● C_IO: capacity between input and output (in the event of output stage: C_IO is valid if the output stage is turned off)
● I_Out: output current
● I_Out_SC: output current
● I_Leak_Off: loss of current if the ECU is no longer powered
● I_Out_Diag: loss of current with ECU powered, but PS no longer powered. This parameter defines the ability of the hardware to provide a dia-
gnostic current. The actual existence of the diagnostic current depends on the software configuration
● V_OC: voltage between CON_PIN and ground with open circuit
● V_THR: open load threshold voltage
● V_Out: output voltage
● V_Out_High: output voltage, HIGH level
● V_Out_Low: output voltage, LOW level
● R_ON: output resistor ON
● E_Clamp: energy at the output terminals
● V_Out_Clamp: voltage at the output terminals
● R_Load-Diag: Maximum diagnosable load resistance
● t_Fall: signal fall time from 90% to 10%

2. Separation diode REQUIRED
3. Interface responsibility of the designer of the processor
4. Signal processor
The bodybuilder must install a special separation diode so as not to lower the V
ON
voltage.
The designer of the signal processor must ensure an input interface equal to that represented with a max. voltage V
DC
of 5 V and "pull-up /
pull-down" so as not to lower the voltage V
ON
and to raise the response time set by the vehicle interface.

The signals to the Multiple State Switch may also be simultaneous to requests coming from the Expansion Module through CAN open
(object 0x2001, sub 0x0C) or through activation of "PTO1/PTO2/PTO3 Memo Speed". The highest value prevails in the event of contempor-
aneity.
