METSO D200536
Technical Specifications: 16‑channel analog input; support 4‑20 mA current and 0‑10 V voltage signal; 16‑bit A/D conversion resolution; per‑channel galvanic isolation 1500 VAC; backplane 24 VDC power supply; rack plug‑in installation; operating temperature range 0 ℃‑+55 ℃; each channel LED indicator; protection class IP20.
Functional Features: Differential analog signal acquisition; per‑channel electrical isolation restrains ground‑loop interference; hardware open‑circuit and over‑range detection; single‑channel fault isolation; module self‑diagnosis; upload measured value and fault‑alarm information to DCS upper monitoring workstation.
Application Scenarios: Chemical plant reaction device parameter‑acquisition cabinet; thermal power plant boiler auxiliary instrument‑signal cabinet; pulp and paper mill process transmitter signal cabinet; mining process monitoring cabinet.
Performance Parameters: Full‑scale measurement accuracy ≤±0.1 %; low long‑term zero drift; stable signal transmission for long‑distance field wiring; conform to industrial EMC anti‑interference standards; support 7×24 hours uninterrupted running.
Material Composition: Fiberglass epoxy multilayer PCB; high‑precision A/D conversion chip; optoelectronic isolation components; gold‑plated backplane edge connector; metal front panel; three‑proof conformal coating on circuit‑board surface.
Structural Features: Rack plug‑in modular card‑type structure; front panel integrates LED indicators for power‑on, running and channel fault status; rear gold‑plated connector mates with rack backplane; analog acquisition circuit and digital logic circuit achieve physical isolation; mechanical anti‑loose buckle fitted on front panel.
Working Principle: Field analog signals pass matched terminal base and enter D200536 module. Signals go through isolation circuit and send to A/D conversion unit. Analog physical‑quantity converts into digital numerical value. Digital data transmits to DPU controller via backplane bus. Module continuously monitors each input‑loop state, identifies open‑circuit, short‑circuit and over‑range faults, lights corresponding indicator and sends alarm information to upper system.
Installation Requirements: Install D200536 into designated slot of Damatic XD I/O rack and use matched terminal base. Adopt twisted‑pair shielded cables for analog‑signal wiring. Cable shielding layer applies single‑point grounding. Signal cables and high‑power cables are laid in separate trunking. Guarantee reliable connection of cabinet protective grounding terminal. Reserve adequate ventilation clearance for heat dissipation.
Precautions for Use: Verify signal polarity before power‑on operation. Cut off field transmitter loop power before wiring. Never feed high‑voltage signal into analog input channel. Wear anti‑static wrist strap when touching circuit‑board components. Inspect wiring‑terminal tightness periodically. Keep cabinet humidity within 20 %‑80 % without condensation.
