Frequently Asked Questions about 1734-IB8
Question: What is the input configuration of the 1734-IB8 module?
Date Update:23/05/2025
Answer:

The 1734-IB8 module is designed for sinking input configuration. This means that each input channel connects to a 24V DC source, and the module detects the current flowing through the input when the connected device pulls the input to ground. It is important to note that this module is not compatible with sourcing inputs.

Question: What is the voltage and current range for the inputs?
Date Update:23/05/2025
Answer:

The module operates with the following input specifications:

  • Input Voltage Range: 10–28.8V DC
  • On-State Voltage: Minimum 10V DC
  • Off-State Voltage: Maximum 5V DC
  • On-State Current: 2–5 mA
  • Off-State Current: Maximum 1.5 mA
  • Nominal Input Voltage: 24V DC
Question: What are the power and thermal characteristics of the module?
Date Update:23/05/2025
Answer:

The 1734-IB8 module has the following power and thermal specifications:

  • Power Dissipation: 1.6 W (5.5 BTU/hr)
  • Maximum Input Current: 5 mA
  • POINTBus Current Draw: 75 mA at 5V DC
  • Isolation Voltage: 50V DC continuous, reinforced insulation type tested at 2500V DC for 60 seconds
Question: What are the environmental and mounting requirements?
Date Update:23/05/2025
Answer:

The module is designed to operate under the following conditions:

  • Operating Temperature: 0°C to 60°C (32°F to 140°F)
  • Storage Temperature: -40°C to 85°C (-40°F to 185°F)
  • Relative Humidity: 5% to 95% non-condensing
  • Enclosure Type: Open-style (IP20)
  • Mounting: DIN rail mounting using a 1734-TB or 1734-TBS terminal base
Question: How does the module handle input filtering and diagnostics?
Date Update:23/05/2025
Answer:

The 1734-IB8 module includes:

  • Input Filter Time: 0.5 ms hardware plus 0–63 ms user-selectable
  • Status Indicators: LED indicators for each input channel and one for module status
  • Diagnostics: Provides feedback on input status and module health
