Powering the PACSystems RX3i: The IC695PSD140
The IC695PSD140 is a power supply module from the PACSystems RX3i series, manufactured by Emerson Automation (formerly GE Intelligent Platforms). This DC power supply is designed to deliver reliable power to RX3i systems, supporting both load-sharing and redundancy configurations. Its robust design makes it a suitable choice for demanding industrial environments.
With an input voltage range of 18 to 30 VDC and a maximum input power of 60 Watts at full load, the IC695PSD140 provides a stable power foundation. It offers three outputs: 5.1 VDC, 3.3 VDC, and 24 VDC, each with specific current ratings. This flexibility allows it to power various RX3i modules and relay circuits.
Key Technical Specifications
Understanding the technical parameters of the IC695PSD140 is essential for proper system design. The module operates with an input voltage range of 18 to 30 VDC, ensuring compatibility with standard DC power sources. Its maximum input power is 60 Watts at full load, and the total output power is 40 Watts.
The output specifications are as follows:
- 24 VDC output: 0 to 1.6 Amps (for power circuits and output relay modules)
- 5.1 VDC output: 0 to 6 Amps (nominal 5.1 VDC)
- 3.3 VDC output: 0 to 9 Amps (nominal 3.3 VDC)
Each output has a defined voltage range: 24 VDC from 19.2 to 28.8 VDC, 5.1 VDC from 5.0 to 5.2 VDC, and 3.3 VDC from 3.1 to 3.5 VDC. The module also features a ripple and noise specification of 150 mV, ensuring clean power delivery.
Redundancy and Load Sharing
The IC695PSD140 supports redundancy and load-sharing applications, making it a versatile choice for critical systems. Up to four PSD140 modules can be installed in an RX3i universal backplane, allowing for increased capacity and fault tolerance. In a load-sharing configuration, all power supplies must be connected to the same power source, and the On/Off switch on the front panel should not be turned off inadvertently.
This capability is particularly valuable in industries where downtime is not an option, such as process control or data acquisition. By distributing the load across multiple supplies, the system can continue operating even if one module fails.
Installation and Compatibility
The IC695PSD140 is designed for installation in an RX3i universal backplane, occupying two slots. It is compatible with any RX3i Central Processing Unit (CPU). The module does not have jumper or DIP switches, simplifying setup. Recommended wire size for terminal connections is #14-22 AWG, with a maximum terminal current of 6 Amps.
It is important to note that the IC695PSD140 cannot be used in redundant or increased capacity modes with the IC695PSD040 or IC695PSA040 power supplies. Attempting to do so may cause damage to the equipment.
LED Indicators and Diagnostics
The module includes four LED indicators that provide real-time status: Power, P/S Fault, Overtemperature, and Overload. These indicators help operators quickly identify operational issues. The Power LED can be green or amber, while the P/S Fault and Overload LEDs are red, and the Overtemperature LED is amber.
These diagnostics are crucial for maintaining system health and minimizing downtime. By monitoring these LEDs, maintenance teams can proactively address potential problems before they escalate.
