1734-485ASC

Overview

The Allen-Bradley 1734-485ASC is a Serial Interface Module designed to facilitate communication between DeviceNet and various ASCII devices such as RS-232, RS-485, and RS-422.

Key Features

• Weight: 0.13 lbs (0.06 kg)
• Series: POINT I/O
• Module Type: Serial Interface Module
• Key Switch Position: 2

Electrical Specifications

• Voltage Range: 10-28.8 volts DC
• Supply Voltage: 24 volts DC nominal
• Supply Current: 15mA at 24 volts DC

Connectivity and Shielding

• The 1734-485ASC module connects to RS-485 or RS-422 networks.
• It is equipped with a shielded cable to minimize electrical interference.
• Only one side of the shield is grounded to prevent ground loops; grounding both ends can cause faults.
• The shield should not be connected to the general side of the logic circuit and is typically grounded directly to the chassis.
• For the 1734-485ASC, the shield connection is made at the DIN Rail rather than the terminal removable block.
• The metal panel DIN Rail is mounted at the user’s Input-Output Interface.
