The 750-506 (2DO 24V DC 0.5A/ diagnostics) Digital Output Module transmits
binary control signals from the automation device to the connected actuators
(e.g., solenoid valves, contactors, transmitters or other electrical loads).

These output modules can recognize a short circuit to ground, a line break and
an overload in either channel.

The I/O module has 2 output channels. 2 actuators with ground (earth) wire
may be directly connected to signal output DO 1, 0 V and ground
or signal output DO 2, 0 V and ground.

Limit all induced voltage!
The electronic components of the I/O module can be damaged by the induced
voltage produced when inductive loads are de-activated.
An appropriate protection circuit, e.g., a recovery diode, must be installed in
parallel to the load to limit this induced voltage.

The I/O module outputs provide high-side switching. If the signal status of an
output channel is at "high" the 24 V potential for field power will be switched to
the appropriate output connection.

The supply voltage for the field side is derived from an adjacent supply module
by means of power jumper contacts.

Provide for overload protection!
Overloading can damage the electronic components of the I/O module.
A fused supply module (750-601) must be installed upstream of the I/O module
to protect it against overloading!

The status of the two output channels is indicated via green status LEDs. A color
change to red signals an open circuit, overload or a short circuit.

The I/O module 750-506 (2DO 24V DC 0.5A/ diagnostics) receives the 24 V
voltage supply for the field level from an upstream I/O module or from the
fieldbus coupler/controller via blade-formed power jumper contacts. It then
