Product Summary
The 1734-IA2 is a compact digital AC input module from Rockwell Automation. It offers two 120V AC input channels for reliable signal monitoring. Engineers use this module to integrate discrete sensors into ControlNet, DeviceNet, or EtherNet/IP networks.
Product Procurement & Buyer Guide
Why Choose the 1734-IA2 for Your System
Procurement managers value the 1734-IA2 for its proven compatibility with Allen‑Bradley Point I/O platforms. This module accepts input voltages from 85 to 132V AC at 47‑63 Hz. It delivers a nominal input impedance of 10.6 kΩ and draws only 75 mA at 5V DC from the POINTBus.
Key Technical Specifications for Sourcing
The module dissipates just 0.35 W at 132V AC. Its thermal dissipation is 1.19 BTU/hour at the same voltage. Isolation rating reaches 240V AC continuous, tested to 3250V DC for 60 seconds. These figures ensure robust electrical safety in industrial cabinets.
Compatibility and Network Support
The 1734-IA2 works seamlessly with ControlNet, DeviceNet, and EtherNet/IP adapters. It requires only one group of two inputs. Each input channel has a status indicator for quick diagnostics. The module weighs just 30.9 g and measures 56 x 12 x 75.5 mm.
Application Scenarios for Procurement
Buyers often select this module for monitoring pilot lights, limit switches, and pushbuttons. Its compact profile allows dense I/O layouts. The open‑style enclosure simplifies wiring access. Engineers appreciate the 8 key switch positions for network address configuration.
Step‑by‑Step User & Installation Guide
Mechanical Mounting Instructions
Mount the 1734-IA2 either horizontally or vertically on a DIN rail. Secure it using the module’s built‑in locking mechanism. Ensure adequate clearance for heat dissipation. The open‑style enclosure requires no additional ventilation.
Wiring the AC Inputs
Connect the AC supply to the “Input 0” and “Input 1” terminals. Use wire sizes from 0.2 to 1.5 mm². Tighten each screw terminal to 0.5 N·m. Verify input voltage remains between 85 and 132V AC at 60 Hz nominal.
Network Integration Steps
Attach the module to a compatible Point I/O bus adapter. Set the key switch to your network type. The POINTBus current consumption of 75 mA at 5V DC is automatically supplied. No external power is needed for the bus.
Status Indicator and Testing
Each input features a green LED that illuminates when the channel is on. After wiring, apply power and toggle each input. Confirm the corresponding indicator lights. The module responds within one AC cycle.
Horizontal vs Vertical Installation
The compact dimensions allow installation in either orientation. Ensure the DIN rail is level. The module’s clip‑on design holds it firmly. For vertical mounting, allow 12 mm width per module.
