About the IS420PUAAH1A
The IS420PUAAH1A is a Universal Input/Output Module from General Electric. It is designed for use within distributed control systems and BOP (balance of power) control systems. Typically, it is used within the Mark VIe control system and is similar to the YUAA board used within a Mark VIeS system. These systems were the most advanced and latest released Speedtronic systems from GE for the management of gas and steam turbine systems.
The IS420PUAAH1A is designed for use with ControlST version 7.02.00C or later.
The IS420PUAAH1A allows users to use fewer panels and have a smaller footprint for their system by offering black sections that can be independently wired, which allows for channel-by-channel commissioning. The module has sixteen Simplex analog channels. These can be configured individually as the following:
-
Thermocouple I/O
-
RTD I/O
-
Voltage Input
-
4-20 mA current input
-
0-20 mA current output
-
Pulse accumulator
-
Digital input
The IS420PUAAH1A supports a frame rate of 10ms. Auto-reconfiguration is supported. The unit is hot-swapped replacement supported. It is designed to operate in temperatures ranging from -40 to 158 degrees Fahrenheit in 5% to 95% relative humidity, non-condensing. Normal scan time is 5 ms and measurement accuracy is better than 0.1% within the specified temperature range.
For additional information about the IS420PUAAH1A, please refer to user guides and manuals originally published by General Electric. These publications will have detailed, important information regarding the handling and installation of this equipment.
