Input Module (I) (1) Inputs. (2) Connection to calculation and connection module (CU) control box.Input module (I) is used to sense various functions of the harvester head. For example, Input module (I) can sense input signals from the diameter sensors and the length sensor. Input module (I) can receive various types of input signals.
Maximum of 8 digital input signals
Maximum of 8 enumerators
Maximum of four inputs from the pulse sensor
The input can sense the direction of the pulse sensor.
Maximum of 4 analog inputsInput module (I) is controlled from the calculation and connection module (CU) via a CAN bus connection. See Table 1 for the diode functions.
