What Is the STBDDI3610K?
When your Modicon STB distributed I/O system needs reliable digital input acquisition, the Schneider STBDDI3610K standard digital input kit delivers a compact and flexible solution. This kit includes the STBDDI3610 module, a 6-terminal spring clamp connector (STBXTS2100), a 6-terminal screw type connector (STBXTS1100), and a base (STBXBA1000). It provides six discrete inputs at 24 V DC, supporting both positive and negative logic for versatile wiring. With its IP20 protection and CE marking, this kit is built for industrial control environments.
Technical Specifications Breakdown
The STBDDI3610K operates with a rated supply voltage of 24 V DC and accepts input voltage limits of 15...30 V at state 1 and -3...5 V at state 0. The permissible voltage is 30 V, with an absolute maximum of 56 V for 1.3 ms. Each input draws 4.5 mA, with state 0 current guaranteed at ≤0.5 mA and state 1 at ≥2.5 mA. Response times are 1.21 ms off-to-on and 1.74 ms on-to-off, ensuring fast signal detection. The kit includes input filtering of 1 ms and insulation between channels and logic bus rated at 1500 V for 1 minute. Power protection is provided by an integrated fuse on the PDM (time lag 10 A), along with input protection (resistor-limited) and reverse polarity protection.
Industry Applications
In manufacturing lines, the STBDDI3610K captures discrete sensor signals for monitoring conveyor status or machine safety interlocks. Its 24 V DC inputs and fast response times suit high-speed sorting applications. For building automation, the kit interfaces with limit switches or push buttons, leveraging its positive or negative logic to match existing wiring schemes. The hot swapping capability (for standard NIMs) reduces downtime during maintenance or expansion.
Installation & Setup Guidance
Mount the STBDDI3610K on a 35 x 7.5 mm or 35 x 15 mm symmetrical DIN rail. Use the included spring clamp or screw type connectors for field wiring. Connect the power distribution module STBPDT3100/3105 to supply 24 V DC. The base STBXBA1000 ensures proper alignment and electrical connection. Verify that the input voltage stays within 15...30 V for state 1 and -3...5 V for state 0. The kit supports cold swapping and hot swapping with standard NIMs, simplifying module replacement without powering down the entire system.
Maintenance & Reliability
Regularly inspect the STBDDI3610K for dust or debris on the IP20-rated enclosure. Check that the 10 A fuse on the PDM is intact. Operate within the ambient temperature range of -25…70 °C (without derating) and store at -40…85 °C. The kit withstands vibration up to 3 gn at 58…150 Hz on 35 x 7.5 mm DIN rail and shock resistance of 30 gn for 11 ms. These environmental tolerances ensure long service life in demanding industrial settings.
Compatibility & Integration
The STBDDI3610K is part of the Modicon STB distributed I/O solution family. It is compatible with the I/O base STBXBA1000 and power distribution modules STBPDT3100/3105. The kit integrates seamlessly with standard NIMs for hot swapping. Its 24 V DC inputs work with a wide range of sensors and switches, making it a flexible choice for system expansion.
Selection Guide & Purchasing Advice
Before ordering the STBDDI3610K, confirm that your system uses Modicon STB distributed I/O and requires 24 V DC discrete inputs. Verify the required connector type (spring clamp or screw) and ensure the base STBXBA1000 is included. The kit weighs 0.112 kg and measures 125 mm wide, 18.4 mm high, and 65.1 mm deep.
