O proizvodu

Allen-Bradley 1790-0V16X Sinking Output Module

Core Technical Specifications

  • Brand & Model: Allen-Bradley 1790-0V16X.
  • Output Type: 16-point, non-isolated, sinking configuration.
  • Output Current: Rates at 0.5 Amps maximum per point and 4.0 Amps maximum per common group.
  • Voltage Range: The on-state voltage operates from a 10V DC minimum to 28.8V DC maximum, with a nominal 24V DC.
  • Switching Speed: Features a fast output signal delay (Off to On: 0.5 ms max, On to Off: 1.0 ms max).
  • Voltage Drop: Ensures minimal power loss with an on-state voltage drop of 0.5V DC maximum.
  • Isolation: Provides photocoupler isolation (I/O to logic) rated at 1250V AC RMS for safety.
  • Power Consumption: DeviceNet power dissipation is 1.2W max; field power uses 6 mA per point at 28.8V DC.

Frequently Asked Questions (FAQ)

  • Q: What is a "sinking" output on this module?
    A: A sinking output means the module acts as a path to ground (GND). You connect your load (like a solenoid) to the +24V supply, and the module switches the ground connection on/off.
  • Q: How many outputs can I activate at the same time?
    A: Each output can handle 0.5A. However, you must not exceed 4.0A total for each common group (COM). The 1790D-OV16 base unit groups outputs as 8 points per 2 commons.
  • Q: What is the minimum current needed for each output to turn on?
    A: The module requires a minimum on-state current of 1 mA per channel for stable operation.
  • Q: Is there any protection between the logic and field power?
    A: Yes. The module features photocoupler isolation rated at 1250V AC RMS between the I/O circuits and the internal logic.
  • Q: Are the status indicators easy to see?
    A: Yes. Each of the 16 output points has a dedicated green LED status indicator for clear visual diagnostics.
