IS220PAOCH1A is an Analog Output Module manufactured by General Electric as part of Mark VIe used in gas turbine control management systems. An electrical interface between one or two I/O Ethernet networks and an analog output terminal board is provided by the Analog Output (PAOC). A BPPx processor board and an acquisition board pair tailored to the analog output function are both present in the PAOC. Up to eight simplexes, 0-20 mA current loop outputs can be provided by the PAOC, which also has an analog to digital converter for each output's current feedback. Dual RJ-45 Ethernet connectors and a three-pin power input serve as the PAOC's inputs. The related terminal board connector is directly connected to the output via a DC-37 pin connector. Indicator LEDs are used to display visual diagnostics.
One of the following BPPx processor boards is compatible with the PAOC I/O pack:
ANALOG OUTPUT HARDWARE:
Eight simplex 0-20 mA analog outputs with 18 V compliance are included in the PAOC. An external transistor amplifier is controlled and driven by a 16-bit digital-to-analog converter (DAC), which also controls the output current. To alert the control if the internal temperature of the pack becomes too high, a temperature sensor is built inside the board. Additionally, each analog output circuit has a mechanical normally-open relay that controls whether the output is enabled or disabled. When the disabled relay is turned off, the output flows via the relay and opens a circuit between the customer load attached to the terminal board and the analog output of the PAOC. The location of the mechanical relay is signaled by an LED using the second normally-open contact of the relay.
CURRENT FEEDBACK HARDWARE:
The PAOC I/O pack, which has eight linear, high-compliance analog outputs, has application restrictions based on its probable ambient environment. As measured from the outside of the pack, PAOCH1B packs are designed to operate within a temperature range of -40 to 70 oC (-40 to 158 oF). Due to its dense triple board layout and depending on the application, the PAOC's ambient environment maximum must be reduced. Here is a list of output configurations along with the necessary de-ratings for each one. As evidenced by the terminal board screws across the output range of 0–20 mA, the minimum series equivalent resistance of the customer load is the definition of the minimum output impedance.
The PAOC I/O pack performs the following self-diagnostic tests:
A power-up self-test that examines the hardware on the processor board, Ethernet ports, RAM, and flash memory.
The analog output suicide relay's compliance with the commanded condition and feedback indication is continuously checked.
