Pro I: Digital-I/O- and Counter Modules
Pro-CO4-I Rev. A
ADwin
5.8.18 Pro-CO4-I Rev. A
The basic functions of the module Pro-CO4-I Rev. A are similar to those of the
module Pro-CO4-T Rev. A (see page 125 ).
What is different is the fact that the counter inputs of the module Pro-CO4-I are
optically isolated from the system circuit. The event input, too, is optically iso-
lated from the system circuit.
The input voltage range of the counter and event inputs can be set by jumpers
to 0…5V, 0…12V or 0…24V. The default setting is 0…24V.
