Product Introduction
The HIMA Z7136 Digital Output Module is a high-integrity, industrial-grade digital output interface designed for fail-safe automation applications in critical infrastructure. As part of the HIQuad safety system family, it is widely implemented in sectors such as oil & gas, petrochemical, power generation, transportation, and industrial automation where safety and reliability are paramount.
This module provides 16 digital output channels, specifically engineered to actuate relays, valves, contactors, and signal indicators with complete safety assurance. With built-in fault diagnostics, channel isolation, and compatibility with SIL 3-rated systems per IEC 61508, the Z7136 ensures long-term operational reliability in safety-related automation.
Each output is independently monitored for wire breaks, short circuits, and output voltage levels, making it a perfect fit for safety-critical installations. The Z7136 supports hot-swapping, enabling maintenance without system shutdown, thus minimizing downtime in continuous process environments.
