About 1794sc-IF8IU

The 1794SC-IF8IU is an input module manufactured by Allen-Bradley. The Allen-Bradley 1794SC-IF8IU Input Module belongs to Series E of the 1794 FLEX I/O input modules. The Allen-Bradley 1794SC-IF8IU Input Module features 5.18 W thermal dissipation, 31 mA input overcurrent protection, 0 to 5 Volts DC input voltage, 0 to 20 mA input current, 8 channels, 28 input types, and high/low alarms for each channel. The Allen-Bradley 1794SC-IF8IU Input Module features an open type enclosure rating. The Allen-Bradley 1794SC-IF8IU Input Module is mounted to the chassis grounded by the DIN rail. The users should utilize yellow chromated steel and a zinc plated DIN rail to enhance correct grounding. The usage of other DIN rail material such as plastic and aluminum that brings about oxidation, corrosion, or poor conduction can cause intermittent platform grounding of the Allen-Bradley 1794SC-IF8IU Input Module. The Allen-Bradley 1794SC-IF8IU Input Module features 8 channels which are fully isolated and have an analog capability to suit noisy environments.

When inserting or removing the Allen-Bradley 1794SC-IF8IU Input Module, the users are recommended to remove the field-side power. The Allen-Bradley 1794SC-IF8IU Input Module is modified to make it easy for inserting and removing the FLEX I/O input module under the backplane power. An electrical arc can exist when the users insert or remove the Allen-Bradley 1794SC-IF8IU Input Module while the field-side power is supplied to the FLEX I/O input module. The occurrence of repeated electrical arcing may result in excessive wear to contacts on both the Allen-Bradley 1794SC-IF8IU Input Module and the mating connector. The Allen-Bradley 1794SC-IF8IU Input Module transfers data from the analog I/O module (block transfer read) to the analog I/O module (block transfer write) by utilizing the BTR and BTW instructions in the users’ ladder diagram programs. The guidelines allow the Allen-Bradley 1794SC-IF8IU Input Module to access the status and input values from the I/O module and enable the users to send output values to obtain the FLEX I/O input module’s mode of operation. At the front panel of the Allen-Bradley 1794SC-IF8IU Input Module are diagnostic indicators that show both the fault status and the normal operation in the users remote I/O system.
