Allen-Bradley 1734-OE4CK Point IO Analog Output Module

Allen-Bradley 1734-OE4CK POINT I/O 4-Point Analog Output Module is a four-channel analog current-output card for the POINT I/O distributed I/O system, designed to mount to a POINT I/O backplane and operate with a compatible terminal base such as the 1734-TB or 1734-TBS. The CK suffix indicates conformal coating for use in harsher environments, expanding reliability in conditions with moisture or contaminants. Each of the four outputs provides a DC analog current signal sourced from the field power supply, which for this module accepts a range of 10 to 28.8 V DC; the field power current requirement is about 110 mA at 24 V DC to support the outputs. There is no isolation specified between individual outputs or between outputs and field power, meaning all channels share the same field-side supply. This module is commonly used to drive analog actuators, valves, or similar devices in industrial automation, with installation guidance found in the 1734-IN034 installation instructions and the POINT I/O Modules Selection Guide.
