Loop powered isolator / universal converter (mA, V, Ohm, RTD, TC)

K121 supports input signals from Cu50, Cu100, Pt100, Pt500, Pt1000, Ni100, Ni120, Ni1000, TC J, K, R, S, T, B, E, N, L, potentiometer, voltage signals with ± 30 V and ± 150 mV scales and current (± 24 mA). The instrument also acquires potentiometer input with resistance between 500 Ω and 10 K Ω and resistances up to 1760 Ω. K121 features a reduced response time of only 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 to 16 bit. K121 is ATEX certified II 3G Ex nA IIC T4 Gc X (gas) and II 3D Ex tc IIIC T135°C Dc X (dust).
