Allen-Bradley 1734-IM2 POINT I/O Digital AC Input Module
Product Summary
The Allen-Bradley 1734-IM2 is a compact POINT I/O digital AC input module designed for reliable 220V AC sensing. This module features two non-isolated sink inputs and a key switch position of 8. Engineers trust this module for its robust input range from 159 to 264 Volts AC. Its small footprint saves valuable cabinet space without sacrificing performance.
Theme: Product Procurement & Buyer Guide
Procurement managers value the 1734-IM2 for its specific voltage handling capabilities. This module operates with an external AC supply of 220 Volts at 60 Hertz. It accepts a wide input voltage range between 159 and 264 Volts AC. This flexibility makes it suitable for global industrial applications with varying power quality.
The module draws a maximum POINTBus current of only 75 milliamps at 5 Volts DC. This low power consumption reduces strain on your system’s backplane power supply. Its nominal input impedance measures 22.3 kiloohms, ensuring minimal signal loading. These electrical characteristics help simplify system power budgeting.

Application engineers appreciate the module’s clear on-state electrical specifications. At a nominal 220 Volts AC, the module draws 8.5 mA of current. The on-state current ranges from 6.2 mA at 159 Volts to a maximum of 10.2 mA at 264 Volts. These precise values allow for accurate input circuit design and sensor selection.
The off-state performance is equally well-defined for reliable system operation. The module’s maximum off-state voltage is only 43 Volts AC. Its maximum off-state current is a low 2.9 mA. These thresholds prevent false triggering from electrical noise or leakage currents, ensuring signal integrity.
Physical dimensions are critical for panel layout and procurement planning. The module weighs approximately 30.9 grams or 1.09 ounces. Its compact size measures just 2.21 x 0.47 x 2.97 inches. This small form factor allows for high-density I/O installations in tight control cabinets.

Proper installation begins with selecting the correct terminal base unit. The 1734-IM2 is compatible with the 1734-TB, 1734-TBS, 1734-TOP, or 1734-TOPS bases. You must rotate the keyswitch on the mounting base to position 8 before installation. This mechanical keying prevents incorrect module insertion.
Mount the terminal base unit onto a standard DIN rail for secure placement. The module uses an open-type enclosure, so install it inside a suitable cabinet. Ensure the cabinet protects the module from dust and direct contact. Verify the ambient temperature stays between -20 and 55 degrees Celsius for operation.
Wiring requires 14 to 22 AWG solid or stranded copper wire rated at 75 degrees Celsius. Strip the wire insulation carefully to ensure a solid connection in the terminal block. Connect your AC input field devices to the appropriate input terminals. The module features two inputs configured as one group of two non-isolated sinks.
Apply power to the system and check the module’s status indicators for real-time feedback. The module provides continuous isolation of 240 Volts from the field-side to the system. This isolation protects your backplane and controller from potential voltage transients. Always verify wiring against the module’s documentation before energizing the system.
