A resistance monitoring solid state circuit distinguishes between a minimum high resistance condition and a maximum low resistance condition by current mode switching of a pair of transistors the switching contol voltages of which are established by bias resistor networks forming legs of a bridge, with the monitored resistance in one leg, the transistors switching current flow into one or the other of two logic signal generating paths that include opto-isolators for electrical isolation from utilization circuitry.
