Analog input module for a programmable logic controller, the analog input module having an input circuit with terminals for accepting either a single voltage range or a single current range from process control sensors. The chromium concentration often reaches values of more than 30%. The architecture of such neuromorphic engines is optimal for high-performance parallel processing of spiking networks with spike-timing dependent plasticity. The spool is moved into a specified selection region among a plurality of selection regions by the conversion mechanism and the arm member. The base portions of the contacts are held in the corresponding slots.
