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 kΩ. It has a protection for limiting the voltage applied to the
circuit consisting of two diodes in parallel and two 100 Ω 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.
