1. Overview
GR-4C-AC230V is Honeywell GR series 4-pole miniature plug-in intermediate relay with 230VAC control coil. It adopts transparent flame-retardant shell, built-in red manual test button for offline contact simulation, and LED power indicator to display coil energization status in real time. The contact structure is 4CO (4 normally open + 4 normally closed), silver alloy contact material with stable conductive performance and long electrical service life. It can be plugged into the dedicated PGR-4C-E DIN rail socket base for cabinet centralized wiring, and supports matching AGR-MDL surge absorption module to suppress coil reverse electromotive force and protect upstream DCS/PLC DO modules. Widely used in power plant, petrochemical, water treatment and automation equipment DCS control cabinets for interlock logic, alarm signal and solenoid valve drive switching.
