The IC670ALG230 has a built-in analog-to-digital converter (ADC) circuit that converts received analog signals into digital format for processing by the host CPU.

The ADC circuit has a conversion time of 1 μs per channel at a module clock of 60 MHz. it also has a first-order RC input filter with a typical conversion capability of 1 Hz.

The module has a nonlinearity of +/- 160% of full scale, a temperature coefficient of +/-.25% per Celsius value, a typical value of +/-.002% per Celsius value, and a ** value of +/-.002% per Celsius value.

**value of +/-.005% per degree Celsius value. The module comes with a single set of input channels and supports single-ended wiring configurations.

Each channel has ground and logic isolation and is rated at 1500 VAC for 1 minute and 250 VAC.

It has a rated current consumption of 51 mA** from the BIU power supply.

The IC670ALG230 input module is an 8-channel input module manufactured by GE Fanuc.

It can be operated with a universal power supply. It is powered by a 24-volt power supply that also powers the Bus Interface Unit.

In the case of isolation, a separate power supply is used. There are LED indicators on the front of the module that show the operation of the backplane and the field power.

The input module is used to drive the different isolated sensors and inputs using the local power supply. There is no isolation between points in the group.

Isolation is rated at 250 volts AC to the enclosure and 1500 volts AC to ground for a continuous period of 1 minute.

The input impedance of the module is 2.87 kohms. turn-on voltage is between 15 and 30 volts dc, and turn-off voltage is between 0 and 5 volts dc.

The response time of the IC670ALG230 input module is between 25 and 60 us, and the power-down response time is between 100 and 150 us.

This module draws 100 mA of current from the bus interface unit. Output keying in this module can be used to mix inputs and outputs.

The input module should be properly grounded to reduce immunity, signal co-domain, and reference points. The loop powered transmitters in the module should use the same power supply.

Frequently Asked Questions about 745-W2-P15-G1-LO-A-R

What is the FlexLogic feature included with the General Electric Multilin 745-W2-P15-G1-Lo-A-R Transformer Protection System?

The FlexLogic of the 745-W2-P15-G1-Lo-A-R Transformer Protection System allows the unit to compute PLC equations by using logical inputs and protection elements that can be adapted to any output.

What options does the General Electric Multilin 745-W2-P15-G1-Lo-A-R Transformer Protection System have?

The General Electric Multilin 745-W2-P15-G1-Lo-A-R Transformer Protection System has the A and the R options which indicate analog inputs and outputs and a restricted ground fault.

What testing capabilities does the GE Multilin 745-W2-P15-G1-Lo-A-R have?

The Multilin 745-W2-P15-G1-Lo-A-R has features that make it a great transformer protection system. It has simulation and testing features so that the operator can test the relay operation  by looking at either waveform data that is captured in the field or that is generated by a computer. This waveform data is then digitized and can be played back. Waveform data can also be recorded to look at fault, alarm, or inrush situations and conditions.
