The KL-M4701 multi-signal processing module is a product with 8 channels of analog signal, 1 channel of frequency signal, and 1 channel of switch signal counting acquisition function. It uses high-precision devices, ensuring high accuracy and good linearity. At the same time, complete protection measures are taken in power supply, communication, and input parts to make the module safer and more stable in application. This product is suitable for sensor signal acquisition and data transmission between sensor and upper computer.
The KL-M4701 multi‑signal processing module provides 8 analog, 1 frequency and 1 counter input channels for sensor data acquisition. It supports RS‑232 or RS‑485 communication and includes a relay for sensor power control.
The manual covers technical parameters, mechanical installation, terminal definitions, wiring diagrams, communication configuration and additional notes such as alarm settings and data storage procedures. This manual is written in Chinese.
