PILZ 312200 Digital Input Module With Carrier Unit

The PILZ 312200 PSSu E F 4DI Digital I Module With Carrier Unit is a four-channel digital input device from PILZ that ships with its carrier unit. The 4DI designation identifies four digital input channels, allowing a control system to receive binary signals from field devices. Model 312200 is the specific device in PILZ’s catalog, and the inclusion of a carrier unit indicates it is ready to mount as part of a larger I/O assembly. The PSSu E F portion of the model name is part of the product’s nomenclature and helps distinguish this unit within PILZ’s digital I/O lineup. This description reflects only the verifiable elements: brand, model number, digital input capability (4DI), and the carrier-equipped configuration. When integrated into an appropriate PILZ I/O system, this module serves as the input interface for signals from sensors and switches, enabling digital information to be read by a controller. As delivered, it provides the essential components needed for installation in systems that require four digital inputs and a carrier interface.
