Application Inputs
Control inputs can be used either with the in5 VDC supply voltage, or
with external voltages (5-12 VDC), 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 VDC pins of one card
must not
exceed 650 mA.
Input Voltage
Series Resistor
24 VDC
2.2 kΩ min.
36 VDC
3.3 kΩ min.
48 VDC
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 in5 VDC supply voltage
or external voltages of up to 24 VDC 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 VDC pins of one card
must not
exceed 650 mA.
