【英文介绍】

The IC670ALG230 is an analog input module from GE Fanuc. It specifically belongs to the Field I/O control product family of expansion modules that operate with a compatible Bus Interface Unit (BIU). This module primarily features Eight (8) Analog input channels that accepts 0-20 mA and 4-20 mA analog input signals. This module is mainly used for interfacing of field signal transmitters of many types, outputs of panel meters, data loggers, signal splitters, Variable Frequency Drives (VFD) and similar devices.

The IC670ALG230 has analog resolution of 5.0 µA while the digital resolution is 12 bits, typical. It accepts a minimum input current of 0.1 mA and maximum of 20 mA. It is built with internal protection features such as open wire detection and over-range fault detection.

The IC670ALG230 has built-in analog to digital converter (ADC) circuit which converts the received analog signal to digital format for processing of the host CPU. The ADC circuit has a conversion time of 60 µs per channel at 1 MHz module clock. It also has a 1st order RC input filter with typical transition capacity of 160 Hz.

This module has non-linearity of +/- 25% of Full Scale and temperature coefficients of +/–.002% of value per degree C, typical and +/–.005% of value per degree C, maximum. This module comes with a single group of input channels and supports single-ended wiring configuration. Each channel has ground and logic isolation rated 1500 VAC for 1 minute and 250 VAC, continuous. It has a rated current draw of 51 mA, maximum from the BIU power supply.

The IC670ALG230 input module is an 8-channel input module manufactured by GE Fanuc. It can run with a common power supply. It is powered with a 24 Volts power supply that also powers the bus interface unit. In case of isolation, a separate power supply is used. The front of the module has LED indicators that show the operation of backplane and the field power. The input module is used to drive different isolated transducers and inputs by using a local power supply. No isolation is present between individual points that are in a group. The isolation to case rating is 250 Volts AC for a continuous time period, and isolation to ground is 1500 Volts AC for a time period of 1 minute. The input impedance of the module is 2.87 kiloohms. The on-state voltage is between 15 Volts DC and 30 Volts DC, and the off-state voltage is between 0 and 5 Volts DC.
