Analogue sensors
Analogue sensors are connected to connector 6 and 4 (input I9 and I10). Pin 5 is the current loop's plus connector
and pin 4 is the current loop's minus connector. Pin 2 is not used.
Power supply
The power supply SM6 is connected to connector 2 with 24 VDC on pin 1 and 0VDC on pin 3. Pin 2, 4 and 5 are
not used.

Pulse sensor
To measure motion, speed and position a pulse sensor (SM5/SM7) is connected to Smart Logger. The pulse
sensors have a resolution of 0.1 mm, i.e. they send 10 pulses/mm. Based on incoming pulses Smart Logger
calculates at which position the sensors are and at what speed they move.
