The Ammeter measures the current in signalling systems, trains or other railway products.
The basic idea behind the product is to make a generic failsafe electronic ammeter that connects to a wire and transmits the measured currrent value to an interlocking system or a train computer.
Case 1: Interlocking controlling object
Case 2: Interlocking energize relay. Optional current leak detection
The current is measured with built-in resistors.
Two independent microprocessors (1 and 2) compile telegrams to a serial line that can be read by the Railway system.
Internally, the Ammeter continuously performs a self-test.
