- Input voltage: 24 V DC, limits: 15…30 V at state 1, -3…5 V at state 0
- Output voltage: 24 V DC
- Protection: integrated time lag fuse (10 A) on PDM, overload, short-circuit, resistor-limited input
- Hot swapping: supported for standard NIMs; cold swapping also available
- Fallback state: 0 for basic NIMs, user configurable for standard NIMs
- Electrical connection: 4 RJ45 connectors
- Current consumption: sensor bus ≤100 mA at 24 V DC; actuator bus ≤220 mA at 24 V DC for 150 ms; logic bus 100 mA at 5 V DC; actuator bus 50 mA at 24 V DC (all outputs off), 80 mA per output at state 1
- Dimensions: 170 mm depth, 28.1 mm height, 128.3 mm width; net weight 0.165 kg
Industry Applications
The Schneider STBEPI2145K is ideal for TeSys Quickfit and TeSys U motor control systems. It seamlessly integrates into distributed I/O architectures, providing a direct interface between sensors/actuators and the control network. Use it in assembly lines, packaging machinery, or any facility requiring modular I/O expansion with high reliability.
Installation & Setup Guidance
Mount the Schneider STBEPI2145K on a STBXBA3000 base using either spring clamp or screw type terminal connectors. Ensure the power distribution module (STBPDT3100/3105) supplies 24 V DC. The module supports both cold and hot swapping, allowing insertion without powering down the network when using standard NIMs. Connect via the 4 RJ45 ports for data communication.
Maintenance & Reliability
Designed for continuous operation from -25°C to 70°C, the Schneider STBEPI2145K withstands vibration up to 3 gn and shock up to 30 gn. The IP20 protection prevents debris ingress. Regular inspection of the fuse and connector integrity ensures long service life. The integrated overload and short-circuit protection minimizes unplanned downtime.
Selection Guide & Purchasing Advice
Before purchasing, verify compatibility with your power distribution module (STBPDT3100/3105) and mounting base (STBXBA3000). The STBEPI2145K replaces older interface modules and upgrades system performance. For genuine Schneider automation parts, trust UBEST Automation as your reliable supplier.
