Product Summary
The 1734-IM4 from Allen-Bradley provides a compact 4-channel digital AC input solution. This module reliably monitors 220V AC signals within a POINT I/O system. Its design supports straightforward DIN rail mounting and simple wiring. Engineers benefit from its robust electrical isolation and programmable filter settings.
Theme Option A: Product Procurement & Buyer Guide
Understanding the 1734-IM4 Core Specifications
This module operates with an input voltage of 220 Volts AC. The on-state voltage range spans from 159 to 264 Volts AC. Procurement teams must verify this range matches their line voltage. The module draws a maximum POINTBus current of 75 milliamps. This low power consumption reduces strain on the system power supply. The 1734-IM4 uses a keyswitch position of 8 for its mounting base.
Solving Industrial Pain Points for Engineers
The 1734-IM4 solves the need for reliable high-voltage AC sensing. It offers four non-isolated sink inputs within a single group. This configuration simplifies wiring for common AC applications. The module’s status indicators show network, module, and input status. This feature speeds up system commissioning and troubleshooting. Engineers gain clear visual feedback without extra diagnostic tools.
Critical Electrical and Mechanical Selection Data
The module requires 22 to 14 AWG solid or stranded copper wire. Its compact dimensions are 2.21 x 0.47 x 2.97 inches. The unit weighs only 30.9 grams, which eases panel layout. The nominal input impedance sits at 22.3 kiloohms. This high impedance minimizes loading on the input signal source. The continuous isolation voltage reaches 240 Volts from field to system.
Filter Performance and Timing for Your Application
The 1734-IM4 includes a fixed 20-millisecond hardware filter. You can program an additional digital filter from 1 to 65.535 milliseconds. This range allows precise noise rejection for AC signals. Both ON to OFF and OFF to ON delays include this same filter time. This symmetrical timing simplifies your control logic design.
Power Dissipation and Thermal Management
Maximum power dissipation is 0.80 Watts at 264 Volts AC. The maximum thermal dissipation is 2.73 BTU per hour at 264 Volts AC. This low heat output allows dense module placement in cabinets. You do not need special cooling for a standard POINT I/O rack. The module’s efficiency contributes to overall system reliability.
