  • Nickel/Iron: 604 ohms (518, 527 standards)
  • Direct Resistance: 0–500 ohms, 0–3000 ohms

LED Indicators

  • FLD PWR (Green): Indicates presence of both backplane power and field power

  • OK (Green): Normal operation

  • OK (Flashing Green): Boot mode or firmware update

  • OK (Flashing Amber): Self-diagnostic error

  • OK (Off): No 3.3V backplane power

Diagnostics Over/under range, open wire, input short, non-volatile memory storage fault, wiring fault, and high/low alarm. The module automatically performs A/D calibration at power-up and periodically thereafter to compensate for temperature changes.
