Mengenai Produk

Allen-Bradley 1790D-T0W6 6-Point Relay Output Base Module

Core Product Information

  • Brand: Allen-Bradley
  • Model: 1790D-T0W6
  • Output Configuration: Six (6) Form A (Normally Open) single-pole, single-throw relay outputs.
  • Relay Type: Electromechanical relay, providing physically isolated contacts.
  • Contact Life: 300,000 cycles (resistive load), 100,000 cycles (inductive load).
  • Output Current Rating: Maximum 2.0 Amps per channel (at rated power).

Detailed Technical Specifications

  • Output Voltage Range: Supports wide load voltages: 5–24V DC, 30V AC, 125V AC, and 250V AC.
  • On-State Voltage Drop: Maximum 0.5V at 2A, 24V DC resistive load.
  • Initial Contact Resistance: Typical 30 milliohms.
  • Off-State Leakage Current: Maximum 1.5 mA.
  • Switching Speed: Output delay time (On to Off, Off to On) is maximum 10 milliseconds.
  • Isolation: Features photocoupler isolation between I/O and logic, rated at 1250V AC RMS.
  • Power Consumption: Base module dissipates max 1.2W. Each active channel draws approx. 10 mA at 28.8V DC.
  • Status Indicators: Six green LEDs provide clear visual status for each output channel.

Frequently Asked Questions (FAQ)

  • Can the 1790D-T0W6 module switch AC power?
    Yes, this relay module is designed to safely switch AC loads up to 250V AC.
  • What is the maximum switching current per relay contact?
    The maximum switching current per channel is 2.0 Amps across the specified voltage ranges.
  • Are the relays independent? How are the commons wired?
    Yes, all six relays are independent, featuring a 1 point per 1 common (1 pt/1 COM) design for flexible wiring.
  • What is the expected operational life of the module?
    Contact life expectancy is 300,000 operations under typical resistive load conditions.
  • Do you offer a return policy?
    Yes, we support a 30-day return policy for qualified products.
