The Schneider Electric STBDDI3615K forms part of the Modicon STB distributed I/O family. This kit provides six discrete input channels for your automation network. You receive a complete package ready for installation.
This kit contains four key components. First, the STBDDI3615 module handles all signal processing. Second, the STBXBA1000 base provides mechanical and electrical connections. Third, you get a STBXTS1100 6-terminal screw type connector. Fourth, the STBXTS2100 6-terminal spring clamp connector offers an alternative wiring method.
Many users appreciate the flexibility of two connector types. You can choose screw terminals for permanent installations. Alternatively, use spring clamps for faster wiring changes. Additionally, this kit supports both cold and hot swapping.
The STBDDI3615K follows EN/IEC 61131-2 type 1 standards. Each input channel accepts 24V DC signals with positive logic. The input current measures 4.5 mA per channel.
Key electrical parameters include:
On-state voltage range: 15 to 30V DC
Off-state voltage range: -3 to 5V DC
Guaranteed on-state current: 2.5 mA minimum
Guaranteed off-state current: 0.5 mA maximum
Absolute maximum voltage: 56V for 1.3 ms
The response time reaches 5.25 ms for off-to-on transitions. For on-to-off, it takes 5.75 ms. Input filtering is set to 5 ms by default. This filtering helps reject electrical noise from industrial environments.
Furthermore, this module includes robust protection features. Reverse polarity protection prevents damage from incorrect wiring. An input protection resistor limits current during faults. The power distribution module also contains a 5A time lag fuse.
The Schneider Electric STBDDI3615K provides 1500V AC isolation between channels and the logic bus for one minute. This high isolation level enhances system reliability. It protects your controller from field wiring faults.
This kit works with specific power distribution modules. Use it with the STBPDT3100 or STBPDT3105. These modules supply the required 24V DC field power. The logic bus draws 45 mA at 5V DC from the network interface module.
Status indicators help with troubleshooting. A green RDY LED shows module status. Additionally, six green LEDs display channel states for IN1 through IN6. Each LED lights up when the corresponding input detects an on-state signal.
The STBDDI3615K has compact dimensions. It measures 125 mm wide, 18.4 mm high, and 65.1 mm deep. Total weight reaches only 0.112 kg. This small footprint saves valuable cabinet space.
Operating temperature ranges from 0°C to 60°C without derating. Storage temperature spans from -40°C to 85°C. Relative humidity tolerance reaches 95% at 60°C without condensation. The IP20 protection rating meets EN 61131-2 class 1 standards.
Vibration resistance depends on the DIN rail type. For a 35 x 7.5 mm symmetrical rail, it withstands +/-0.35 mm at 10-58Hz and 3gn at 58-150Hz. For a 35 x 15 mm rail, it handles 5gn at 58-150Hz. Shock resistance reaches 30gn for 11ms.
Follow these steps to install the Schneider Electric STBDDI3615K:
Mount the STBXBA1000 base onto a DIN rail.
Click the STBDDI3615 module into the base.
Choose either screw or spring clamp connector.
Wire field devices to the selected connector.
Insert the connector into the module's front.
First, ensure power is disconnected before installation. Next, verify compatibility with your power distribution module. Then, connect the 24V DC supply correctly. Finally, test each input channel with a signal source.
Remember that this kit supports hot swapping. You can replace the module without powering down the system. However, always verify that your network interface module permits hot swapping first.

1. Can I use the STBDDI3615K with any Modicon STB system?
Yes, the Schneider Electric STBDDI3615K works with all Modicon STB distributed I/O solutions. Just ensure you have a compatible power distribution module like the STBPDT3100 or STBPDT3105.
2. What is the advantage of having two different connectors?
The screw connector suits permanent installations where vibration is minimal. The spring clamp connector allows faster wiring changes and handles vibration better. You can choose the best option for each application.
3. Is the STBDDI3615K hot swappable?
Yes, this module supports hot swapping when used with basic network interface modules. You can replace it without shutting down the entire system. This feature minimizes production downtime.
4. What happens if I connect reverse polarity?
The built-in reverse polarity protection prevents damage. The module simply will not operate correctly until you correct the wiring. No internal components will be harmed.
5. How far can I run input wiring from this module?
For unshielded cable, keep distances under 30 meters. For longer runs, use shielded cable and separate the wires from power cables. The 5 ms input filter helps reject induced noise.
