1746-OW4

The Allen-Bradley 1746-OW4 is a relay contact output module. It has 4 relay contact outputs and no relay contact inputs. It has 4 common points. It is an AC/DC relay output module that is suitable for any application of relay contact type outputs. The relay contact module is vulnerable to chemical exposure because it may degrade the sealing materials. Therefore, the 1746-OW4 is recommended to inspect the module periodically to avoid any degradation and to quickly replace the module if there is any degradation. The 1746-OW4 module has 2 ranges of operating voltages: 5-125V DC and 5-265V DC. The signal delay for both the ON and the OFF state is 10 ms. The backplane current consumption of this module at both 5V DC and 24V DC is 0.045A for each. The minimum load current of this module is 1 mA at 5V DC. Please refer to the user manual to learn more about the continuous current per point in this module. The maximum thermal dissipation of the 1746-OW4 module is only 1.9 W. The heat dissipation per point for the 1746-OW4 is 0.133 W. This module also has a maximum continuous current per module of 8A. Please disconnect the power to the module before you do any wiring or installation. Always refer to the user manual during the installation process, to prevent accidents.
