- Functional Features:
- 1 input and 8 output channel design realizes one-to-many digital signal distribution, which can transmit a single field digital signal to multiple PLCs, HMIs or other control equipment at the same time, simplifying the system wiring structure and reducing the number of field sensors.
- 2500 VAC high-voltage electrical isolation between input and output and between output channels effectively isolates industrial field electromagnetic interference, prevents ground loop interference and fault spread between different equipment, and ensures the stability and reliability of digital signal transmission.
- Built-in RC low-pass filter with 500 Hz filtering frequency filters out high-frequency interference pulses in the industrial field, avoiding misoperation of the receiving equipment caused by interference signals, and improving the anti-interference performance of the digital signal transmission system.
- Fast signal response time (≤2 ms) ensures real-time transmission and distribution of digital signals, meeting the high real-time requirements of industrial control systems for digital signal transmission.
- NPN open collector output type with high rated output current (1 A per channel) can directly drive small industrial actuators such as indicator lights and relays, and can also be connected to various standard digital input interfaces of PLC and HMI, with strong compatibility.
- Support both NPN and PNP type input signal configuration, adapting to different types of field digital sensors and switching devices, with high system adaptability.
- Built-in overvoltage, reverse polarity and output short-circuit protection functions, effectively protecting the module and connected equipment from damage caused by abnormal power supply and output faults, and the protection functions are self-recovering.
- LED status indicators for power on (green), input signal (yellow) and output signal (red for each channel) realize visual monitoring of the entire signal transmission and distribution process, facilitating quick troubleshooting of signal faults.
- Narrow width compact design saves the installation space of the industrial control cabinet, and the standard DIN rail mounting design is convenient for on-site installation and disassembly, suitable for dense installation with other industrial modules.
- Application Scenarios: Widely used in industrial control systems that require digital signal conditioning, isolation and distribution, such as automobile assembly line multi-station signal sharing, packaging machinery multi-equipment signal linkage, power distribution room automation system signal distribution, and intelligent building lighting control system signal transmission. It is also applied in industrial field with multiple control equipment sharing a single sensor signal, solving the problems of signal interference and wiring complexity in signal distribution, and is suitable for all industrial occasions that require one-to-many digital signal distribution and anti-interference processing.
