The PR Series pilot relays are ideal multi-voltage input pilot duty relays that mount to existing panels to control loads. External enclosures are not required making them ideal for interfacing loads with building automation control systems. Featuring the highest output in the smallest package, integrated current sensing, and a secure tamper resistant HOA.
