FAQ – Frequently Asked Questions

• What is the maximum load resistance?
  • 750 ohms. Exceeding this may reduce output accuracy.
• Can I calibrate each channel individually?
  • Yes. Field calibration is stored per channel in non-volatile memory.
• What does the red LED indicate?
  • Module or channel diagnostic fault. Check wiring, supply, and calibration.
• How many modules fit in one rack?
  • 10 standard; up to 12 with ambient temperature derating.
• Is the output isolated from logic?
  • Yes, 600 VDC isolation from logic, and 500 VDC between channels.
• What if communication to the controller is lost?
  • User-defined failsafe values ensure safe, predictable output.
• How fast are outputs updated?
  • Synchronous with control execution – real-time updates.
• Can I limit the rate of change?
  • Yes. A user-specified ramp limit can be applied per output.
• What wire gauge is recommended?
  • Use 0.5 – 1.5 mm² (20–16 AWG) stranded copper wire.
• Is this module suitable for safety-critical loops?
  • For SIL applications, consult Honeywell safety manuals.

Selection Guide – Which Output Module Do You Need?

• For standard 4–20 mA loops: 900B01-0101 is ideal, but check your load.
• For high-density applications: Use 4 channels per module, max 10 per rack.
• For extreme temperatures: Ensure ambient ≤60 °C or derate for 12 modules.
• Budget vs. performance: This module balances cost with 12-bit accuracy and isolation.
• Always verify: Power supply capacity (5V/40mA, 24V/200mA per module).
