Description

The IMFEC11 FEC module is an intelligent module, with on-board microprocessor, memory, analog-to-digital converter and communication circuitry. The module is a single printed circuit board that occupies one slot in a module mounting unit (MMU). Two captive latches on the module faceplate secure it to the module mounting unit. The module has three card edge connectors for external signals (transmitter inputs and communication), system communication (I/O expander bus) and power. The module receives input through a cable connection to a termination unit (TU) or termination module (TM). Wiring from the field devices connect to terminal blocks on the termination unit or termination module. The IMFEC11 circuit board has 18 jumpers; three jumpers that allow selecting the mode of operation and communication (J2, J3 and J4) and 15 jumpers that select voltage/current input (J6 through J20). A dipswitch setting (S1) holds the I/O expander bus address of the module. The IMFEC12 circuit board only uses one working setting, dipswitch S1 that holds the I/O expander bus address of the module. Jumpers J2 through J4 and J6 through J20 are not used.

Applications

Large Power Plants: Used to monitor critical analog parameters (such as pressure, flow rate, and temperature) of boilers, turbines, and generator sets.

Integrated with smart transmitters for remote calibration and equipment diagnostics, reducing the need for manual on-site maintenance.

Oil & Gas Processing Plants: Used in refineries and gas processing stations to accurately acquire 4-20 mA signals.

In flammable and explosive environments, its highly reliable isolation design monitors tank levels and pipeline pressures.

Chemical & Petrochemical Facilities: Plays a role in reactor control and distillation column monitoring, ensuring precise regulation of complex chemical reaction processes.

Water & Wastewater Treatment Plants: Monitors the operational status of pump houses, filters, and dosing systems.

Pulp, Paper & Mining Plants: Used for sensor data integration on continuous production lines, ensuring the continuity of material handling and processing.

FEATURES

The design of the FEC module, as with all INFI 90 OPEN modules, allows for flexibility in creating a process management system. The module supports Bailey-Fischer & Porter FSK digital smart transmitters and other smart devices, conventional transmitters and standard voltage or current inputs.

The FSK digital capability (IMFEC11) eliminates conversion errors and increases process control accuracy. Access is always available to the real time process status. In the field bus mode, all information (including the process variable) is transmitted digitally between the FEC module and the field devices.

The FEC module stores process data, control commands and transmitter configuration data in memory. It works to restore communication with a transmitter if a communication failure occurs. Upon restoring communication with a failed transmitter, the FEC module checks the transmitter configuration before the control module (MFP/MFC) resumes updating the process control.

HARDWARE APPLICATION

The IMFEC11 FEC module interfaces analog and digital signals from field devices to the MFP or MFC module. The IMFEC11 module can interface Bailey-Fischer & Porter FSK smart transmitters and other smart devices. The IMFEC12 is for use with conventional transmitters (BC, EQ and PT) and standard analog inputs.

The IMFEC11 module can operate in one of two modes: FSK field bus mode or FSK analog point-to-point mode. In the FSK field bus mode, a single two-wire input (bus) links a maximum of 15 FSK smart transmitters. All inputs (process data and module to transmitter communication) are in the frequency shift keyed format and share the field bus. Refer to the NTFB01 Field Bus Termination Unit instruction for specific limitations on field bus communications. All field devices must be Bailey-Fischer & Porter when using this mode. In the FSK analog point-to-point mode, the IMFEC11 module can interface up to 15 discrete analog process inputs from FSK smart devices and communicate (digitally) with those devices. Additionally, the IMFEC11 module can interface a mixture of conventional transmitters and other external analog inputs while operating in this mode. These devices can input only process data to the FEC module; they cannot communicate to the module. In point-to-point operation, each device is individually wired to the analog input termination unit or module.
