Product Short Description
- Product Name: Honeywell MC-TDID52 Digital Input Module (Part No. 51304441-275)
- Product Overview: Specialized digital input module with part number 51304441-275 and model code MC-TDID52, a core component of Honeywell DCS system for collecting on-site digital switch and status signals.
- Model Series: Honeywell MC Series DCS I/O Modules
Description
- Technical Specifications:
- Model Code: MC-TDID52
- Part Number: 51304441-275
- Input Signal: Dry contact / Wet contact digital input
- Supply Voltage: 24 VDC
- Operating Temperature: 0 °C ~ +60 °C
- Channel Isolation: Galvanic isolation per channel
- Input Response Time: ≤ 6 ms
- Functional Features: Digital signal acquisition, contact state detection, channel isolation protection, overvoltage protection, fault indication, bus data transmission.
- Performance Parameters: High channel isolation strength, fast signal response, low failure rate, stable operation under strong electromagnetic environment, support long-distance signal transmission.
- Material Composition: Industrial flame-retardant housing, corrosion-resistant alloy terminals, isolated optocoupler components, reinforced PCB board, metal anti-interference shield.
- Structural Characteristics: Standard rack-mount module, integrated front status LED indicators, unified wiring terminal area, foolproof plugging design, anti-vibration fixed structure.
- Working Principle: Adopt optocoupler isolation technology to collect on-site switch state signals, convert discrete switch signals into digital data recognized by DCS main controller, and transmit data through system bus; each channel uses independent isolation circuit to ensure system safety.
- Advantages & Highlights: Professional optocoupler isolation design, strong anti-interference capability, high operational reliability, perfect matching with Honeywell DCS system, convenient field maintenance.
- Applicable Industries: Electric power, petrochemical, metallurgy, coal chemical, water supply & drainage, industrial automatic production lines.
- Installation Requirements: Install on Honeywell standard DCS rack; ensure good cabinet ventilation; distinguish dry/wet contact wiring strictly per manual; module must be fully locked after installation.
- Usage Notes: Live plugging is prohibited; regularly check terminal wiring tightness and insulation; keep module away from flammable and corrosive substances; replace damaged modules with same model only.
