AMETEK 5200-LF1 Solid State Relay

The AMETEK 5200-LF1 Solid State Relay is a low-sensitivity input device in the 5200 series, designed for electrode-driven control of AC line loads in BW Controls pump-start and tank-electrode applications. It belongs to the 52-110100 series and uses a fixed sensitivity resistor (R1) for its input, enabling direct operation from low-level electrode signals in tanks or related sensing setups. The LF1 designation identifies the low-sensitivity input variant, with an available 5200-LF1-OC option for overload/relay configurations. This relay accepts 115 V or 230 V AC line voltage at standard 50/60 Hz, providing solid-state switching of AC loads without mechanical contacts. Typical operating characteristics for the 5200 family note a broad ambient range, including -40°F to +180°F (-40°C to +82°C), making it suitable for industrial environments. Applications commonly include pump start/stop control and tank electrode sensing in water treatment, processing, and similar process-control systems where reliable, contactless switching is required. The 5200 line is designed for direct integration with AMETEK/BW Controls equipment, offering a compact, serviceable solid-state alternative to traditional relays while maintaining compatibility with existing electrode-driven control architectures.
