Description
The 05704-A-0123 is a heavy-duty hex relay interface assembly designed specifically for the Honeywell System 57 series. As a key backend component of the 5704F four-channel fire control card, this assembly addresses the stringent requirements of multi-channel alarm outputs in complex industrial environments.
Applications
Oil Refineries: Links fire monitoring system to foam extinguishing and alarms.
Fertilizer Plants: Uses 6 relays for multi-level fire alarm linkage.
Fine Chemical Plants: Provides alarm outputs with lockout safety function.
Semiconductor Plants: Controls cleanroom sprinkler systems via high-density outputs.
Troubleshooting and Maintenance Recommendations
Troubleshooting: If the output circuit does not operate, check if the relay mode setting matches the external wiring (normally open/normally closed). An Engineering Card can be used to test the operation of each relay without affecting input monitoring.
Maintenance Recommendations: It is recommended to perform load-bearing function verification on all 6 relays during regular annual inspections to prevent contact sticking. Keep terminal screws tight to ensure the contact performance of the 14 AWG wires under high load operation.
FAQ
Q: What type of contacts are the 6 relay outputs of the 05704-A-0123?
A: It has 6 independent SPCO relays with NO, NC, and common terminals.
Q: What is the maximum load current of the 05704-A-0123?
A: It supports up to 5A non-inductive load at 110/250 VAC or 32 VDC.
Q: Can the 05704-A-0123 be manually reset after an alarm?
A: Yes, it supports latching mode until manually reset by the system.
Q: What is the power consumption of the 05704-A-0123 under full load?
A: Typical consumption is 1.7 W, and it stays below 2.4 W at maximum load.
Q: What wire size is supported for field wiring on the 05704-A-0123?
A: It supports up to 2.5 mm² (14 AWG) industrial wiring.
