GE IS200RAPAG1B IS200RAPAG1BAA Contact Input Terminal Board

The IS200RAPAG1B IS200RAPAG1BAA functions as a contact input terminal board for turbines. This printed circuit board belongs to the Mark VI Speedtronic series from General Electric. The IS200RAPAG1B serves as the standard version for dry contact monitoring. Its variant, the IS200RAPAG1BAA, includes a conformal coating for extra circuit protection. Both boards process contact input signals for steam and gas turbine controls.

Core Technical Specifications

This board provides sixteen dry contact input channels for field devices. You will also find built-in opto-isolation for each input channel. The board stores minimal energy but uses capacitors for contact debouncing. Meanwhile, the backplane interface handles all power and data transfers.

Installation and System Integration

Install the IS200RAPAG1B IS200RAPAG1BAA into any standard VME rack slot. The board connects directly to dry contacts through its screw terminals. Meanwhile, the backplane supplies power and communication to the board. Therefore, proper insertion ensures reliable contact input monitoring.
