Input Interface, PSM, Function - GF54.21-D-3001TSA
Model 907
with code ED5 (Parameterisable special module)
Inputs
10 multifunction inputs 01 to 10:
- 3 digital low-side active inputs, multifunction inputs 05 to 07
- 3 digital high-side active inputs, multifunction inputs 02 to 04
- 4 analog low-side active inputs, multifunction input 01, multifunction inputs 08 to 10
For the multifunction inputs, the pull-up resistors shown in the pictures cannot be manually switched on or off by the user. Switching on and off pull-up resistors is automatically performed by the parameterizable special module (PSM) depending on the selected operating mode of the input (e.g. parameter "wake-capable").
Analog
Wiring of multifunction inputs 01 and 10
Wiring of multifunction inputs 08 and 09
Input voltage range
The analog inputs are low-active.
Multifunction inputs 08 and 09 have an input voltage range of 0 to 20 V.
Multifunction inputs 01 and 10 have an input voltage range of 0 to 40 V.
Input current for multifunction inputs 01 and 10
Multifunction inputs 01 and 10 have a standardized analog input current of 110 uA (with 13.5 V) without active pull-ups.
With active pull-up resistor and closed switch, a standardized switch current of 10 mA flows.
Input current for multifunction inputs 08 and 09
Multifunction inputs 08 and 09 have a standardized analog input current of 100 μA (with 13.5 V) without active pull-ups.
With active pull-up resistor and closed switch, a standardized switch current of 120 μA flows.
With active "strong pull-up resistor" and closed switch, a standardized switch current of 5.7 mA flows.

Wiring of multifunction inputs 02, 03 and 04
Switchable pull-up resistors
The "strong pull-up resistors" (2.1 kΩ) of multifunction inputs 08 and 09 can be switched on or off individually by means of the controller.
The pull-up resistors (100 kΩ (± 7 %)) of multifunction inputs 08 and 09 can be switched on or off individually by means of the controller.
The separate pull-up resistors (1.2 kΩ) of multifunction inputs 01 and 10 can be switched on or off individually by means of the controller.
Switching threshold
The inputs are measured analogously; the switching thresholds can be configured by means of diagnosis.
Wake capability
The wake capability can be parameterized for multifunction input 08; an edge change at the input wakes the control unit.
This function requires the low-impedance pull-up resistor to be activated.
Pull-down resistors
The pull-down resistors (2.1 kO) are directly connected to the ground connection.
Switching threshold
The following switching thresholds apply for multifunction inputs 02, 03 and 04:
- ON ≥ 6.3 V
- OFF ≤ 3.0 V
- Hysteresis ≥ 0.4 V
Wake capability
The wake capability can be parameterized individually; a flank change at the input wakes the control unit.
Permissible input voltage
The permissible input voltage for the high-active inputs is between 0 V and battery voltage.
Low-active
Wiring of multifunction inputs 05, 06 and 07
Switchable pull-up resistors
The pull-up resistors (2.1 kO) can be switched on or off individually by means of the controller.
Switching threshold
The following switching thresholds apply for multifunction inputs 05, 06 and 07:
- OFF ≥ 6.3 V
- ON ≤ 3.0 V
- Hysteresis ≥ 0.4 V
Wake capability
The wake capability can be parameterized individually; a flank change at the input wakes the control unit.
The pull-up resistor belonging to the input must be activated.
Permissible input voltage
The permissible input voltage for the low-active inputs is between 0 V and battery voltage.
