HIMA F3322 is a 16-channel digital output module designed specifically for safety-related industrial automation applications in control systems such as the HIMA HIQuad safety system. Used widely in heavy industries like chemical processing, energy production, and manufacturing automation, the HIMA F3322 provides reliable control outputs to actuate safety devices including valves and alarms. It addresses critical safety challenges by delivering fail-safe switching of loads up to 500 mA per channel (resistive or inductive), supporting essential safety functions in environments requiring high availability and fault tolerance.
The HIMA F3322 module operates within the overall architecture of HIMA’s Programmable Electronic Systems (PES), fitting into an IO subsystem to output signals directly to external devices. This makes it a key component in transmitting safety commands within a larger distributed control strategy. Its 16 independent channels allow simultaneous control of multiple outputs, making it flexible for complex process safety applications. The module supports lamp loads as well and ensures no output signal in case of supply breaks, which enhances fail-safe performance.
This digital output module features a compact, standardized 4 TE width design suitable for mounting in dedicated subracks with up to 10 modules per rack. It incorporates robust short circuit proof outputs, a current limiter triggering above 550 mA, and safety isolation for reliable long-term operation. The HIMA F3322 is engineered to manage up to 8 A total output current simultaneously with appropriate module fusing, and is designed for operation at typical industry power levels (5 V/24 V DC) with diagnostic capabilities to aid maintenance.
The module’s compatibility with HIMA HIQuad and HIQuad X series control systems makes it valuable for engineers integrating comprehensive safety instrumented systems (SIS) that meet SIL standards. It delivers high dependability in harsh industrial environments by integrating safety isolation and enables easy replacement and maintenance without impacting system uptime.

Installation of the HIMA F3322 requires adequate space in a control cabinet with proper subrack for secure mounting. Grounding and electrical isolation should be verified to ensure system safety and reduce noise interference. It is important to keep free clearance for ventilation and easy access to connectors for maintenance. Maintenance routines should include regular visual inspection for damage, verifying the absence of faults via signal diagnostics, and updating firmware through compatible system software to sustain safety and functionality.
