The 1756-OB32 is an Allen-Bradley High-Density 24VDC discrete output module. This module is used to drive output devices connected to each channel of this module. Output devices may include pilot lamps, relays, contactors, panel annunciators, solenoids, buzzer, siren, horn and other actuating devices.
This output module is ideal for use in systems where a high number of outputs are existing with limited space for installation of larger or expansion ControlLogix chassis. It occupies single slot and supports installation in local or remote chassis. This module is compatible for use with any ControlLogix processor including the more recent ControlLogix versions.
This 1756-OB32 is provided with 32 LED indicators that is used to monitor channel actuations. This front panel indicators are important visual troubleshooting tool as it may be used to confirm the controller’s command to the connected load. Each channel has individual configurable parameters and support output forcing. This module only supports sourcing configuration.
A Removable Terminal Block (RTB) is required for use with this module. Appropriate RTB for this output module are 1756-TBCH and 1756-TBS6H. RTBs are used to provide modular connection to output devices. During module replacement, the entire RTB is removed from the installation slot and transferred to the replacement module. This prevents wiring reworks for faster maintenance and troubleshooting.
