Product Description

The Triconex DI232 Digital Input Module is a high-density digital input interface engineered for Tricon Triple Modular Redundant (TMR) Safety Instrumented Systems (SIS). It provides 32 discrete input channels, forming the critical interface between field-level digital devices and the Tricon safety controller in high-availability applications.

Designed around a 24 VDC input architecture, the DI232 continuously monitors the status of field signals from devices such as pressure switches, limit switches, and push buttons. Leveraging the Tricon TMR architecture, the module performs hardware-based voting, ensuring that single-point failures do not compromise safety functions. Advanced signal conditioning and isolation techniques minimize electrical noise and prevent false triggering in harsh industrial environments.
