Description
Product Name: 1790D-T4T0 Allen Braley Power module
Product details:
The Allen-Bradley 1790D-T4T0 is a compact, high-performance I/O module from the CompactBlock LDX I/O series. It is designed to provide a cost-effective distributed I/O solution for DeviceNet networks, particularly where space is at a premium.
Product Overview
The 1790D-T4T0 is a DeviceNet Base Block featuring a combination of digital inputs and outputs. It serves as an interface between the sensors/actuators on the factory floor and the DeviceNet scanner.
-
Inputs: 4 Sink Inputs (24V DC)
-
Outputs: 4 Source Outputs (24V DC)
-
Network: DeviceNet

Key Advantages
-
Space-Efficient: Its ultra-compact “LDX” (Low-cost Distributed eXpansion) design makes it ideal for mounting inside small terminal boxes or directly on machinery.
-
Cost-Effective: Offers a lower price point per I/O point compared to modular chassis-based systems.
-
Easy Integration: Features “Auto-Baud” rate detection, allowing it to automatically sync with the DeviceNet network speed without manual configuration.
-
Removable Terminals: Simplifies wiring and maintenance, as you can replace the module without disconnecting every individual wire.
Important Precautions
-
Power Supply: Ensure the DeviceNet power supply is Class 2 rated to prevent damage to the electronics.
-
ESD Protection: This equipment is sensitive to electrostatic discharge. Always wear a grounding wrist strap when handling the unit.
-
Environment: The 1790D-T4T0 has an IP20 rating. It must be installed in an enclosure that protects it from moisture, dust, and corrosive vapors.
-
Output Current: Do not exceed the rated output current per channel (typically 0.5A). Overloading can cause the module to fail or trip its internal protection.
Product Applications
The 1790D-T4T0 is widely used in distributed control architectures where “islands” of I/O are needed far from the main controller.
-
Conveyor Systems: Managing photo-eyes (inputs) and small motors or diverters (outputs).
-
Packaging Machinery: Controlling solenoids and proximity sensors in tight mechanical spaces.
-
Material Handling: Real-time monitoring of limit switches on automated storage systems.
-
Assembly Lines: Providing local I/O for robotic workstations.
