Description

The Allen-Bradley 1769-OW8 module is an output module designed for both AC and DC power sources. The module is produced by Allen-Bradley/Rockwell Automation and it is built for industrial usage. This compact AC/DC relay contact module is part of the Bulletin 1769 product line and it has 8 output points which are normally open. The available outputs are separated into 2 groups of 4.

The 1769-OW8 module is a relay contact module from the Allen-Bradley CompactLogix series. It is equipped with 8 output channels and it can use AC and DC voltage.

The 1769-OW8 relay contact module operates with a terminal block that is replaceable. It also supports a door label that can be used to list the specifications of the module and its components.

The 1769-OW8 module has an operating voltage of 5 to 265 Volts AC or 5 to 125 Volts DC and a current draw of 125 milliamps at 5.1 Volts and 100 milliamps at 24 Volts. Additionally, the module dissipates a maximum of 2.83 Watts of heat and it has an on-state current of 10 milliamps at 5 Volts DC (minimum). The off-state leakage is a maximum of 0 milliamps. The maximum current per point is 2.5 Amps while the maximum current per module is 16 Amps. The isolation voltage of the 1769-OW8 module is verified at 1836 Volts for 1 second and at 2596 Volts DC for 1 second in dielectric tests. The tests refer to the output point to bus isolation voltage and group to group isolation voltage.

The 1769-OW8 relay contact module is compatible with Allen-Bradley controllers from the CompactLogix series that it is a part of, and it is compatible with Allen-Bradley MicroLogix controllers.

The 1769-OW8 module uses power supply components with the following catalog numbers: 1769-PA2, 1769-PB2, 1769-PA4, and 1769-PB4. It needs just 1 slot and it has a power supply distance rating of 8 modules. The module can be installed on a DIN rail or it can be mounted directly on a panel.
