Honeywell 05701-A-0330 System 57 High Integrity Safety Relay Output Card (SIS ESD Interlock Module)
Manufacturer: Honeywell Process Solutions
Model: 05701-A-0330 (System 57 Series Safety I/O Card)
Matching System: Honeywell System 57 High Integrity SIS Safety Interlock System; Not compatible with TDC3000 / Experion PKS C300 DCS
Type: Rack-mounted 8-channel safety relay output card, SIL2 certified per IEC61508, fail-safe design, heavy-duty SPCO relay contacts onboard
Core Function: Convert safety logic commands from System57 controller to hard relay contacts; drive ESD shutdown valves, alarm horns, strobe lights, exhaust fans, safety interlock loads; per-channel circuit self-diagnosis, contact wear monitoring, open/short fault feedback to safety CPU; applied in refinery, power plant, offshore platform SIS safety cabinet
1. Product Overview
05701-A-0330 is the core safety output module of Honeywell System 57 SIS platform, dedicated to safety instrumented system emergency interlock execution. It integrates 8 independent industrial safety SPCO relays directly on PCB, no external FTA relay terminal board required; front orange terminal block directly connects field safety equipment loads.
Adopts fail-safe de-energized trip logic: when card power loss, communication failure or internal circuit fault, all relays drop to safe state (normally closed contact closed) to trigger emergency shutdown, meeting safety instrument system single fault tolerance requirements.
Full channel self-test function: real-time monitor relay coil circuit, contact open/short, load loop fault, fault signal uploaded to System57 safety controller for alarm recording. Dual redundant communication bus with main controller to avoid single point of failure.
24VDC backplane power supply, wide temperature industrial hardware, heavy 10A/250VAC contact rating can directly drive valve solenoids, sound-light alarm devices without intermediate relays. Standard System57 3U rack slot installation, hot-swappable for online maintenance without full rack shutdown.
