The NNR220A is a liquid level controller designed for high and low level monitoring in various applications. It operates on input voltages ranging from 24 VAC to 220 VAC and features a sensitivity adjustment between 4.7 k,Ѷ and 47 k,Ѷ. The controller supports one, two, or three probe operation and utilizes a single pole double throw (SPDT) relay rated for 10 Amps. The device has a maximum switching voltage of 250 VAC and can handle a maximum load of 10 AAC resistive or 1 A DC inductive. It is equipped with a mechanical life of 30 million operations and an electrical life of 200,000 operations at a 2200 VA resistive load. The operating temperature range is from +14¬8F to +140¬8F (-10¬8C to +60¬8C), making it suitable for various environments. For optimal performance, it is recommended to use shielded cables for the probes and to avoid running probe cables alongside other wires. The NNR220A is UL listed and CSA recognized, ensuring compliance with safety standards.
