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 GE Multilin 745-W2-P15-G1-Lo-A-R Transformer Protection System can monitor and respond to physical and electronic variables like temperature, harmonics, and overexcitation. The system extends system life through its protective capabilities and efficient management of transformer systems.

Product Description

The 745-W2-P15-G1-LO-A-R is a transformer management relay produced by GE Multilin and protects transformer systems by monitoring and responding to physical and electronic variables, such as harmonics, overexcitation, temperature, and currents.The 745 is able to adapt to shifting conditions within the transformer system, taking necessary steps to alleviate strain. It is able to protect and manage transformer systems small, medium, and large. Users can establish setpoints (analogous to settings) that help determine how the relay manages and protects the system. Setpoints can be easily saved and loaded from file using a computer running EnerVista 745 connected to the device’s RS232 port.

The body of the device itself is divided up into approximately four sections, which includes the display, status indicators, keypad, and RS232 interface. The display is a forty character LCD which is capable of displaying screens needed to assign and edit setpoints. The liquid crystal display also can indicate errors as they emerge, especially in response to incorrect keypad entry. The liquid crystal display can also passively read off different system values when not in active use, and users can edit the relay’s settings to shift what appears during the idle process. In addition to the LCD, a number of LEDs located at the front of the case provide insight into system functionality, indicating if issues such as self-test errors or transformer overloads occur. The keypad can be used to manually adjust setpoints, and the RS232 port can connect computers running the EnerVista 745 software to the 745 relay itself, which allows for quicker and easier programmability.
