K121: Universal Converter (mA, V, Ohm, RTD, TC) Isolated Loop Powered

K121 supports all standard J, K, R, S, T, B, E, N thermocouples (EN 60584) and Pt100, Pt500, Pt1000, Ni100 thermoresistances with 2, 3 or 4-wire connection as input. K121 also accepts voltage signals with scales ± 30 V and ± 150 mV and current (± 24 mA). The instrument also acquires input from a potentiometer with resistance between 500 Ω and 10 K Ω and resistances up to 1760 Ω. K121 features a reduced response time of just 140 ms for current and voltage input and less than 620 ms for other inputs. The accuracy class is 0.1% and the measurement conversion is 16-bit. K121 is ATEX II 3G Ex nA IIC T4 Gc X (gas) and II 3D Ex tc IIIC T135°C Dc X (dust) certified.
