The Allen-Bradley 1734-IB4D is a high-performance digital input module from the trusted POINT I/O series. Specifically, this module provides four sinking inputs, each rated at 24 Volts DC nominal. Furthermore, every input channel includes a dedicated status indicator light, so users can quickly verify the operational state of each point. This 1734-IB4D module also integrates advanced diagnostic features. Consequently, it helps identify field-side faults, such as open wires or short circuits, which significantly reduces troubleshooting time.
This input module operates with a nominal input voltage of 24V DC, while its acceptable range spans from 10 to 28.8V DC. The maximum input current per channel is only 5 milliamps, making it energy-efficient. Additionally, the 1734-IB4D draws a POINTBus current of 50 milliamps at 5V DC. Its maximum power dissipation is rated at 1.9 BTU/hour under normal conditions, and it reaches 3.4 BTU/hour at 28.8V DC. Therefore, this module suits applications requiring low thermal output. The terminal base screw torque is specified at 0.8 N-m or 7 pounds per inch, ensuring secure and reliable wiring connections.
Regarding its physical dimensions, the 1734-IB4D measures just 2.2 x 0.47 x 2.97 inches, which enables space-saving installation in control cabinets. Moreover, it weighs only 1.14 ounces, so it adds minimal weight to your I/O assembly. In terms of environmental resilience, this module operates flawlessly across a wide temperature range, from -20°C to 55°C (-4°F to 131°F). Additionally, its open-style enclosure allows for flexible mounting, as you can install it either horizontally or vertically. Meanwhile, the module utilizes a Removable Terminal Block (RTB) mounted on the base for simple wiring and maintenance. For network integration, it supports various open networks, including EtherNet/IP, ControlNet, and DeviceNet.
First, ensure that the power supply is turned off before installing the 1734-IB4D module onto the DIN rail. Next, mount the base unit securely and then snap the module into place. After that, connect the field wiring to the RTB, ensuring proper polarity for the sinking inputs. Finally, restore power and verify the status indicators are functioning correctly. Regular inspection of the diagnostic LEDs can help prevent unexpected downtime. The compact footprint of this Allen-Bradley 1734-IB4D also makes it suitable for space-constrained panels.

1. What type of inputs does the 1734-IB4D support?
This module supports digital DC sinking inputs only. It accepts signals from devices such as proximity sensors, limit switches, and push buttons that provide a DC sinking output.
2. Can the 1734-IB4D be used with EtherNet/IP networks?
Yes, the 1734-IB4D is fully compatible with EtherNet/IP, as well as ControlNet and DeviceNet. It integrates easily into most Rockwell Automation architectures.
3. How can I tell if the 1734-IB4D is working properly?
Each of the four input channels has a status indicator LED. A lit LED means the input signal is active, while diagnostic LEDs help you detect wiring faults or short circuits.
4. What is the difference between sinking and sourcing inputs?
The 1734-IB4D is a sinking input module. This means it provides a path to ground (DC common) for the input signal. Sourcing inputs, on the other hand, supply voltage to the field device.
5. Is the 1734-IB4D suitable for high-temperature environments?
Absolutely. This module operates reliably in ambient temperatures ranging from -20°C to 55°C, making it ideal for harsh industrial settings.
