Product Procurement & Buyer Guide
Your Direct Replacement for AC Input Monitoring
The 1734-IM2 acts as a direct and efficient solution. It monitors AC voltage presence from field devices like sensors. This model simplifies your bill of materials with its two-input design. It replaces larger modules in space-constrained cabinets. This specific module requires a keyswitch position of 8 on its base.
Optimized for High-Voltage AC Environments
This module operates with a nominal input voltage of 220 Volts AC. It accepts a wide input range from 159 to 264 Volts AC. This tolerance ensures stable operation despite line fluctuations. The on-state current ranges from 6.2 mA to 10.2 mA. You can trust it for consistent signal detection in your machinery.
Guaranteed Electrical Isolation for System Safety
The 1734-IM2 provides continuous isolation voltage of 240 Volts. This isolates the field wiring from your system backplane. This feature protects your controller from electrical noise and surges. It enhances the overall safety of your automation network. Your system gains superior protection against ground loops.
Mechanical Fit and Environmental Resilience
The module measures just 2.21 x 0.47 x 2.97 inches. Its lightweight design makes installation easy on a DIN rail. You must use it with a compatible terminal base like the 1734-TB. It operates reliably in temperatures from -20 to 55 degrees Celsius. It handles high humidity from 5 to 95 percent non-condensing.
Procurement Checklist and Compatibility
You must purchase the correct mounting base separately. This module works with 14 to 22 AWG copper wire only. Verify your wire is rated for 75 degrees Celsius. The module draws 75 mA from the POINTBus at 5 Volts DC. Check your system power budget to ensure compatibility.
Expert Technical Evaluation & Performance Review
Accurate Signal Detection with Wide Voltage Tolerance
The 1734-IM2 ensures accurate on-state detection from 159 to 264 VAC. Its off-state threshold is a maximum of 43 Volts AC. This wide hysteresis prevents false triggering from electrical noise. This design guarantees reliable input state recognition for your logic. Your process will not suffer from intermittent signals.
Robust Current Handling for Industrial Loads
This module draws a nominal current of 8.5 mA at 220 VAC. Its maximum input current reaches 10.2 mA at 264 VAC. This consistent current draw allows for predictable power supply design. The module’s nominal input impedance is 22.3 kiloohms. This high impedance minimizes the load on your signal source.
Low Power Dissipation for Thermal Management
The 1734-IM2 dissipates a maximum of 0.48 Watts of power. This very low heat output is rare for an AC input module. It contributes to a maximum thermal dissipation of only 1.63 BTU/hour. Your control cabinet will not overheat from this module. You can place it in dense I/O banks easily.
Superior Mechanical Shock and Vibration Resistance
The module withstands operating vibration of 5 g at 10 to 500 Hertz. It also handles operating shock of 30 g. This ruggedness makes it perfect for heavy machinery environments. Non-operating shock tolerance is even higher at 50 g. Your investment remains safe during transport and operation.
Comprehensive Review of Environmental Tolerances
You can deploy this module in non-condensing humidity from 5 to 95 percent. Its non-operating temperature range is extremely wide from -40 to 85 Celsius. This allows for storage in unheated warehouses or hot attics. The module’s performance is consistent across its operating range. It provides a long service life in harsh conditions.
