TPSU-2430 DC/DC Converter Module

Overview: The TPSU-2430 is a high-efficiency DC/DC converter designed to deliver an isolated 30V DC / 1A output to field termination assemblies (FTAs) such as the TSAI-1620m and TSHART-1620m. This module includes voltage monitoring with LED indication and alarm functions via a read-back relay contact, ensuring reliable and safe operation.

Features:

• Isolated Output: Provides a stable 30V DC / 1A output.
• Voltage Monitoring: LED indication for real-time voltage status.
• Alarm Functions: Equipped with overvoltage protection and undervoltage detection.
• Safety Compliance: Meets SIL3 safety class requirements.
• Flexible Mounting: Suitable for horizontal or vertical installation on DIN rails.
