Key Technical Specifications

This GE IS200TVBAS2A IS200TVBAS2AAA board accepts 24V DC loop-powered sensor inputs. It converts 4-20mA vibration signals from proximity probes and accelerometers. The unit measures 17 cm in length, 12 cm in width, and 3.5 cm in height. Its total weight equals 0.45 kg without any packaging.

The GE IS200TVBAS2A IS200TVBAS2AAA includes eight analog input channels for vibration monitoring. Additionally, it features one 25-pin D-sub connector for host system interface. A two-part terminal block simplifies field wiring connections. The board contains 8 signal conditioners, 2 multiplexers, 6 op-amps, and 24 resistors.

GE IS200TVBAS2A IS200TVBAS2AAA stores energy using one electrolytic capacitor. This capacitor provides 100 µF at 35V rating for transient filtering. Consequently, the board rejects high-frequency noise above 1 kHz from vibration signals.

Design and Integration

Both the GE IS200TVBAS2A and GE IS200TVBAS2AAA versions share identical signal conditioning. These boards use four-layer PCB construction with analog and digital ground separation. Therefore, the GE IS200TVBAS2A IS200TVBAS2AAA operates reliably from -10°C to +55°C ambient temperature.

For installation, you need M3 screws for the four mounting holes. The board draws 150 mA typical current from the 24V DC supply. Each input channel provides 24V loop power to the connected sensor. We recommend using shielded twisted-pair cables for field wiring.

Practical Application

This terminal board connects eddy current probes and accelerometers to vibration monitors. It converts each 4-20mA signal into a digital value for the main controller. The GE IS200TVBAS2A IS200TVBAS2AAA also includes over-range detection for sensor faults. Therefore, it enables predictive maintenance of turbines, compressors, and pumps.
