FUNCTIONAL DESCRIPTION:
IS200JGPAG1A is a Ground and Power Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Turbine Control Systems. The PCAA core analog module and TCAT terminal board each provide twelve 4-20 mA inputs that are not provided with 24 V power for field devices. The Ground and Power (JGPA) board is a long narrow board that mounts adjacent to PCAA where shield wires are terminated. JGPA provides shield wire terminal points that may be tied directly to the underlying functional earth sheet metal or wired to a preferred grounding point. In this respect it is very similar to the JGND board offered as an option with other Mark VIe terminal boards. JGPA also provides twelve individually regulated and protected 24 V field device power outputs.
Each output is sufficient to power a single 4-20 mA field device. JGPA receives power from PCAA or TCAT through a 28 V power feed on connector Pl. Power passes through twelve regulators and is available on TB3 screws 1-12. TB3 uses terminals colored orange to set them apart from the terminals provided for shield wire termination. Shield terminals are on TB1 and TB2 using twenty-four conventional green euro-style box terminals for each.
INSTALLATION:
JGPA is installed adjacent to the terminals on PCAA and TCAT. Power is provided to JGPA through a cable from P1 to PCAA or TCAT. JGPA mounts on a sheet metal bracket that is at ground potential. When mounted with conductive hardware the ground path for JGPA shield wires is through the mounting bracket. If alternate shield wire grounding is desired the JGPA may be mounted with non-conductive washers and hardware. With isolated mounting, the ground is defined by one or more wires from JGPA shield ground terminals to the desired ground location.

What is the primary function of the board?
The Ground and Power Terminal Board is designed for use in GE’s Mark VIe Distributed Turbine Control Systems. Its main function is to provide shield wire terminal points and deliver regulated 24 V DC power outputs for field devices.
What are the mounting and grounding options for this board?
The board is mounted on a sheet metal bracket that is at ground potential. When mounted using conductive hardware, the shield wires are grounded through the mounting bracket. Alternatively, if isolated grounding is required, the board can be installed with non-conductive washers and hardware.
What types of terminals are used on the board?
The board features three types of terminal blocks. TB1 and TB2 include twenty-four green euro-style terminals designed for shield wire termination. TB3 is equipped with twelve orange-colored terminals dedicated to 24 V DC power outputs for field devices.
