I/O modules

This IS200SFCBG1A IS200SFCBG1AAA board generates firing pulses for thyristors. It serves critical roles in excitation and drive systems. The enhanced IS200SFCBG1A IS200SFCBG1AAA version includes a factory-applied conformal coating.

Technical Specifications

The IS200SFCBG1A IS200SFCBG1AAA measures 190 mm in length. Its width reaches 140 mm with a height of 30 mm. This firing board weighs approximately 0.85 kilograms. A single multilayer PCB holds all pulse generation circuitry.

Design and Energy Storage

This IS200SFCBG1A IS200SFCBG1AAA stores minimal energy in small capacitors. Each channel uses a dedicated pulse transformer for isolation. Switching transistors deliver fast rise times under 500 nanoseconds. Surface-mount technology boosts reliability in industrial environments. Moreover, the coated IS200SFCBG1A IS200SFCBG1AAA resists moisture and dust effectively.

Installation and Connectivity

You can mount this board directly into the Mark VIe rack. It receives firing commands via fiber optic cables. Six output terminals connect directly to thyristor gate drivers. Consequently, you complete the installation within a few minutes. Finally, keyed connectors prevent any incorrect cable insertion.

Performance and Timing Accuracy

This consumes only 8 watts during operation. Its pulse timing accuracy reaches ±0.1 degrees at 60 Hz. Thus, you get precise control for SCR firing applications. Each output withstands continuous short-circuit conditions safely. The board also features built-in pulse transformer protection diodes.

Typical Applications

Use this for generator excitation control systems. It also excels at motor drive thyristor firing tasks. Many plants select it for static starter systems. The compact board design saves valuable rack space effectively. Finally, LED indicators show pulse activity for each channel.
