WAGO-I/O-SYSTEM 750 XTR
750-508/040-000 2DO 24 VDC 2A/ Diagn XTR
Device Description
3
The 750-508/040-000 (2DO 24 VDC 2A/ Diagn XTR) Digital Output Module
transmits binary control signals from the automation device to the connected
actuators (e.g., solenoid valves, contactors, transmitters, relays 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, providing a direct connection to actuators.
The actuators can be wired directly to the CAGE CLAMP
0 V or DO 2 and 0 V.
The assignment of the connections is described in the "Connectors" section.
Connection examples are shown in section "Connect Devices" > ... >
"Connection Example(s)".
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 output channels are electrically short-circuit-protected.
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.
One LED per channel indicates the signal status, an overload, a short circuit or a
wire break.
The meaning of the LEDs is described in the "Display Elements" section.
The I/O module 750-508/040-000 (2DO 24 VDC 2A/ Diagn XTR) 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
provides these potentials to subsequent I/O modules via spring-formed power
jumper contacts.
