IC670MDL641 Input Module - GE Fanuc

GE Fanuc IC670MDL641 48VDC 16-Point Input Module

Core Technology & Electrical Specifications

• Brand & Model: This module is manufactured by GE Fanuc. Its official part number is the IC670MDL641, belonging to the versatile Field Control family.
• Input Channels & Logic: The unit features 16 discrete input points. Each point can be configured for either positive or negative logic operation, providing exceptional wiring flexibility.
• Voltage Range & Rating: It accepts a broad input signal range of 0 to 60 Volts DC. The module's nominal and rated operating voltage is 48 VDC.
• Current Consumption: Each input point requires a low 2.5 milliamps (mA) at 48VDC from the connected field device. The module's internal draw from the Bus Interface Unit (BIU) is a maximum of 83 mA.
• On/Off State Voltage: A valid ON signal is recognized between +34 to +60 VDC (positive logic) or -34 to -60 VDC (negative logic). An OFF signal is defined as 0 to +10 VDC or 0 to -10 VDC, respectively.
• Input Impedance: Each channel has a minimum input impedance of 10 kilo-ohms (KΩ), ensuring minimal load on the sensing circuit.

Performance & Response Characteristics

• Response Time (ON): The module reacts quickly to an active signal. The turn-on response time is typically 6 milliseconds (ms), with a maximum of 10 ms.
• Response Time (OFF): Signal deactivation is also swift. The turn-off response is typically 6 ms, with a maximum of 20 ms.
• Isolation & Protection: It offers strong safety isolation, rated for 1500 VAC for 1 minute and 250 VAC continuous between field wiring and internal logic/ground.
• Current in States: The On-state current draw is very low, ranging from 0.3 mA to 3 mA. The Off-state current is negligible at 0 to 0.5 mA.
• Status Indication: The IC670MDL641 includes LED indicators to show the status of each input point and overall module power, aiding in quick diagnostics.

Frequently Asked Questions (FAQ)

• Q: Is the IC670MDL641 module new and genuine GE Fanuc?
  A: Absolutely. Every IC670MDL641 we supply is brand new, original, and sourced from authorized channels to guarantee authenticity and performance.
• Q: How soon can you ship this module?
  A: We process orders promptly, with items typically shipped within 3-5 business days after order confirmation.
• Q: What is the main difference between positive and negative logic on this module?
  A: Positive logic uses a positive voltage (e.g., +48VDC) as the ON signal, while negative logic uses a negative voltage (e.g., -48VDC). The IC670MDL641 supports both, allowing you to match existing control panel wiring conventions.
• Q: What is the response time for the inputs turning off?
  A: The off-response time for the IC670MDL641 is typically 6 milliseconds, ensuring your control system quickly recognizes when a field device deactivates.
• Q: Do you accept returns if the product does not fit my application?
  A: Yes, we offer a 30-day return policy for items in new, unused condition with original packaging. Contact our sales team for an RMA.
