I/O Processing and Isolation Features

The GE DS200SIOCG1A DS200SIOCG1ADA VME Stand I/O Board optically isolates all field inputs from the logic side. Each input channel includes a programmable debounce filter for noise rejection. The output channels feature short circuit protection with automatic shutdown. Furthermore, the board maps all I/O directly into VME memory space. Consequently, the main processor can access status without complex communication protocols.

Installation and Connection Steps

Mount this GE DS200SIOCG1A DS200SIOCG1ADA VME Stand I/O Board into any standard 6U VME rack slot. First, connect field wiring to the two 50-pin ribbon headers. After that, seat the board firmly into the P1 and P2 backplane connectors. Then, secure the board using the front panel ejector handles. Finally, configure the base address using the onboard DIP switches before powering up.

Energy Discharge and Safety Notice

This GE DS200SIOCG1A DS200SIOCG1ADA VME Stand I/O Board stores minimal energy in its capacitors. However, you must wait 30 seconds after power removal before handling. The eight decoupling capacitors discharge through internal resistors. Never connect voltages above 30V DC to any input or output channel.

Status Indication and Diagnostics

A green LED indicates the board has VME power and bus access. A yellow LED flashes during active input scanning cycles. A red LED illuminates when any output channel detects an overload condition. These indicators help technicians verify board operation without software tools.
