Allen-Bradley 1790-16BV0X 24V DC 16-Point Universal Input Module

Allen-Bradley 1790-16BV0X 24V DC 16-Point Universal Input Module

Key Input Specifications & Electrical Data

• Brand & Model: This is an authentic Allen-Bradley product, part of the versatile 1790 series, model 1790-16BV0X.
• Input Type & Count: The module offers 16 universal input points. Each point can be configured as either sinking or sourcing.
• Voltage Levels: It recognizes an input signal as ON at 9.6V DC minimum and OFF at 5.0V DC maximum. The nominal input voltage is 24V DC.
• Current & Impedance: Each channel draws a maximum of 8 mA when on. The typical input impedance is 4.8 kΩ.
• Isolation & Safety: Photocoupler isolation between I/O and logic provides 1250V AC RMS protection for your control system.

General Module Specifications & Wiring

• Power Supply: The module's DeviceNet interface requires a 24V DC nominal power source, operable from 11V to 28.8V DC.
• Power Consumption: Total power dissipation remains under 1.2 Watts maximum at the highest voltage.
• Wiring & Common Groups: All field connections use a sturdy 37-pin D-shell connector. Inputs are grouped into eight commons, with two points sharing one COM.
• Visual Indicators: Sixteen individual green LED status indicators provide immediate visual confirmation of each input's state.

Data Mapping & Communication

• The 1790-16BV0X module produces three words of data over the DeviceNet network for clear status reporting.
• Produces Word 0 (Bits 00-07): This byte contains general status information for the module itself.
• Produces Word 1 (Bits 08-15): These bits directly represent the state of physical inputs I0 through I7. A set bit (1) means the corresponding input is ON.
• Produces Word 2 (Bits 16-23): These bits directly represent the state of physical inputs I8 through I15. A set bit (1) means the corresponding input is ON.

Frequently Asked Questions (FAQ)

Q: What does "universal input" mean for the 1790-16BV0X?

A: It means each of the 16 input points can accept either a sinking (NPN) or sourcing (PNP) 24V DC signal without requiring hardware changes.

Q: How are the input points grouped or wired?

A: The inputs are arranged in 8 groups of 2 points. Each group shares a common (COM) terminal, allowing flexible wiring for different field device types.

Q: What is the operating voltage range for the inputs?

A: The input circuitry recognizes a valid ON signal from 9.6V DC up to 28.8V DC. Signals below 5V DC are recognized as OFF.

Q: What is your return policy for this input module?

A: We offer a straightforward 30-day return policy for items in new, unused condition with original packaging.
