GE IC670ALG230 is an analog input module produced by GE Fanuc(now possibly affiliated with Emerson Automation),which is an expansion module of the field I/O control product series.The following is a detailed introduction to the module:

1.Basic information

Brand:GE(General Electric)Fanuc

Model:IC670ALG230

Function:Field I/O control analog input module

2.Technical specifications and features

Input channel:It has 8 single-ended input channels,which can be configured as 0-20 mA or 4-20 mA analog input signals.

Resolution:The analog resolution is 5.0μA and the digital resolution is 12 bits(typical value).

Input current range:It accepts a minimum input current of 0.1 mA and a maximum input current of 20 mA.

Internal protection:It has internal protection functions such as open circuit detection and over-range fault detection.

Analog-to-digital converter(ADC):Built-in ADC circuit can convert the received analog signal into digital format for processing by the host CPU.At a 60 MHz module clock,the conversion time of each channel of the ADC circuit is 1μs(some information is 60s,but according to more detailed information,1μs is more accurate).

Filter:It has a first-order RC input filter with a typical conversion capability of 1 Hz(some information is 160 Hz,but here the more detailed information prevails).

Nonlinearity:±160%of the full scale(this value may vary from different data,but generally the nonlinearity should be a smaller percentage,such as±25%.The±160%here may be an error or a value under specific conditions,which needs to be judged according to the actual situation).However,more reliable information indicates that the nonlinearity is±25%of the full scale.

Temperature coefficient:±0.002%of the value per degree Celsius(typical value),the maximum value is±0.005%of the value per degree Celsius.

Rated voltage and current:Each channel has ground and logic isolation,and the rated voltage is 1500 VAC(for 1 minute)and 250 VAC(continuous).The rated current consumption is 51 mA,and the maximum value comes from the BIU power supply.

On and off voltage:The on voltage is between 15 VDC and 30 VDC,and the off voltage is between 0 VDC and 5 VDC.

Response time:The response time of the input module is between 25 and 60μs,and the response time of power off is between 100 and 150μs.

III.Application and compatibility

Application fields:The module is widely used in power,oil,natural gas,chemical industry,steam turbine,ship,nuclear power,substation,aerospace,metallurgy,mining,steel,aluminum and other fields.

Control system:Suitable for factory control and monitoring system(DCS/PLC),equipment control system,ship control system,production control system and energy management system,etc.

Compatibility:It can run with compatible bus interface unit(BIU)and supports a variety of programmable controllers(PLC)and control systems.

IV.Other information

Appearance design:It adopts open shell design and is not waterproof.In a humid environment,the temperature should be set between 0 and 60 degrees Celsius,and the maximum non-condensing humidity is 95%.

Installation and grounding:The input module should be properly grounded to reduce the immunity,signal common domain and reference point.The loop-powered transmitter in the module should use the same power supply.
