Functionality
The FC-TPSU-2430 is a DC/DC converter module that provides an isolated 30 V DC / 1 A output. It powers field termination assemblies (FTAs) such as the TSAI-1620m and TSHART-1620m. The module includes voltage monitoring features with local LED indications and alarm functions, triggered by a read-back relay contact, ensuring real-time feedback on output status.
Key Features
- Voltage Monitoring
- Local LED indicates output voltage status.
- Read-back relay contact closes when output voltage is within the acceptable range.
- Galvanic Isolation
- Isolates input, output, and relay contact connections to enhance safety and system integrity.
- Robust Design
- Short-circuit proof output with overvoltage protection.
- High efficiency (>75%) with natural convection cooling.
- Safety Compliance
- Certified for SIL3 applications.
- Meets various safety standards: CE, TUV, UL, CSA, and FM.
- Mounting Options
- Compatible with DIN rail mounting (TS32/TS35).
- Can be installed horizontally or vertically.
Connections
Input Terminals
| Terminal | Function |
|---|---|
| 1 | Read-back contact |
| 2 | Read-back contact |
| 3 | 24 V DC IN (+) |
| 4 | 24 V DC IN (–) |
Output Terminals
| Terminal | Function |
|---|---|
