speed detection, integrated monitoring systems.
Performance Parameters Channel-to-channel crosstalk: < -60 dB; per-channel frequency accuracy: ±0.02%; signal loss response: < 10 ms.
Material Composition Flame-retardant plastic housing; multi-channel conditioning PCB; isolation devices; screw terminals.
Structural Characteristics Standard rack plug-in module; front panel 4-channel status LEDs; rear panel multi-circuit terminal block.
Working Principle Four independent conditioning channels filter, shape and isolate input speed signals respectively, output standard digital speed signals, with all channels operating independently without interference.
Installation Requirements Install in control cabinet; route sensor cables separately per channel; unified grounding; label each channel with measuring point.
