1792D-0B4D | Allen-Bradley 4-Channel Sourcing Output Block - Petro Auto Tech

Product Overview

The 1792D-0B4D is a 4-channel sourcing output block from Allen-Bradley, part of the 1792D ArmorBlock MaXum I/O series. This compact module delivers reliable output control in demanding industrial environments. With an IP67 housing rating, it resists dust and water ingress, making it ideal for harsh factory floor conditions. The unit operates on a DeviceNet protocol and accepts a standard 24 V DC power supply.

Technical Specifications Analysis

The 1792D-0B4D provides four sourcing outputs, each capable of delivering up to 2A of current. The module total current is 4 A max load, ensuring balanced power distribution. Output leakage is minimal at ≤ 1.5 mA, enhancing efficiency. Surge current handling reaches 4 A for 10 ms, protecting against transient spikes. Built-in local logic enables intelligent response without a separate controller. Addressing is simplified via a rotary node selector, and M12 connectors handle both I/O and network connections. The unit weighs 0.88 lbs (0.40 kg) and has a UPC of 612598187010.

Application Scenarios & Usage Methods

This output block suits automated assembly lines where reliable on/off control of actuators, valves, or indicator lights is required. For example, in a packaging machine, each channel can drive a solenoid valve for pneumatic cylinders. The DeviceNet protocol allows seamless integration with PLCs like ControlLogix or CompactLogix. Use the rotary node selector to assign a unique network address, then connect M12 cables to both power and I/O devices. The IP67 rating permits installation in washdown zones or dusty environments without additional enclosures.

Installation Guide & Packing List

Mount the module securely using its integral mounting holes. Connect the DeviceNet trunk line via the M12 network connector. Attach field devices to the M12 I/O connectors, ensuring correct pinout for sourcing outputs. Set the node address using the rotary switch before powering up. Apply 24 V DC to the power-supply pins. The package includes the 1792D-0B4D module only. No cables, connectors, or mounting hardware are supplied. Refer to the Allen-Bradley installation manual for detailed wiring diagrams.

Purchasing Advice

When selecting an output block, verify that your system uses DeviceNet and requires sourcing outputs. The 1792D-0B4D is a cost-effective choice for four-channel control with built-in logic. Ensure your load current per channel does not exceed 2A and total load stays under 4A. For reliable supply and genuine Allen-Bradley products, choose Petro Auto Tech as your trusted partner.

Repair & Maintenance Tips

Periodically inspect M12 connectors for corrosion or damage. Clean the housing with a dry cloth; avoid solvents that may degrade the IP67 seal. Verify that the DeviceNet network terminator resistors are properly installed. Check output current levels with a clamp meter to ensure they remain within the 2A per channel limit. Store spare modules in a clean, dry environment at room temperature. Replace the unit if the housing is cracked or the connector pins are bent.
