【英文介绍】

The IC670ALG240 is GE Fanuc's analog input module. The module is part of a family of field I/O controls designed for installation along bus interface units (BIUs) and extension racks. The module provides sixteen (16) analog input channels in a single group, accepts current input signals in the form of 0-20 mA and 420 mA, and can operate in the input signal range of 0-25 mA.

The IC670ALG240 can be used to connect field transmitters such as pressure, level, flow, temperature, turbidity and similar types. It can also be used to connect output signals from panel meters, data loggers, single loop controllers, variable frequency drivers (VFDS), signal splitters, signal isolators, and other devices. The module comes with a built-in analog-to-digital converter (ADC) that can be used for each input channel to convert analog data into a digital format with a resolution of 16 bits.

The maximum current consumption of the IC670ALG240 is 251 mA for the BIU supply. It operates in a temperature range of 0-55 degrees Celsius and requires a current loop supply of 20-28 VDC with a nominal ripple voltage of 10%. Its temperature coefficient is usually +/-.002% per degree Celsius value, with a maximum value of +/-.005% per degree Celsius value. The module supports ANSI Type 2 2-wire transmitter and Type 3 3-wire transmitter wiring configurations.

The IC670ALG240 is capable of performing internal diagnostics such as module not calibrated, calibration data out of range, calibration write failure, ready calibration, command invalid, A/D conversion not completed, factory calibration unavailable, single channel high and low alarm, underrange and overrange conditions.

GE IC670ALG240 input module is a 16-channel analog current input module. The module is capable of receiving 16 loop inputs at a time using a common power supply. The module is capable of accepting a 2-wire or 3-wire current transmission and then converting it into a digital input value. The input current range of the module is 0 to 25 MA. This module supports both word and bit data types. The IC670ALG240 input module can be easily calibrated and the calibration data is stored in flash memory. The module uses 50 Hz and 60 Hz frequencies for data acquisition. The module is intelligent, with diagnostic and alarm functions, and can report overrange and open circuit alarms. Alarms in the module can be configured by the operator.

The GE Fanuc IC670ALG240 input module has a resolution of 16 bits. The 16-bit input current ranges between 0 and 25 mA. The module's current loop supply is between 20 and 28 volts, with a maximum ripple of 10%. For operation, the temperature should be set between 0 and 55 degrees Celsius. The IC670ALG240 input module uses a second-order active RC filter as the hardware filter. The common mode rejection from channel to ground is 2 dB. The input module has several useful functions. It comes with a channel activity mode that helps to set a specific channel to active or inactive. It has advanced filtering options such as input filters, line filters, and average filters.
