The 750-517/040-000 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 a direct connection to actuators.
The actuators can be wired directly to the CAGE CLAMP
®
connectors DO 1 or
/DO 1 (i.e. NOT DO 1) of channel 1 resp. DO 2 or /DO 2 (i.e. NOT DO 2) of
channel 2.

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”.

The I/O module incorporates 2 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 2 relays is
possible as well as a serial connection of several relays with block wise
connection of several modules.

The relay contacts 11 and 21 can be connected to an external voltage of
230 VAC resp. 300 VDC.

No use of different phases of a three-phase system on both channels!
The max. voltage between adjacent connections may not exceed 250 VAC. The
use of different phases of a three-phase system on both channels of the relay
output module 750-517/040-000 is not permitted!

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.
