K121

K121, K121-C

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

K121 is a performant universal converter able to manage all analog signals (mA, mV, V, PT100, Pt1000, Pt500, Ni100, TCs, Ohm) and convert / isolate it into 4..20mA loop powered signal. The output mode (normal/inverted), scale overrange, output in case of fault sensor are selectable parameters available by PC software. A 2-way galvanic isolation among input // output circuits assures the integrity of your datas. K121 is ATEX compliant product II 3G Ex nA IIC T4 Gc X (gas) II 3D Ex tc IIIC T135°C Dc X (dust).
