Application: Inputs Control inputs can be used either with the internal +5 V
DC
supply voltage, or
with external voltages (5...12 V
DC
), regardless of the polarity. For higher volt-
ages (48 V max.), appropriate series resistors must be used, see table below.
Please note that the control inputs are arranged in groups of four, each group
having one of the control connections in common. Total current supplied by
all +5 V
DC
pins of one card must not exceed 650 mA.
Input Voltage Series Resistor
24 V
DC
2.2 kΩ min.
36 V
DC
3.3 kΩ min.
48 V
DC
4.7 kΩ min.
Outputs Control outputs are open-collector outputs pulling to GND if active. For
activating e.g. relays or LEDs, either the internal +5 V
DC
supply voltage
or external voltages of up to 24 V
DC
may be used. Output current must not
exceed 50 mA per output. Please make sure to use appropriate series resistors
if necessary. Total current supplied by all +5 V
DC
pins of one card must not
exceed 650 mA.
