Analog Input Module | IMFEC11 | ABB

Technical Specifications

The digital interface, made up of the IMFEC11 module and the controlling module, provides a communication path between an INFI 90 OPEN operator interface and Bailey-Fischer & Porter smart transmitters. Commands can be sent from an operator interface to change transmitter parameters or to rerange a transmitter output. In return, the transmitters send process and status data to the operator interface through the FEC module and controlling module (MFP/MFC). The controlling module communicates with the FEC module over the I/O expander bus. The IMFEC11 module must use the NTFB01 termination unit to terminate FSK digital smart transmitters on a field bus. All inputs must be in an FSK digital field bus mode when using the NTFB01 termination unit. There are no other input types available when operating in this mode.

Troubleshooting & Comissioning Checklist

Physical Inspection: Inspect the faceplate, alignment pins, and rear backplane connectors for structural damage or bent pins.
Dip Switch Configuration: Confirm that the module address and hardware operating parameters match the design engineering documents.
Grounding Continuity: Check that the module rack chassis or DIN rail assembly maintains structural grounding continuity.

Field Engineering Considerations

FSK Analog Point-to-Point Mode: Connects up to 15 independent analog loop signals. Digital communication occurs point-to-point with individual smart transmitters to adjust parameters or update data 3 to 10 times per second.
FSK Field Bus Mode: Configures the module to act as a multidrop digital fieldbus interface. This mode can directly replace legacy IMFBS01 fieldbus modules. However, note that baseband communications are not supported.
Connection Routing: Field instrumentation terminates at the TU terminal block, which routes back to the Module Mounting Unit (MMU) slot backplane via a specialized ribbon cable.

Technical FAQ

Q: Is the IMFEC11 a communication module or an analog input module?
A: It serves both functions. It performs standard industrial analog signal acquisition while transmitting data via Frequency Shift Keying (FSK) communication protocol.

A: While both modules share the same hardware analog input capabilities, the IMFEC11 additionally provides active digital communication capabilities with ABB’s line of FSK-based digital smart transmitters and field devices.

A: No. Ethernet or newer networking capabilities referenced by parts brokers are managed through external infrastructure or network interface gates, not the legacy IMFEC11 hardware layout itself.

Q: Do you supply brand-new, original parts or second-hand refurbished items?

A: Our stock consists of Original New items; all products undergo quality inspection to ensure they are fully functional.

Q: What guarantees are included with the shipment?
A: All items in stock are tested by engineers, packed in professional ESD packaging, and shipped via express logistics with a global delivery time of 24–48 hours.

Q: How long does global shipping take?
A: Stock items are typically dispatched within 24 hours. Shipments are sent via DHL or FedEx Express, taking approximately 3–5 days to reach Asia, 4–6 days to Europe and the Middle East, and usually arriving within a week in major industrial regions worldwide.

Q: If the model I need is not listed on the website, can I request a quote?
A: Yes. We hold over 200,000 SKUs of industrial spare parts in stock, and many long-tail models are not listed in full. You can send us an RFQ (Request for Quote) directly, and we will provide wholesale pricing promptly.
