Allen-Bradley 1790-T0W8X 8-Channel Relay Output Module

Key Technical Specifications

  • The Allen-Bradley 1790-T0W8X features eight Form A (normally open) relays.
  • Each relay is a single pole, single throw (SPST) type for straightforward switching.
  • The module handles a wide output voltage range from 5 to 28V DC at 2.0A.
  • It also supports AC loads up to 250V AC at 2.0A for resistive conditions.
  • The minimum load requirement is a low 100 µA at 100mV DC per channel.
  • Expect a maximum on-state voltage drop of 0.5V at 2.0A with a 24V DC load.
  • Initial contact resistance is very low at just 30 mΩ.
  • Relay contact life is rated for 300,000 cycles (resistive) and 100,000 cycles (inductive).
  • Maximum off-state leakage current is 1.5 mA for minimal power waste.
  • Output delay time is a fast 10 ms maximum for both turn-on and turn-off.

General Specifications & Design

  • The module requires a nominal 24V DC field power supply (19.2 to 28.8V DC range).
  • Power dissipation is approximately 2.3W per channel at the maximum voltage.
  • It features photocoupler isolation between I/O and control logic.
  • The isolation voltage rating is a high 1250V AC RMS for safety.
  • Wiring uses a terminal block (M3.0) with a max torque of 7 lb-in.
  • Eight green LED status indicators provide clear channel state feedback.
  • The common type configuration is 1 point per 1 common (1COM).
  • Its compact design weighs only 0.38 lbs (0.17 kg).

Frequently Asked Questions (FAQ)

  • Q: Is this module brand new and original?
    A: Yes, we supply only 100% brand new and original Allen-Bradley modules.
  • Q: What is the switching capacity of each relay?
    A: Each relay can switch up to 2.0A at 28V DC or 250V AC for resistive loads. Check specs for inductive loads.
  • Q: What type of relay contacts does it have?
    A: It uses Form A (Normally Open) Single Pole, Single Throw (SPST) relay contacts.
  • Q: How is the module powered?
    A: It requires an external 24V DC nominal (19.2-28.8V DC) field power supply.
  • Q: Do you have this module in stock?
    A: Yes, the 1790-T0W8X is typically available from our stock for fast delivery.
  • Q: What is the expected life of the relays?
    A: The relays have an expected life of 300,000 cycles with resistive loads.
  • Q: What is your shipping and returns policy?
    A: We ship within 5 days via major carriers and support a 30-day return policy for your peace of mind.
