Overview

2 Overview
The I/O module serves to control proportional valves so the valves can be set precisely in
proportion to the specified setpoint. This can be used, to control hydraulic axes and
presses, as well as proportional filling valves, for example. The I/O module has two cur-
rent-controlled output channels with switchable dithering that can be current-controlled
via pulse width modulation. One unidirectional or bidirectional coil and two unidirectional
coils can be connected to each output channel. Through parameters, the I/O module can
be adjusted to the valve characteristics. For example, the operating range or the valve's
characteristic curve can be individually set in this way.
In addition, the I/O module allows configuration of setpoint ramps to prevent discontinu-
ities in the current curve in the event of setpoint jumps. The characteristics of the rising or
falling ramps can be parameterized.
The I/O module also has two digital inputs that can be used to monitor threshold value
switches, for example.
The following basic operating modes are available:
• Operating mode with one valve
• Operating mode with two valves
Configuration and parameterization are performed via device description files, with
WAGO-I/O-CHECK or by means of function blocks.
The I/O module can be used with the head stations of the WAGO I/O System 750/753
listed in the
version.
