Allen-Bradley 1734-4IOL

The Allen-Bradley 1734-4IOL is a versatile POINT I/O module designed to meet the dynamic demands of industrial automation. Boasting four configurable channels, this module offers the flexibility to function as an IO-Link Master, facilitating seamless communication with IO-Link compatible devices.

Technical Description:

In standard digital I/O mode, it offers four channels for digital input or output, with support for IEC61131-2 type 1 input. The ability to individually configure each channel enhances adaptability, allowing users to tailor the modules operation to specific requirements.

Furthermore, channels that are not in use can be easily disabled, optimizing the modules performance and resource utilization. This inherent flexibility positions the 1734-4IOL as an ideal solution for diverse automation applications, providing a reliable and customizable platform to address a range of industrial communication and control needs.

The Allen-Bradley 1734-4IOL module features versatile communication rates, supporting IO-Link functionality with rates of 4.8 kB, 38.4 kB, and 230.4 kB. These communication rates play a crucial role in determining the speed and efficiency of data exchange between the module and IO-Link compatible devices.

The 1734-4IOL module is designed with a specified isolation voltage of 50V (continuous). This indicates that the module can withstand a continuous voltage difference of up to 50 volts between different parts of the system, providing electrical isolation to prevent undesirable interactions between components.

For IO-Link communication, the Allen-Bradley 1734-4IOL module specifies a maximum device cable length of 20 meters. The allowed distance between the module and IO-Link compliant devices that are linked to it via IO-Link cables is specified by this parameter.

Power and Thermal Dissipation:

The 1734-4IOL module has a maximum power dissipation of 1.5 watts when operating at 28.8 volts DC. This figure represents the amount of electrical power that the module consumes while in operation. Additionally, the module has a maximum thermal dissipation of 5.12 BTU/hr (British Thermal Units per hour) when operating at 28.8 volts DC.

Wiring Specifications:

The module is designed to adhere to specific wiring standards and requirements. The wiring category for signal ports is identified as Category 2. This categorization is a reference to the capability of the module to withstand certain levels of electrical transients or disturbances.

The module supports a range of wire sizes for connection to its signal ports, accommodating wires with a diameter between 0.25 mm² and 2.5 mm² (equivalent to 22-14 AWG). Both solid and stranded copper wires are compatible with the module. These wires should be rated at a minimum of 75 °C (167 °F) or higher to ensure safe and reliable operation within the specified temperature limits.
