Abstract (en)
[origin: EP1261120A1] The arrangement has a first current source (ST1), a unit for electrical isolation, an intermediate resistance (RZ) and a second current source (ST2). The unit for electrical isolation and the intermediate resistance are both connected between the two current sources. Each current source contains a transistor (T1,T2), a resistor (RS1,RS2) and a Zener diode (S1,S2). AN Independent claim is also included for a parallel input/output unit for railway signaling.
