Analog Output Function
The 1769-OF4 converts digital commands from the controller into analog electrical signals. Voltage outputs serve devices that require voltage references, while current outputs support compatible current-loop control inputs. Therefore, the selected output range must match the receiving device’s electrical requirements.
Output Channels and Protection
The module provides four single-ended analog output channels. Each channel must be configured and wired according to the intended signal type and the connected equipment. The module also lists open-circuit protection and short-circuit current support. Check the applicable technical documentation for the specific protection behavior and operating limits before commissioning.
Power and Mounting Requirements
The module draws 120 mA from the 5.1 V supply and 170 mA from the 24 V supply. Its maximum heat dissipation is 2.86 W, which should be considered when checking system power capacity and enclosure thermal conditions. The module supports DIN rail or panel mounting and occupies one slot in the applicable installation.
