The 753-514 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).

The I/O module has 2 output channels, providing for direct connection of
actuators to the CAGE CLAMP
®
connectors DO 1 or /DO 1 of channel 1 and an
external N potential or DO 2 or /DO 2 of channel 2 and an external N potential.

Inductive loads must be dampened!
For the protection of relay coils and contacts, inductive loads must be dampened
with an effective protection circuit!
Examples of protection circuits can be seen in the section “Protective Circuits for
Contacts of Relay Modules”.

Loss of properties due to high switching power!
To prevent the gold layer from being damaged, 30 VDC switching voltages and
50 mA currents must not be exceeded. Higher switching power with switching arc
eventually evaporates the gold layer. This can cause the relay to lose its properties
in regards to minimum switching current.

The I/O module incorporates two change-over relays connected potential free.
This means on the field side only the connections of the relay contacts are present.
Therefore, both relays can be operated with different voltages.
Because of the potential free contacts also a serial connection of the two relays is
possible as well as a serial connection of several relays with block wise
connection of several modules.

Depending on the relay status the voltage of the middle contact 11 resp. 21 is
switched to the lower contact 12 resp. 22 or to the upper contact 14 resp. 24. In
the OFF state the contacts 11 resp. 21 are switched to the lower contacts 12 resp.
22.
