The amplifier puts \u003cstrong\u003eone\u003c\/strong\u003e bridge signal on \u003cstrong\u003etwo galvanically isolated current outputs\u003c\/strong\u003e, so that a safety controller can check the two channels against each other.\u003c\/p\u003e\n\u003cp\u003eThis is a safety component, not a measuring instrument: the redundancy comes from the two outputs, not from higher measuring accuracy. If the channels deviate by more than 10 %, the controller takes the plant to its safe state.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003etest pulse input\u003c\/strong\u003e allows the measuring chain to be checked during operation: a 24 VDC pulse raises the current of channel B by 1 mA.
