Product Summary: Flexible 8-Point DC Control
The 1734-8CFG is a versatile POINT I/O module from Allen-Bradley. It features eight I/O points that automatically configure as inputs or outputs. This design simplifies inventory and provides flexibility for 11 to 28.8 Volt DC applications.
Theme A: Product Procurement & Buyer Guide
Simplify Your Panel Design with Auto-Configuring I/O
This module eliminates the need for separate input and output cards. The 1734-8CFG intelligently adapts its eight channels to match your wiring. You can reduce spare parts stock with just one module for both sensor reading and actuator control.
Technical Synergy for Application Success
The module operates with a minimum input voltage of 11 Volts DC. Its input current range spans from 2 to 5 milliamps in the on-state. This ensures reliable signal detection for standard 24V DC sensors and switches in your cabinet.

Industrial Durability in a Compact Footprint
Engineers designed this unit for DIN rail mounting in open enclosures. Its operational temperature range of -20 to 55 Celsius suits harsh factory environments. The low power dissipation of 2.6 Watts minimizes heat buildup in dense I/O racks.
Risk Mitigation for Critical Systems
This module provides reverse polarity protection for secure installation. You must power all connected I/O from a PELV or SELV compliant source. This requirement ensures safety and compliance with industrial isolation standards.
Seamless Integration with Your Control Network
The 1734-8CFG communicates via the POINTBus backplane. It supports auto-address and auto-baud features for easy setup. You can remove and insert the module under power without disrupting the network.

Theme B: Step-by-Step User & Installation Guide
Mechanical Mounting and Base Keying
First, install the appropriate 1734-TB, 1734-TBS, 1734-TOP, or 1734-TOPS terminal base. You must accurately key the mounting base to position value 1 before proceeding. Then snap the 1734-8CFG module onto the base securely.
Flexible Module Installation Timing
You can install this digital module before or after mounting the terminal base assembly. This flexibility simplifies panel wiring and retrofit tasks. The module fits securely onto the DIN rail without additional tools.
Wiring and Electrical Configuration
Each of the eight I/O points has an on-state output voltage range of 10 to 28.8 Volts DC. You must configure input filter times independently in millisecond intervals. The default filter setting is 1000 milliseconds for general-purpose noise rejection.

Power and Bus Current Specifications
The module draws a standard POINTBus current of 100 mA at 5 Volts DC. Ensure your backplane power supply can support this load. Thermal dissipation measures only 8.9 BTU per hour at maximum voltage output.
Compliance and Safety Checks
Verify all field wiring connects to a PELV or SELV rated power source. The open-style enclosure requires installation within a rated industrial control panel. Double-check the key switch alignment before applying system power.
