Product Details:
Manufacturer : ALLEN BRADLEY
Product No. : 1756-OB32
Product Type : DC Output Module

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.

Recommended fuse for this module is the 5x20mm 800 mA supplied by the Littelfuse p/n SP001.1003 or the Schurter p/n 216.800. A Removable Terminal Block (RTB) is required for wiring output connections. For this module, the only compatible RTB are the cage clamp 1756-TBCH and the spring clamp 1756-TBS6H. Remember to install and ground the chassis and power supply prior to installing the module with the RTB. The module also has status light indicators that show the module status and the individual I/O status.

The communication formats that work with the 1756-OB32 module are scheduled output data, output data, rack optimization, listen-only rack optimization, and listen-only output data. You can also configure the states in Fault Mode per point and the states in Program Mode per point. You can choose the following options for both: Hold Last State, On, or Off. Note that this is set by default for all.

The 1756-OB32 module has a voltage category of 12/24V DC source and an operating voltage range of 10 to 31.2V DC. Its current draw at 5.1V DC is 300 mA and at 24V, it has a current draw of 2 mA. It also has a total backplane power of 1.58W, a maximum off-state leakage current per point of 0.5 mA per point, and a maximum on-state voltage drop of 200 mV DC at 0.5 A. Its maximum surge current per point is 1 A for 10 ms per point that is repeatable every 2 s at 60 Degrees Celsius and its minimum load current is 3 mA per point. The maximum current per point at 50 Degrees Celsius is 0.5A and 0.35A at 60 Degrees Celsius, while the maximum current per module is 16 A at 50 Degrees Celsius and 10 A at 60 Degrees Celsius. This module also has a continuous isolation voltage of 250V.
