DS200TCQCG1BGF Gas turbine electrical module

The IMFEC12 High Level Analog Input (FEC) module inputs 15 channels of analog signals only to the multifunction processor (MFP) or multifunction controller (MFC) module. The IMFEC11 High Level Analog Input (FEC) module inputs 15 channels of analog or frequency shift keyed (FSK) digital signals to the MFP or MFC module. The IMFEC11 module performs all the functions of the IMFEC12 module and also provides communication with the Bailey-Fischer & Porter line of FSK digital smart transmitters and other smart devices in a field bus or point-to-point configuration. Figure 1-1 shows how the FEC module fits within the INFI 90 OPEN system.

INTENDED USER

 Installation and application personnel should have a solid background in electronic instrumentation and process control. They should be familiar with proper grounding and safety procedures for electronic instrumentation. Operators should have a knowledge of the process and should read and understand this instruction before placing the module in operation.

HARDWARE DESCRIPTION

 The 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.
