Allen-Bradley 1734-485ASC | Point I/O Serial Interface Module

Product Overview

The AB 1734-485ASC is a serial interface module in the Allen-Bradley Point I/O 1734 series. It facilitates seamless communication between ASCII devices and DeviceNet networks. This compact module connects to RS-485 or RS-422 networks, ensuring reliable data transfer for industrial automation applications.

Engineered for robust operation, the 1734-485ASC uses a shielded cable to minimize electrical interference. Only one end of the shield should be grounded to prevent potential faults, while the module is mounted on a DIN rail for secure installation.

The 1734-485ASC supports 10–28.8 V DC voltage range and operates nominally at 24 V DC with low current consumption of 15 mA. Its compact 0.13 lb (0.06 kg) form factor ensures flexible installation in tight industrial control panels.
