VIPA 321-1BL00 Digital Input Interface Module

The VIPA SM321 321-1BL00 digital input module delivers high-speed digital signal acquisition for VIPA PLC systems, enabling reliable collection of discrete field signals from sensors, pushbuttons, proximity switches, and limit switches that drive machine operation. As part of the SM321 series, this modular digital input module is designed for control cabinet installation within VIPA’s PLC architectures, offering compatible input channels for industrial automation panels across manufacturing lines, packaging equipment, conveyors, and process automation machinery. With industrial-grade construction and suitability for continuous-duty operation, the 321-1BL00 supports discrete field device inputs and sensor/switch integration, delivering the speed and reliability needed for real-time status reporting to the controller. It is commonly used in OEM equipment and automation projects where sensors, pushbuttons, proximity switches, and limit switches must communicate status information to the VIPA controller, enabling safe start/stop conditions, fault detection, and coordinated process control. Common replacements include VIPA 221-1BH10, Siemens SM321 Digital Input Module, and Allen-Bradley 1769-IQ16.
