Product Overview

The Allen-Bradley 1734-OB8 is a POINT I/O eight-channel digital output module manufactured by Rockwell Automation. It provides eight non-isolated, DC sourcing digital outputs for supported industrial automation and distributed I/O systems. The module is rated for a nominal 24V DC output with an on-state operating voltage range of 10–28.8V DC. Each output channel supports a maximum current of 1.0A, subject to a combined module output current limit of 3.0A. The individual channel ratings must not be added together to imply an 8A module capacity. The 1734-OB8 provides a manufacturer-specified maximum switching delay of 0.1ms for both OFF-to-ON and ON-to-OFF transitions. Its surge output capability is 2A for 10ms, repeatable every three seconds, subject to the manufacturer's specified operating limits. The module draws up to 75mA at 5V DC from the POINTBus and uses a nominal 24V DC field supply. Field power is distributed through the compatible POINT I/O wiring system, which must be selected and connected according to Rockwell Automation installation instructions. This module is an ordinary DC sourcing digital output module, not a POINT Guard safety output module and not the electronically protected 1734-OB8E variant. The output channels are not individually isolated. Rockwell Automation currently lists the catalog number 1734-OB8 as Active. The supplied actual product photographs show matching carton and module labels identifying 1734-OB8, Series C, serial marking 315031, date 2023/08/31 and Singapore as the country of origin. The physical module nameplate also shows firmware marking 3.022. The model and serial number markings match between the carton and the module. Functional testing, independent manufacturer authentication and terminal base inclusion have not been verified. Please confirm the exact supplied module, output load requirements and installation accessories before ordering.
