Energy Storage and Signal Filtering Performance
The GE IS200SSCAH2A IS200SSCAH2AEC stores sufficient energy for stable signal conditioning. Its nine capacitors provide 900 µF of total capacitance. This storage filters high-frequency noise from field wiring. Furthermore, the suppression diodes clamp voltage spikes at 30 VDC, protecting the main rack electronics.
Role Within the Mark VI Speedtronic System
You will typically find the GE IS200SSCAH2A IS200SSCAH2AEC mounted near the I/O rack termination panel. It connects to the main rack via two shielded ribbon cables. Moreover, this board supports a mix of analog and digital signal types. Its eighteen terminal blocks accept wiring from sensors, actuators, switches, and transmitters.
Installation and Wiring Guidelines
Use the GE IS200SSCAH2A IS200SSCAH2AEC as a direct replacement for older SSCA revisions. Always disconnect field power before terminating any wires. This terminal board requires no external power supply for passive signal paths. It needs no configuration jumpers or special tools. Simply secure the board with four mounting screws and connect your field cables to the appropriate terminal blocks.
