✅Core functionality

On site switch quantity collection collects 24VDC on-site on-off signals, with photoelectric isolation, and sends sensor/switch signals to PLC CPU logic processing; Supports NPN drain type and PNP source type wiring logic, suitable for the vast majority of DC sensors.

4 isolated groups (8 points per group) with 4 independent common ends, isolated between groups; Different groups can be connected to different reference potentials to suppress on-site interference, and a fault in one group will not affect the other channels.

High speed signal capture (core strength): The hardware response is typically 1ms, and the software can be configured to filter 1/3/7ms. It can capture short pulses, high-speed proximity switches, and short-term jump signals that are lost by ordinary low-speed input cards. This module can reliably capture them.

Local indication of channel status with independent LED for each channel, allowing for quick on-site detection of signal presence without the need for computer software installation for troubleshooting.

System diagnosis of backplane communication abnormalities and external power supply abnormalities can be reported to the PLC diagnostic buffer for easy fault location; Adapt to Proficy ME/LogicMaster90 software configuration hardware address and filtering parameters.

High density cabinet space with 32 points occupying only 1 I/O slot, suitable for devices with multiple input points and tight control cabinet space; Support installation of local backplane, expansion backplane, and remote I/O backplane.

🛠 Typical on-site applications

A large number of photoelectric and proximity switches are used for assembly lines and sorting equipment, as well as for material placement, blocking, and detection; In high-speed sorting scenarios, it is necessary to capture brief signal pulses and leverage the advantage of 1ms high-speed acquisition.

Magnetic switches, limit switches, safety doors, emergency stop feedback, button signal acquisition for machine tools, stamping, and assembly equipment cylinders; A large number of DI points, with 32 points per card, reducing the number of modules.

Packaging and printing equipment detection photoelectric, material level switch, turntable position feedback, workstation status feedback.
