Labor costs commonly range from $50 to $450 per job for relay installs, depending on complexity. Buyers typically pay a range for relays, and cost is driven by relay type, coil voltage, contact rating, and packaging. This guide presents practical price estimates in USD, with low–average–high ranges and real-world factors that affect total cost. In general, a basic PCB relay may cost $1–$5 per unit when bought in small quantities, while higher-end industrial relays with protection features can run $50–$200 each.
