The Omron KM20-CTF-50A with Controllers CT 50A Primary Current is a compact, standalone current sensor that is designed to measure electrical current in a wide range of applications. It features a range of 50 A, a small size, and a durable construction. It is accurate to 0.2 percent of the reading for current values up to 20 A, and up to 0.5 percent of the reading for values between 20 A and 50 A. The KM20-CTF-50A can be used in an expansive variety of conditions, from the workbench to a harsh industrial environment. The device is equipped with insulation-resistance protection, waterproofing, vibration resistance, and surge protection. Its power and signal lines are variously rated for 100V, 24V, or 5V. Additionally, two digital outputs are available for monitoring current (PTC) and overload events (Error, OVLC, SC).
