Functional Description

IS210DPWAG1A is a Transducer Power Distribution Terminal Board developed by GE. It is part of the Mark VI series. The terminal board is designed for DIN-rail mounting, ensuring secure installation within the system setup. It accepts input voltage of 28 V dc 5 percent, provided through a two-pin Mate-N-Lok connector. Connectors are available for two independent power sources, allowing for the utilization of redundant supplies to enhance system reliability.

Features

• Input Voltage Compatibility: The input can accept power from a floating isolated voltage source, offering flexibility in power source selection.
• Power Attenuation and Monitoring: Two 1 kohm resistors from positive and negative input power to SCOM center a floating power source on SCOM.
  Attenuated input voltage is provided for external monitoring, enabling efficient system diagnostics and management.
• Output Power Distribution: Output power of 12 V dc (5 percent) is distributed to external devices through a Euro-type terminal block, utilizing screw terminals and AWG#18 twisted-pair wiring. Provides three output terminal pairs, offering a total output rated at 0 to 1.2 A, ensuring compatibility with a variety of external devices and components.
• Compatibility and Protection: The outputs are compatible with the XDSAG#AC interface board, facilitating seamless integration with other system components. Outputs are equipped with short-circuit protection mechanisms, ensuring safety and preventing damage to connected devices. Additionally, they are self-recovering, enhancing system resilience and longevity.

Installation Procedure

• Mounting: Securely mount the DPWA assembly on a standard DIN-rail within the designated location in your system setup. Ensure the DIN-rail is suitable for supporting the weight and size of the DPWA assembly.
• Connecting Input Power: Identify connector P1 on the DPWA terminal board designated for input power connection. Connect the input power source, which typically provides a voltage of 28 V dc (5 percent), to connector P1. Ensure proper polarity and secure connections to prevent any loose wiring.
• Utilizing Multiple Boards: If you are using multiple DPWA boards in your setup for redundancy or expanded power distribution-
  • Use connector P2 as a pass-through connection point for the power to additional DPWA boards. This ensures seamless power distribution across multiple boards.
  • If a redundant power input is provided, Connect the redundant power source to connector P3 on the DPWA terminal board. Use connector P4 as the pass-through connection point to distribute power to additional DPWA boards in the system.
• Final Checks: Before powering up the system, double-check all connections to ensure they are secure and properly aligned. Verify that input power sources are within the specified voltage range and polarity requirements to avoid any potential damage to the DPWA terminal board or connected devices.

Frequently Asked Questions

What is IS210DPWAG1A?
It is a transducer power distribution terminal board developed by GE under the Mark VI series.

What are the voltage monitor outputs provided by the terminal board?
Features three voltage monitor outputs for monitoring board input power- PSRet, PS28VA, and PS28VB.

How are the voltage monitor outputs attenuated, and what is the purpose of attenuation?
The voltage monitor outputs are attenuated by a 6, 1 ratio, allowing for the reading of the 28 V dc input voltage using a 5 V dc full-scale input. Attenuation ensures that the voltage levels are compatible with monitoring equipment and prevent damage to sensitive components.

What are the specific functions of terminals PSRet, PS28VA, and PS28VB?
Terminal 1 (PSRet) Attenuated voltage present on the power input return line. Terminal 3 (PS28VA) Attenuated voltage present on the P1 positive power input line. Terminal 5 (PS28VB) Attenuated voltage present on the P3 positive power input line.

How do redundant systems utilize the voltage monitor outputs for monitoring?
In redundant systems, monitoring PS28VA and PS28VB enables the detection of a failed or missing redundant input, ensuring system reliability and fault tolerance.
