Product Description

The General Electric 531X305NTBAJG1 card was developed to function as an NTB/3TB terminal board. This card was manufactured with the 531X series of replacement drive and exciter boards. A number of critical device features are provided when this board is installed. Some of the interfacing capabilities of the card include relay and serial outputs, power supplies, encoders, and analog I/O.

A number of important features are provided to the host drive from the NTB/3TB terminal board. When installed, the 531X305NTBAJG1 card can produce regulated output supplies rated at 5 VDC and 15 VDC. Unregulated supplies of 24 VDC and 120 VAC are also produced by the board. Jumpers on the card also allow for interfacing configuration for 5 V and 15 V encoders. Within the board are seven relays that are either form C or form A output types. Each relay features a contact fating of 120 VAC. Four potentiometers are also found on the board. These allow for low level analog I/O scaling to occur.

Users are urged to review all installation parameters provided by the manufacturer before beginning board installation. Following these guidelines will help to prevent any accidental damages to the device. To ensure proper board use, only allow qualified personnel to handle and install the 531X305NTBAJG1 NTB/3TB terminal board.
