General Electric developed the 193X277ACG01 card as a signal level detector. This card was developed for the 193X series of GE brand replacement boards. A number of drives and exciters across the series can accept this card in its cabinet. Installing this card provides the drive with relay operation. The G01 version of the card provides one relay channel to the board.
Installing this board provides the drive with an additional relay position. The 193X277ACG01 board features integrated indicator lights connected to the relay. Should any input voltage level fed to the board raise above any preset voltage level, the indicator light will visually alert the user. Inputted voltages levels sourced to the board can range from 0.1 V to 10 V. An onboard potentiometer is used to adjust that level to acceptable voltages for the board. The pick-up level of the card can also be adjusted with a potentiometer. Relay interlocks on the board include a holding current of 0.3 A and a 1.5 A inrush at a voltage of 115 VAC.
Any provided installation and storage parameters should be reviewed before installing the board. Users should aim to follow all of these guidelines as they reduce the risk of damages to the device. Only users who are qualified to handle GE drive boards should be permitted to install the 193X277ACG01 signal level detector card. Wiring diagrams are available in the manual and datasheet associated with this device. The manufacturer, General Electric, originally provided technical support for this card.
