Allen-Bradley 1734-8CFG POINT I/O 8-Point Configurable DC I/O Module

The Allen-Bradley 1734-8CFG is a versatile 8-point configurable DC digital I/O module from Rockwell Automation's Bulletin 1734 POINT I/O series. Weighing approximately 0.10 kg (0.22 lbs), each of its 8 channels automatically self-configures to operate as either a digital input or digital output based on field wiring and controller programming, maximizing panel density and system flexibility.

Key System & Electrical Features

Designed for efficient power distribution, the 1734-8CFG operates on a 5V DC POINTBus backplane drawing 100 mA. Inputs accept a minimum on-state voltage of 11V DC with a 2 to 5 mA current range, while outputs deliver 10 to 28.8V DC. Built-in features include reverse polarity protection, programmable input filter times in millisecond increments (1000 ms default), and RIUP (Removal and Insertion Under Power) support for zero-downtime maintenance.

Installation & Operation Considerations

  • Keyswitch Setup: Set the terminal base mechanical keyswitch to Position 1 before snapping the 0.10 kg module into the base unit.
  • Power Source Compliance: Connect field I/O power exclusively from a Protected Extra Low Voltage (PELV) or Safety Extra Low Voltage (SELV) power supply.
  • Base Compatibility: Install only into compatible 1734 wiring bases (1734-TB, 1734-TBS, 1734-TOP, or 1734-TOPS) to guarantee proper contact alignment and backplane connectivity.

Frequently Asked Questions

Q1: What does 'self-configuring' mean for the Allen-Bradley 1734-8CFG?
A1: Each of the 8 channels automatically detects and configures itself to operate as an input or an output depending on connected field wiring and software setup.

Q2: What terminal base units work with the 1734-8CFG module?
A2: It is compatible with 1734-TB, 1734-TBS, 1734-TOP, and 1734-TOPS mounting bases utilizing mechanical keyswitch position 1.

Q3: What power supply requirement applies to connected field devices?
A3: All connected field inputs and outputs must be powered by a SELV (Safety Extra Low Voltage) or PELV (Protected Extra Low Voltage) rated power supply.
