Applicable Industries:
Oil & gas (custody transfer), power generation (turbine speed), water/wastewater (flow metering), mining, pulp & paper

Installation Requirements:

• Install in Ovation I/O rack (chassis slot or DIN rail)
• Use shielded twisted pair for pulse inputs, max 100 m cable length at 100 kHz
• For dry contact inputs: debounce time must be set ≥1 ms
• Ground shield at controller end only
• Do not apply voltage exceeding 30 V DC to any input

Usage Notes:

• Maximum input frequency: 100 kHz (do not exceed)
• For quadrature encoding, use shielded twisted pair with A/B phase wires twisted together
• Configuration via Emerson DeltaV / Ovation Workstation software
• Replace only with Emerson 5X00321G01 or approved equivalent
• Calibration per IEC 61508 schedule (typically every 24 months)
