Built‑in function
760ISB‑A single‑loop PID controller executes closed‑loop regulation for pressure,flow,temperature and liquid‑level process loops. It supports local manual set‑point modification and full PID parameter on‑site adjustment. Bumpless auto‑manual switching avoids output impact during mode change. Metal shield housing suppresses industrial electromagnetic interference,ensures stable loop running for continuous‑process sites. LED status indicators help technicians rapidly locate power and communication faults for on‑site troubleshooting.
Product Brief
760ISB‑A belongs to Foxboro 760 Series legacy control spare‑part family,obsolete original automation component. It shall be installed inside matching instrument rack with correct 4‑20mA field signal wiring. Widely used for original Foxboro automation equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation
