Device Description
The I/O module 750-509 (2DO 230V AC 0.3A/SSR) uses voltages up to 230 V
AC/DC for connected actuators or universal supply voltage loads.
The I/O module has 2 output channels, providing a direct connection to 2
actuators with functional ground connection.
The actuators are connected to the following CAGE CLAMP
®
connectors
directly: signal output DO 1 and N or signal output DO 2 and N.
The assignment of the connections is described in the “Connectors” section.
Connection examples are shown in section “Connecting Devices” > … >
“Connection Example(s)”.
As a switching relay, there are two high-performance MOSFETs in the I/O
module. The actuators can be mechanically controlled continuously and free of
wear from the I/O module's semiconductor outputs. The MOSFETs are non-
isolated, i.e., the potential for the field supply touches one of the relay contacts
(0 V … 230 V AC/DC).
When a relay is closed, the field potential applied is then routed to the associated
second relay contact DO 1 or DO 2.
Control of the semiconductor outputs is fully isolated.
The switching status of the two relays is indicated via green status LEDs.
The meaning of the LEDs is described in the “Display Elements” section.
The I/O module receives the 0 V ... 230 V AC/DC power supply, the N potential
and the ground potential for the field level from an upstream I/O module and
makes the potentials available to subsequent I/O modules via the power jumper
contacts designed as spring contacts.
Do not exceed maximum current via power jumper contacts!
The maximum current to flow through the power jumper contacts is 10 A.
Greater currents can damage the contacts.
When configuring your system, ensure that this current is not exceeded. If
exceeded, insert an additional supply module.
The I/O module 750-509 can be used with all fieldbus couplers/controllers of the
WAGO-I/O-SYSTEM 750.
