O proizvodu

Allen-Bradley 1790D-0W6 6-Relay Output Module Product Introduction

Key Technical Specifications

  • The 1790D-0W6 features six Form A (normally open) relays with single pole, single throw configuration.
  • Each relay can switch 2.0A at 5-28.8V DC or 2.0A at 30V AC with resistive loads.
  • The module has a low on-state voltage drop of 0.5V maximum at 2.0A, 24V DC.
  • Initial contact resistance is only 30 mΩ for efficient power transmission.
  • Relay switching delay times are 10 ms maximum for both off-to-on and on-to-off transitions.

Power Requirements & Wiring

  • The module operates with a DeviceNet power supply rated at 24V DC nominal (11-28.8V DC range).
  • Field power supply requires 19.2-28.8V DC for proper relay operation.
  • Each channel has independent common terminals (1 point/1 COM) for wiring flexibility.
  • All connections utilize a standard 37-pin D-shell connector for secure installation.
  • The module has a maximum power dissipation of 1.2W from DeviceNet power.

Relay Performance & Durability

  • The relays offer photocoupler isolation with 1250V AC RMS rating between I/O and logic circuits.
  • Expected contact life is 300,000 cycles for resistive loads and 100,000 cycles for inductive loads.
  • Each channel features green LED status indicators for immediate visual feedback.
  • Minimum load requirement is 100 µA at 100 mV DC per input channel.
  • Off-state leakage current is limited to 1.5 mA maximum for energy efficiency.

Frequently Asked Questions (FAQ)

  • Q: What type of relays does the 1790D-0W6 module use?
    A: The module uses six Form A (normally open) SPST relays with independent contacts.
  • Q: What voltage and current can these relays switch?
    A: Each relay can switch up to 2.0A at 5-28.8V DC or 30V AC with resistive loads.
  • Q: What is the expected lifespan of the relays?
    A: The relays are rated for 300,000 cycles with resistive loads and 100,000 cycles with inductive loads.
  • Q: Does this module support both AC and DC loads?
    A: Yes, the 1790D-0W6 can switch both DC (5-28.8V) and AC (30V) loads up to 2.0A.
  • Q: What is your shipping and return policy?
    A: We ship within 5 days via major carriers and offer a 30-day return policy for customer satisfaction.
