Multi-Function I/O Processing Features

The GE DS200ADG1H1A DS200ADG1H1AAA Multi I/O PC Board handles diverse field signals efficiently. A 14-bit ADC converts all analog inputs with 0.05% accuracy. The board provides loop power for 4-20mA two-wire transmitters directly. Furthermore, the relay outputs can switch AC or DC loads up to 2A. Consequently, this single board replaces multiple dedicated I/O cards.

Installation and Connection Steps

Mount this GE DS200ADG1H1A DS200ADG1H1AAA Multi I/O PC Board in any Mark V rack slot. First, connect field wiring to the TB1 terminal block carefully. After that, attach the ribbon cables to the main controller via the three headers. Then, set the channel configuration jumpers for your specific sensor types. Finally, verify each input and output using a known signal source.

Energy Discharge and Safety Notice

This GE DS200ADG1H1A DS200ADG1H1AAA Multi I/O PC Board stores minimal energy in its capacitors. However, you must wait 30 seconds after power removal before handling. The twelve signal capacitors discharge through protection circuits during this time. Never apply voltages above the specified input range to any channel.

Status Indication and Diagnostics

A green LED indicates the board has power and communicates properly. A yellow LED flashes during active analog-to-digital conversion cycles. A red LED illuminates when any input exceeds the safe operating range. Eight individual LEDs show the status of each relay output clearly.
