Product Introduction
The Schneider STBDDI3615K Basic Digital Input Kit provides six reliable 24 V DC discrete inputs for Modicon STB distributed I/O solutions. This kit includes the STBDDI3615 module, STBXBA1000 base, and two connectors: a screw-type and a spring clamp. Designed for industrial automation, the Schneider STBDDI3615K ensures stable signal acquisition even in noisy environments.
Technical Specifications Breakdown
The Schneider STBDDI3615K operates with a 24 V DC supply and draws 45 mA from the 5 V DC logic bus. Key performance specs include:
-
Input voltage limits: 15...30 V for state 1; -3...5 V for state 0
-
Response time: 5.25 ms off-to-on, 5.75 ms on-to-off
-
Input filtering: 5 ms to suppress noise
-
Protection: Reverse polarity protection and integrated fuse on PDM (time lag 5 A)
-
Insulation: 1500 V for 1 minute between channels and logic bus
These specifications make the Schneider STBDDI3615K ideal for applications requiring fast, accurate discrete input reading with high immunity to electrical disturbances.
Industry Applications
The Schneider STBDDI3615K excels in manufacturing lines, packaging machinery, and conveyor systems. For instance, connect limit switches or proximity sensors to the six inputs to monitor part presence. The 5 ms input filtering prevents false triggers from vibration or electrical noise, ensuring reliable operation in harsh factory floors. The hot-swap capability (with basic NIMs) minimizes downtime during maintenance.
Installation & Setup Guidance
Mount the Schneider STBDDI3615K on a symmetrical DIN rail using the included STBXBA1000 base. Then wire field devices to the provided 6-terminal connectors—choose screw terminals for permanent installations or spring clamps for faster connections. The module supports cold and hot swapping, so you can replace it without powering down the entire system when using basic NIMs. Ensure the power distribution module (STBPDT3100/3105) supplies 24 V DC and observe the maximum voltage of 30 V.
Maintenance & Reliability
The Schneider STBDDI3615K operates in temperatures from 0 to 60 °C and withstands 95% relative humidity without condensation. Its IP20 protection allows use in clean industrial cabinets. Regularly inspect the connectors for tightness and check the green LED indicators (module status and per-channel) for immediate fault detection. The vibration resistance up to 3 gn at 58–150 Hz ensures reliable operation on moving equipment.
Compatibility & Integration
This kit integrates seamlessly with Modicon STB distributed I/O systems. Use it with the STBXBA1000 base and power distribution modules. The Schneider STBDDI3615K communicates via the STB backplane and is compatible with Allen-Bradley, Siemens, and other PLCs through the Modicon STB network interface modules. Always verify your system's power supply and base compatibility before ordering.
