The IS220PAICH1B, REV B is an Analog Input/Output (PAIC) Pack designed and manufactured by General Electric for the Distributed Mark VIe turbine control systems. The Analog I/O pack (PAIC) provides the electrical interface between one or two I/O Ethernet networks and an analog input terminal board. The PAICH1B, REV B contains a BPPX processor board and an acquisition board specific to the analog input function. The I/O pack is capable of handling up to 10 analog inputs, the first eight of which can be configured as +5 V or ±10 V inputs, or 4-20 mA current loop inputs. The last two inputs may be configured as ±1 mA or 4-20 mA current inputs. The load terminal resistors for current loop inputs are located on the terminal board, and voltage is sensed across these resistors by the PAIC. The PAICHI also includes support for two 0-20 mA current loop outputs. The PAICH2 includes extra hardware to support 0-200 mA current on the first output. Input to the I/O pack is through dual RJ-45 Ethernet connectors and a three-pin power input. Output is through a DC-37 pin connector that connects directly with the associated terminal board connector. Visual diagnostics are provided through indicator LEDs.
COMPATIBILITY:
The PAICH1B, REV B I/O pack includes one of the following compatible BPPx processor boards. The PAICHIA and H2A contain a BPPB processor board. The PAICHIB and H2B contain a functionally compatible BPPC that is supported in the ControlST* software suite V04.03 and later. PAICH2A and H2B also include extra hardware to support 0-200 mA current on the first output. The PAIC is compatible with the analog input terminal board (TBAIHIC) and the STAI board, but not the DIN rail-mounted DTAI board. The PAIC is only compatible with the HIC version of TBAI and will report a board compatibility problem with any of the earlier revisions. No physical damage will result if a PAIC is powered up on an older board in error.
INSTALLATION:
ANALOG INPUT HARDWARE:
Inputs 1-8 can be individually configured as ±5 V, ±10 V, or 4-20 mA scale signals, depending on the input configuration. Inputs 9-10 can only be configured for +1 mA or 4-20 mA. The terminal board provides a 250 2 burden resistor when configured for current inputs, yielding a 5 V signal at 20 mA. These analog input signals are first passed through a passive, low-pass filter network with a pole at 75.15 Hz. Voltage signal feedback from the analog output circuits and calibration voltages are also sensed by the PAIC analog input section.
ANALOG OUTPUT HARDWARE:
The PAIC includes two 0-20 mA analog outputs capable of 18 V compliance, running simplex or TMR. A 14-bit DAC commands a current reference to the current regulator loop in the PAIC that senses current both in the PAIC pack and on the terminal board. In TMR mode, the three current regulators in each PAIC share the commanded current loads among themselves. Analog output status feedback for each output includes.
