Product Introduction
The HIMA F3349 Digital Output Module is a high-reliability safety component specifically designed for critical control functions in safety-related automation systems. As part of HIMA’s renowned HIQuad system platform, the F3349 module offers fail-safe, isolated digital output channels, ensuring safe actuation of field devices such as relays, solenoids, contactors, and indicator lamps.
With 8 independent output channels, each individually monitored and protected, the module meets SIL3 requirements under IEC 61508, making it ideal for deployment in emergency shutdown systems (ESD), burner management systems (BMS), and other safety-critical processes. The F3349 also features extensive diagnostics, including short-circuit detection and open load monitoring, which enhances operational safety and system availability.
Designed for rugged industrial conditions, the F3349 ensures reliable performance across a wide temperature range and is built for DIN rail mounting in a modular safety architecture.
