MeloAuto-Trusted PLC & DCS Parts Supplier
The GE DS200CSSAG1A DS200CSSAG1AAA cell state sensor board monitors digital status signals for GE Mark V systems. This board reads contact closures from relays, switches, and circuit breakers. You will find this sensor board in turbine control cabinets and switchgear panels. Its high-density design packs sixteen inputs into a single slot.
Input Architecture and Signal Detection
This sensor board provides sixteen digital input channels for status monitoring. Consequently, it can track multiple field devices from one board. The GE DS200CSSAG1A DS200CSSAG1AAA accepts both dry contacts and voltage-driven signals. Moreover, each channel includes individual LED status indicators. You can quickly identify active inputs without external tools.

Channel Monitoring and Status Indication
The unit includes sixteen optocouplers for complete electrical isolation. Therefore, field wiring faults cannot damage the main controller. This board replaces the DS200CSSAG1AAA version without any configuration changes. Simply remove the old board and install this one. GE designed this sensor board for single-slot installation. Hence, it fits directly into existing Mark V rack positions.
Four PCB layers separate field input traces from logic circuits effectively. Three connectors handle all field, backplane, and status signals. The GE DS200CSSAG1A DS200CSSAG1AAA includes software-selectable debounce filtering on each channel. Accordingly, it rejects contact bounce from mechanical switches. This feature ensures stable readings in noisy industrial environments.
Input Configuration and Installation Guide
You can configure each channel for dry contact or voltage input modes. Jumper settings on the board select the input type per channel. The GE DS200CSSAG1A DS200CSSAG1AAA works with limit switches, push buttons, and relay contacts. Always use shielded cable for input wiring longer than 30 meters. Sixteen LEDs provide immediate visual feedback for every channel.
The board supplies 2 mA wetting current for dry contact cleaning. This current prevents oxide buildup on unused relay contacts. The GE DS200CSSAG1A DS200CSSAG1AAA works with all GE Mark V control systems. Proper grounding of the common reference prevents false triggering. This board operates reliably in non-condensing environments only.
