Core functions
Electrical isolation anti-interference: Use optocoupler to cut off the ground loop between the field equipment and the PLC, avoiding common-mode noise interference caused by industrial site motors, frequency converters;
Weak signal amplification and shaping: Pull up the low-amplitude weak pulses from encoders and sensors, regularize the waveform, suitable for long-distance cable transmission;
Pulse multiplex splitting: Split a single input pulse into multiple synchronous outputs, enabling one encoder to simultaneously transmit signals to the PLC, industrial control instruments, and upper computer;
Level adaptation: Compatible with NPN/PNP, TTL type pulse signals, suitable for most industrial incremental encoders.
Typical application scenarios
Preprocessing of signal from machine tool spindle, conveyor line speed encoding;
Expansion of high-speed pulse acquisition for ABB complete PLC system;
Position closed-loop control of industrial robots, automation production lines;
Low-speed pulse detection for valves, rollers, multi-device synchronous sampling scenarios.
