FUNCTIONAL DESCRIPTION:
IS200JPDCG1AFC is a Power Junction Distribution Module manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. This Power Junction Distribution Module plays a vital role in the management and distribution of various power supplies within the system. It efficiently handles and distributes 125 V DC, 115/230 V AC, and 28 V DC to different boards and components, ensuring that each part of the control system receives the necessary power. This module is built to withstand the demanding conditions of industrial environments, making it a dependable choice for maintaining the stability and efficiency of turbine operations.
INSTALLATION:
The JPDC module is typically mounted vertically with the 115/230 V ac input connector (JAC) at the bottom. It is attached with four screws using the mounting holes located at the top and bottom of the module base. Location within the control cabinet is not critical, however, distribution boards are usually mounted low in the cabinet to facilitate grounding. Refer to the section, Grounding. The optional PPDA I/O pack is plugged into connector JA1. It is secured to the JPDC base using an angle bracket, held in place with nuts threaded onto studs, that are permanently attached to the base for that purpose. Diagnostic feedback inputs from other distribution boards are routed to JPDC through a 50-pin ribbon cable attached to connector P2. Input power connections include:
OPERATION:
AC POWER DISTRIBUTION:
An input of either 115 Vac or 230 V ac is supplied to JPDC through connector JAC. The maximum allowable current is 12.5 amps rms. It is expected that the low or neutral side of the input power is grounded. (Refer to the functional diagram) Two ac outputs are provided. Both are protected by a 10 A time-delay fuse on the high side only (Pin 1 of each connector). The output at JAC1 is controlled by the toggle switch SWAC1. The JAC2 output is not switched.
125 V DC POWER DISTRIBUTION:
JPDC can accept two battery inputs through connectors JD1 and JD2. Provision is also made for a third 125 V dc input from an ac/dc converter such as IS2020DACA through connector JZ2. Each input is typically routed through an external filter. Input voltage range 90 – 145 V dc. The two battery inputs are OR’ed together by diode module D1 and are OR’ed with 125 V dc from DACA by a diode on the DACA module. The OR’ed 125 V dc inputs combine on JPDC to form a 125 V dc bus labeled PDC. The return paths of the 125 V dc inputs are connected and labeled NDC. Total 125 V DC flow should not exceed 20 amps. All three 125 V dc inputs are floating concerning ground. When jumper JP2 is installed, each side of the 125 V dc bus is connected to FE ground through approximately 84 k ohms of resistance to provide a means of ground fault detection.

What types of power do these modules typically distribute?
Power Junction Distribution Modules can distribute various types of power, including DC (Direct Current) and AC (Alternating Current) voltages. Common voltages include 125 V DC, 115/230 V AC, and 28 V DC, depending on the specific requirements of the control system and its components.
Why are Power Junction Distribution Modules important in control systems?
These modules are crucial for ensuring that different parts of a control system receive the correct power supply. They help to manage power distribution efficiently, prevent overloads, and maintain the stability and reliability of the control system.
How do Power Junction Distribution Modules integrate with other system components?
Power Junction Distribution Modules are designed to be compatible with other components in a control system. They often combine various input and output functions into a single module, simplifying power management and ensuring seamless integration with the overall system architecture.
