OTB1C0DM9LP | Schneider I/O Distributed Module Supplier

Introduction to the OTB1C0DM9LP

When your automation system demands reliable distributed I/O, the OTB1C0DM9LP delivers. This Schneider Modicon OTB module combines 12 discrete inputs and 8 outputs on a CANopen bus, supporting transmission speeds from 10 kbit/s to 1 Mbit/s. Its robust design ensures consistent performance in industrial environments.

Key Features & Technical Specs

• Discrete inputs: 12 conforming to EN/IEC 61131 type 1, sink or source logic.
• Discrete outputs: 2 solid state PNP and 6 relay, with source logic for Q0...Q1.
• Input voltage: 24 V DC, limits 20.4...26.4 V.
• Output voltage: 24 V DC solid state, 240 V AC or 30 V DC relay.
• Bus length: up to 1000 m at 50 kbit/s with tap-off up to 120 m.
• Power consumption: 19 W.
• IP20 protection, operating temperature 0...55 °C.

A standout spec is the configurable filtering time (0, 3, or 12 ms), allowing engineers to tailor noise immunity for specific applications.

Industry Applications

In manufacturing lines, the OTB1C0DM9LP excels at controlling actuators and sensing inputs. For instance, its 6 relay outputs can switch up to 2000 mA each, suitable for motor starters or solenoid valves. The 12 discrete inputs handle both NPN and PNP sensors, simplifying wiring in mixed-signal environments. Consequently, this module reduces cabinet space and wiring complexity.

Installation & Setup

Mount the OTB1C0DM9LP on a 35 mm DIN rail using the included clips, or panel-mount with a fixing kit. Connect via the removable screw terminal block for I/O wiring. For CANopen, use daisy-chaining or tap junctions with two twisted shielded pairs. Ensure supply voltage stays within 20.4...26.2 V DC to avoid inrush current peaks up to 50 A.

Maintenance & Reliability

With electrical durability of 500,000 cycles for relay outputs under AC-1 loads, the module offers long service life. Regularly inspect connections and verify LED status (green for I/O, PWR, RUN; red for ERR). The IP20 enclosure protects against dust, while the 0...55 °C operating range suits most factory floors. This reliability minimizes unplanned downtime.

Compatibility & Integration

The module integrates seamlessly with CANopen networks supporting DS 401 V2.1 profile. It connects to Schneider PLCs and other CANopen masters. Up to 63 slaves can be linked per segment, with bus lengths up to 5000 m at 10 kbit/s. For expansion, add up to 7 I/O expansion modules with various terminal types.
