This section offers a complete overview of the STBDDI3725KS basic digital input kit. It belongs to the Modicon STB distributed I/O solution family and serves as a ready-to-use package for collecting digital signals from field devices. Specifically, this kit includes three essential components: the STBDDI3725 module, the STBXBA3000 base, and the STBXTS1180 screw-type connector. Together, these parts simplify installation and reduce the time spent sourcing individual items.
First, let us examine the core input characteristics of the STBDDI3725KS. The kit provides sixteen digital input channels with a nominal voltage of 24V DC. The input voltage limits are clearly defined: a state 1 signal ranges from 11V to 30V, while a state 0 signal falls between -3V and 5V. Furthermore, the typical input current is 4.5mA, with guaranteed thresholds of >= 2.5mA for state 1 and <= 1.5mA for state 0. This positive logic configuration ensures compatibility with standard industrial sensors.
The response time of the Schneider STBDDI3725KS is consistent at 2ms for both off-to-on and on-to-off transitions. Consequently, this module is well-suited for applications that require reliable, real-time signal acquisition. Additionally, each input channel is protected by a resistor-limited circuit, while the integrated PDM fuse provides an additional layer of security against overcurrent events.
The STBDDI3725KS includes robust protection features to ensure system reliability. For instance, it offers reverse polarity protection to prevent damage from incorrect wiring. The insulation between channels and the logic bus is rated at 1500V for one minute, providing excellent electrical isolation. Moreover, the module supports both cold swapping and hot swapping when used with basic NIMs, allowing for maintenance without system shutdown. This capability significantly reduces downtime during troubleshooting or system expansion.
This input kit is engineered to perform in harsh industrial environments. The STBDDI3725KS operates across a wide temperature range of -25°C to 70°C without derating, making it suitable for demanding applications. Storage temperatures are even broader, spanning from -40°C to 85°C. Furthermore, the module offers an IP20 protection rating and complies with pollution degree 2 standards. Its vibration resistance reaches up to 5gn on a 35 x 15mm DIN rail, while shock resistance is rated at 30gn for 11ms, ensuring reliable operation in high-vibration settings.
The Schneider STBDDI3725KS arrives as a complete kit, which simplifies the procurement and installation process. The kit includes the STBDDI3725 digital input module, the STBXBA3000 base, and the STBXTS1180 18-terminal screw-type connector. This assembly approach ensures all components are perfectly matched for optimal performance. Installation is straightforward: mount the base onto a DIN rail, attach the module, and wire the connector to your field devices. The compact dimensions of 125mm width, 65.1mm depth, and 18.4mm height make this kit an ideal choice for space-constrained cabinets.
The STBDDI3725KS provides clear visual diagnostics to simplify system monitoring. A green LED labeled RDY indicates the module's operational status. Additionally, each of the 16 input channels features its own green LED, labeled IN1 through IN16, which illuminates when the corresponding input is active. This comprehensive status feedback allows technicians to quickly identify signal issues without requiring external diagnostic tools.
