Product Summary
The Allen-Bradley 1734-IM4 delivers four non-isolated digital AC input channels for your distributed control system. This module reliably detects signals from 159 to 264 Volts AC. Engineers value its programmable digital filter for eliminating noise on industrial power lines.
Theme A: Product Procurement & Technical Selection
Core Voltage Specifications
The 1734-IM4 module operates with a nominal input voltage of 220 Volts AC. Its acceptable on-state voltage ranges from 159 to 264 Volts AC at 60 Hertz. This wide range ensures stable detection across fluctuating power grids.
Channel Configuration Details
This module provides four input channels labeled from 0 to 3. These channels form one non-isolated group of sink inputs. The configuration simplifies wiring for standard AC sensing tasks in your control panel.
Programmable Filter Timing
The module includes a 20-millisecond hardware filter plus a digital filter. You can set the digital filter from 1 to 65.535 milliseconds in 1-millisecond increments. This flexibility helps you reject contact bounce and electrical noise.
Current and Power Data
Each channel draws between 6.2 mA and 10.2 mA depending on voltage. The module consumes a maximum POINTBus current of 75 mA at 5 Volts DC. Its total power dissipation reaches only 0.80 Watts at 264 Volts AC.
Theme B: Installation and Wiring Guide
Mechanical Mounting Steps
Mount the module on a DIN rail within an open-style enclosure. Use a mounting base with its keyswitch set to position 8. The module measures just 2.21 x 0.47 x 2.97 inches and weighs 30.9 grams.
Wire Selection and Termination
Use only copper wire with a gauge between 22 and 14 AWG. Both solid and stranded wire types work correctly with the terminal blocks. This wire range supports standard industrial field device connections.
Channel Status Monitoring
Each channel has a dedicated status indicator for quick visual feedback. The module also shows network status and overall module health. These LEDs help technicians diagnose problems without extra tools.
Electrical Isolation Parameters
The module provides continuous isolation of 240 Volts from the field-side to the system. This isolation protects the backplane and controller from voltage spikes. Always verify that your application does not exceed this rating.
