1791D-0V16PX

The 1791D-0V16PX is an Allen-Bradley part that belongs to the 1791D CompactBlock I/O series. It is a 16-sinking output expansion module that has a built-in DeviceNet adapter and power supply. Its enclosure type is IEC IP20 and it has an output on-state voltage range of 10 to 30 Volts DC while its output on-state current is 0.5A max. The 1791D-0V16PX module is appropriate for operations that involve an immense distribution of I/O blocks close to sensors and actuators. This module also works properly with applications in a limited operating space. The 1791D CompactBlock I/O products, including the 1791D-0V16PX, are compact-sized. This feature allows these products to fit into confined areas and shallow enclosures. Compared to the 1790 CompactBlock LDX I/O blocks, the 1791D parts have higher environmental specifications. They help expand the application range and lower wiring costs. Due to the simple control functions of these blocks, the sense-to-actuation time is faster. These products also come with selectable input filters that allow users to choose on-to-off or off-to-on delays. The output short-circuit protection is also a beneficial feature of this series as it keeps outputs away from accidental miswiring.

The 1791D-0V16PX is an expansion block that works well with all base blocks. It is run by an external 24 Volt DC source that is network independent. This expansion block also comes with a 4-centimeter ribbon cable to attach it to the base block. It also has a removable screw-clamp terminal strip that allows for an easier I/O block replacement without rewiring. The 1791D-0V16PX can be mounted either on a panel or to a DIN rail in any orientation.
