The HIMA F3316 is a Safety Systems Input Module designed specifically for high-integrity safety applications in process industries. Manufactured by HIMA, a global leader in safety automation solutions, this module forms a critical part of a fail-safe control system used to monitor field input signals such as contact closures, switches, or digital sensor outputs.

The F3316 ensures reliable detection and transmission of digital inputs to the safety controller under all operating conditions. It is engineered with rigorous attention to signal integrity, fault detection, and system diagnostics, making it suitable for Safety Integrity Level (SIL) 3 systems as defined by IEC 61508.

Its robust design, paired with seamless integration into the HIMA HIMax and HIQuad platforms, enables the F3316 to deliver secure, redundant, and error-checked communication for critical operations where failure is not an option.
