The STBPDT3100K from Schneider Electric provides a standard power distribution solution for Modicon STB distributed I/O networks. You can use this kit to supply both sensor and actuator buses. Therefore, system power management becomes more organized and reliable.
This kit delivers 10A at 45°C for input/output circuits. For higher temperatures, the output current adjusts automatically. Additionally, the kit includes built-in overcurrent protection with time-lag fuses.
The STBPDT3100K contains five key components. First, you get the STBXTS2130 spring type connectors. Second, the STBPDT2100 power module handles the main distribution. Third, the STBXBA2200 mounting base provides physical support. Fourth, STBXTS1130 screw type connectors offer an alternative wiring method. Finally, all necessary hardware is included for immediate installation.
Electrical ratings are robust for industrial use. The rated supply voltage is 24V DC with an operating range of 19.2 to 30V DC for the sensor and actuator bus.
Input circuit current ranges from 0 to 4A at 30°C. The output circuit at the same temperature handles 0 to 8A.
Protection features include built-in overcurrent protection. A 10A time-lag fuse guards the output circuit. A separate 5A time-lag fuse protects the input circuit. Additionally, reverse polarity protection is provided for the actuator bus.
Voltage detection works with a threshold of 15V. When voltage falls below 15V, the DC IN/OUT LED lights up. Above 15V, the LED remains off.
Dimensions are compact. Width measures only 18.4mm, height is 125mm, and depth is 65.1mm. This slim profile saves valuable DIN rail space.
Net weight is just 0.13kg. When packaged, gross weight reaches 0.28kg.
Hot swapping is not supported. The STBPDT3100K detects illegal hot swap events. Always power down the system before inserting or removing this module.
Temperature range for operation is 0 to 60°C without derating. With derating factors applied, operation extends from -25 to 70°C. Storage temperature spans -40 to 85°C.
Humidity tolerance reaches 95% at 60°C without condensation. Therefore, the kit works well in humid factory environments.
Vibration resistance depends on the DIN rail used. On a 35×7.5mm symmetrical rail, tolerance is ±0.35mm at 10-58Hz and 3gn at 58-150Hz. On a 35×15mm rail, tolerance increases to 5gn at 58-150Hz.
Shock resistance is rated at 30gn for 11ms, conforming to IEC 88 reference 2-27.
Pollution degree is 2 according to IEC 60664-1. The IP20 protection rating meets EN 61131-2 class 1 standards.
Operating altitude is limited to 2000m maximum.
The STBPDT3100K holds multiple certifications. These include UL, CSA, FM Class 1 Division 2, and CE marking. Overvoltage category is II.
Two green LEDs provide status information. One LED indicates actuator bus power supply (OUT). The other LED shows sensor bus power supply (IN). A quick glance tells you whether both buses are powered correctly.
First, mount the STBXBA2200 base onto a standard DIN rail. Next, attach the STBPDT2100 power module to the base. Then connect your sensor wires using either spring type (STBXTS2130) or screw type (STBXTS1130) connectors.
For the actuator bus, repeat the same wiring process. Meanwhile, ensure the system is completely powered off. The STBPDT3100K does not support hot swapping, so never install or remove it with power applied.
Finally, verify all connections are secure. Turn on the 24V DC supply and check both green LEDs illuminate.

1. Can I hot swap the STBPDT3100K?
No. The STBPDT3100K specifically marks hot swapping as illegal. You must power down the entire Modicon STB system before installing or removing this kit.
2. What is the maximum output current at 60°C?
At 60°C, the STBPDT3100K delivers 8A for the I/O circuit. At 70°C, output drops to 6A. For full 12A output, keep the ambient temperature at or below 30°C.
3. Which mounting base does this kit require?
The STBPDT3100K includes the STBXBA2200 base. You do not need to purchase a separate base. This base is specifically designed for compatibility with the STBPDT2100 module.
4. How do I know if the sensor bus is powered?
Look at the green LED marked IN on the STBPDT3100K. When illuminated, the sensor bus has proper voltage above 15V. When off or dim, voltage has dropped below the 15V threshold.
5. What types of connectors are included?
The STBPDT3100K includes both spring type (STBXTS2130) and screw type (STBXTS1130) connectors. You can choose either wiring method based on your preference or maintenance requirements.
