Applicable Industries:

• Oil & Gas — Control valve positioning, VFD speed control
• Chemical & Petrochemical — Precise flow and pressure control
• Power Generation — Boiler damper control, feedwater regulation
• Water & Wastewater — Pump speed control, chemical dosing
• Pulp & Paper — Basis weight control, consistency control

Installation Requirements:

• Mount on F3 series main rack (F3B-20HR or equivalent)
• Use shielded twisted-pair cable for all analog output wiring
• Maximum cable length: 200 m (for 4–20mA, with shielded cable)
• Ensure loop power supply voltage ≥ 18 VDC (accounting for load resistance)
• Ground the cable shield at controller end only

Precautions:

• Do not exceed 24 mA per channel — will damage output circuit
• Do not apply voltage > 30 VDC across any output terminal
• Calibrate all channels during initial commissioning and annually thereafter
• Do not hot-swap the module — power down the PLC before insertion/removal
