This input is compatible with all turbine flowmeters series TM and those instruments that

provide a magnetic pickup type output whose voltage is between 30 mVpp and 10 Vpp.

Higher values can damage the equipment.

The input impedance is 2 k. It has a protection for limiting the voltage applied to the

circuit consisting of two diodes in parallel and two 100  resistors.

The pulse output operates in repeater mode. It gives a pulse for every input pulse or for

each turbine signal period.

The pulse output is opto-isolated. The terminals are the collector and emitter of a NPN

bipolar transistor.
