Device Description
The 750-597 I/O module (8AO 0-10V/±10V DC) generates standardized values of
0 V ... +10
V or −10 V … +10 V for the field range.
The I/O module has 8 output channels for field signals.
The actuators are connected to push-in CAGE CLAMP
®
terminals AO1 and
ground or AO2
… AO8 and respective ground.
The ground connections are available for all 8 channels on a common 0V ground
potential.
The assignment of the connections is described in the
“Connectors” section.
Connection examples are shown in section
“Connect Devices” > … >
“Connection Example(s)”.
The I/O module outputs are short-circuit-proof. However, a short circuit in an
output causes interruption in the other outputs of the I/O module.
The Output signal is electrically isolated and will be transmitted with a resolution
of 12 bits.
The operational readiness and the trouble-free local bus communication of the
channels are indicated via a green function LED.
A red error LED displays the status of the field-side power supply voltage.
The meaning of the LEDs is described in the
“Display Elements” section.
Power to the internal electronics is supplied via both the internal data bus and the
field supply.
The I/O module 750-597 (8AO 0-10V/±10V DC) 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.
Do not exceed maximum values via power contacts!
The maximum current that can flow through the power jumper contacts is 10 A.
The power jumper contacts can be damaged and the permissible operating
temperature can be exceeded by higher current values.
When configuring the system, do not exceed the permissible maximum current
value. If there is a higher power requirement, you must use an additional supply
module to provide the field voltage.
With consideration of the power jumper contacts, the individual modules can be
arranged in any combination when configuring the fieldbus node.
An arrangement in groups within the group of potentials is not necessary.
The 750-597 module can be used with the fieldbus couplers and controllers of
the WAGO I/O SYSTEM 750 of the specified version or higher listed in the
“Compatibility list” table.
