MODEL 906 with CODE (ED8) Preinstallation for parameterizable special module (PSM) 

Discrete inputs and outputs 

The PSM control unit has various discrete inputs and outputs. The inputs are debounced and stored as a signal in the signal pool. The logical status "1" means that the respective switch at the input is active, irrespective of whether the input is positive-active or ground-active.

The individual outputs are assigned signals by means of parameterization. In the case of outputs with special functions (half-bridge) and pulse width modulation (PWM), additional information regarding their use is required. If the respective signal is 1 (active), the output is activated. Activation is performed irrespective of the switched level (low-side or high-side).

Further information on the inputs, e.g. internal wiring, can be found in the "Technical data" documents.

The "PSM interfaces" comprise the following interfaces:

• "Inputs interface"
• "Outputs interface"
• "CAN interface"
• "Fleet management system interface"
