Information About IC670ALG240

The IC670ALG240 is an analog input module from GE Fanuc. This module is specifically part of the Field I/O control series that is designed for installation along a Bus Interface Unit (BIU) and an expansion rack. This module provides Sixteen (16) analog input channels in a single group, accepting current input signals in the form of 0-20 mA and 420 mA and may be operated at an input signal range of 0-25 mA.

The IC670ALG240 can be used to interface field transmitters such as Pressure, Level, Flow, Temperature, Turbidity and similar types. It may also be used to interface output signals of panel meters, data loggers, single-loop controllers, Variable Frequency Drives (VFD), signal splitters, signal isolators and other devices. This module comes with a built-in Analog to Digital Converter (ADC) available to each input channels that converts the analog data to digital format with resolution of 16-bits.

The IC670ALG240 has a maximum current draw of 251 mA from the BIU power supply. It has an operating temperature range of 0-55 Degree Celsius and requires a current loop power supply 20-28 VDC, nominal with 10% ripple voltage. It has temperature coefficient of +/-.002% of value per degree C, typical, and +/-.005% of value per degree C, maximum. This module supports ANSI Type 2 2-wire transmitter and Type 3 3-Wire transmitter wiring configuration.

The IC670ALG240 is capable of performing internal diagnostics such as module not calibrated, calibration data out of range, calibration write failure, ready to calibrate, invalid command, A/D conversion incomplete, Factory calibration not available, individual channel high and low alarm, underrange and overrange conditions.

The GE IC670ALG240 input module is a 16-channel analog current input module. At a single time, the module is able to take in 16 loop inputs by using a common power supply. The module is able to accept 2-wire or 3-wire current transmissions and then change them into digital input values. The input current to the module ranges between 0 and 25 milliamps. The module supports both the word and bit data types. The IC670ALG240 input module can be easily calibrated and the calibration data can be stored in the flash memory. The module uses 50 Hertz and 60 Hertz frequencies for data acquisition. The module is intelligent and it comes with diagnostics and alarm features that can report over range and open wire alarms. The alarms in the module can be configured by the operators.

The GE Fanuc IC670ALG240 input module has a resolution of 16 bits. The input current span for 16 bits ranges between 0 and 25 milliamps. The current loop power supply of the module is between 20 and 28 Volts, and it has a maximum ripple of 10%. For operation, the temperature should be set between 0 and 55 degrees Celsius. The IC670ALG240 input module uses an active RC filter 2nd order as the hardware filter. The common mode rejection from the channel to the ground is 86 dB. The input module has several useful features. It comes with the Channel Active mode that helps to set a specific channel as active or inactive. It has advanced filtering options like the input filter, line filter, and averaging filter.

Maintenance Tips

• Visual Inspection: Regularly inspect the module for visible signs of damage, such as burnt components, broken traces, or loose connectors. Pay close attention to the input and output terminals.

• Clean the Module: Use dry compressed air or an anti-static brush to remove dust, dirt, or debris. Avoid using liquid cleaners that could damage sensitive components or cause short circuits.

• Verify Input and Output Signals: Ensure that the input and output signals fall within the recommended voltage ranges. Incorrect voltage levels can cause erroneous readings or malfunctioning of the field control module.

• Inspect Connectors and Wiring: Check connectors for proper attachment, cleanliness, and signs of wear or corrosion. Loose or corroded connections can cause intermittent signal failures or data loss.

• Check Solder Joints: Inspect solder joints for cracks, corrosion, or poor connections. Cold solder joints can lead to unreliable performance or intermittent issues.

• Run Diagnostics: Use diagnostic tools or software to test the module’s functionality. Look for any error codes or abnormal behavior that could indicate an issue with the module or wiring.

• Monitor Power Supply: Ensure the module is receiving the correct input power supply. Voltage fluctuations or incorrect power levels can lead to instability or damage to the module.

• Temperature Monitoring: Confirm that the module operates within the specified temperature range. Overheating can damage the components and reduce the module’s lifespan.

• Check Grounding: Ensure that the module is properly grounded to prevent electrical noise or interference, which could impact signal quality and accuracy.

• ESD Protection: Handle the module with proper electrostatic discharge (ESD) precautions, such as wrist straps and anti-static mats, to protect sensitive components from damage.
