Main Functions
32-Channel Digital Signal Acquisition

The module receives up to 32 discrete input signals from field switches, sensors, and proximity detectors, converting their states into digital information for the control system.

Pulse Counting

The module supports pulse counting for applications such as equipment operation monitoring, production counting, and speed-related signal acquisition.

Input Filtering

Configurable input filtering helps reduce interference and prevents false signal transitions caused by electrical noise or contact bounce.

Latching Function

The latching option allows input events to be retained for monitoring and processing by the control system.

Line-Fault Detection

The module supports open-circuit and short-circuit detection. Additional resistors are required when using switch inputs for line-fault monitoring.
