HONEYWELL Q7800A1005 Universal Terminal Wiring Base

Product Description

HONEYWELL Q7800A1005 is a 22-terminal universal wiring subbase of Honeywell 7800 Series. It adopts plastic housing with double-sided terminal design for panel mounting. It is designed to match 7800 series relay modules and S7830A expanded annunciator. The subbase provides terminals for field wiring. Electrical connection is achieved by engaging bifurcated contacts with knife-blade terminals on the control relay module. Field wiring can be completed before installing the main control module, which simplifies commissioning, maintenance and module replacement. Knockouts are reserved on the back, top and bottom for conduit entry. Enclosure rating is NEMA 1.
