GE IS200STAOH2A Simplex Analog Output Terminal Board

GE IS200STAOH2A Simplex Analog Output Terminal Board

Functional Description

The Simplex Analog Output (STAO) terminal board is a compact analog output terminal board, designed for

DIN-rail or flat mounting. STAO has eight 0-20 mA analog outputs driven by the PAOC I/O pack. The on-

board circuits and noise suppression are the same as those on TBAO terminal board. High-density Euro-

block type terminal blocks are mounted on the board for wiring to the customer's devices. An on-board ID

chip identifies the board to the I/O processor for system diagnostic purposes. The I/O pack plugs into the D-

type connector and communicates with the controller over Ethernet.

Operation

STAO supports eight analog control current outputs. On each output, the voltage drop across the local loop

current sense resistor is measured and the signal is fed back to the I/O processor that controls the current.

Filters reduce high-frequency noise and suppress surge on each output near the point of signal exit. The I/O

processor contains the D/A converter and drivers that generate the controlled currents.
