K121 is a versatile universal converter capable of processing all types of analog signals. It has multiple input types including Cu50, Cu100, Pt100, Pt500, Pt1000, Ni100, Ni120, Ni1000, and TC J, K, R, S, T, B, E, N, L. Its input impedance is 10 MΩ for thermocouples, resistance temperature detectors, and voltage.
Potentiometers have an input impedance of 10 MΩ and a range of 500 Ω..100 kΩ. The voltage input range is -150..+150 mV with an input impedance of 10 MΩ and -30..+30 V with an input impedance of 200 kΩ. The current input range is -24..+24mA with an impedance of 40Ω. The resistance range is 0..+400 (1.760) Ω. The maximum power dissipation of K121 is < 660 mW. It has programmable rejection for 50 or 60 Hz and an operating temperature range of -20..+65°C.
K121 can be used in various applications that require the processing of analog signals such as industrial control, instrumentation, and measurement systems. It comes with 8 spring clamps for easy and secure connection of wires. K121 can accurately convert any analog signal into a digital signal.
Overall, K121 is an excellent sensor for applications that require accurate data processing. Its versatility in processing various input types and programmable rejection rates make it highly adaptable to a wide range of applications.
