Key Features and Engineering Advantages

• Programmable Transducer Voltage: Offers the flexibility to power different generations of sensors by selecting between -24 Vdc (modern 3300 XL series) or -18 Vdc (legacy transducers).

• System Integrity Monitoring: The normally energized OK Relay ensures that if the power module fails or loses input, the relay de-energizes, providing a fail-safe signal to the plant’s DCS or SCADA system.

• Wide Input Range: Designed to handle significant fluctuations in DC input voltage, ensuring the rack remains operational during electrical transients or battery backup transitions.

• API 670 Compliant: Meets the stringent requirements of the American Petroleum Institute for machinery protection systems, guaranteeing the highest level of safety and reliability for critical rotating assets.

• Optimized Heat Dissipation: The rugged mechanical design and high-efficiency components allow the module to operate at full load in ambient temperatures up to +65°C without the need for external cooling.
