Features:
- Four separate output channels allow flexible control of multiple field devices from a single module.
- The 2500 Vrms isolation enhances protection between control circuits and external loads.
- SIL 2 and SIL 3 capability supports applications requiring high operational integrity and dependable response.
Industrial safety systems often require dependable interfaces between controllers and field equipment, and HIMA F3421 fulfills this role efficiently. The module converts low-level control signals into relay outputs capable of driving external devices. Four independent channels provide flexibility when several actuators or alarms need to be controlled simultaneously. DIN rail mounting also simplifies cabinet integration.
Signal amplification is one of the key advantages of HIMA F3421. A 24 V DC input activates normally open relay contacts with switching capacities reaching 250 V AC or 30 V DC at up to 10 A. In addition, 2500 Vrms isolation improves protection against electrical interference. Combined with humidity tolerance up to 90% RH and operation from -20°C to +60°C, the module is suitable for demanding environments.
HIMA F3421 is widely used within HIQuad and HIQuad X safety automation platforms. Typical installations include emergency shutdown systems, fire and gas protection systems, burner management systems, and high-pressure protection systems. Facilities involved in oil and gas production, petrochemical processing, metallurgy, and power generation rely on such applications to maintain safe and continuous operation. Through dependable relay amplification, HIMA F3421 helps critical processes respond effectively to abnormal conditions.
The F3421 HIMA 4-Channel Relay Amplifier Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
