Schneider Electric OTB1CODM9LP

The Schneider Electric OTB1CODM9LP is a distributed I/O interface module from the Advantys OTB (Optimized Terminal Block) series. It is designed to allow a PLC to control I/O over a network, specifically acting as a CANopen slave node.¹

This “island” of I/O is ideal for decentralizing control, reducing the amount of wiring that needs to run back to the main electrical cabinet.

1. I/O Configuration

The OTB1CODM9LP is an “all-in-one” base module that includes integrated digital I/O:

• Digital Inputs: 12 inputs (24V DC, Sink/Source).²

   

• Digital Outputs: 8 outputs.

  • 6 are Relay outputs (2A).

  • 2 are Transistor outputs (0.3A).

• Expandability: You can add up to 7 additional expansion modules (from the TM2 series) to the right side of this base, allowing for a total of up to 132 I/O points on a single CANopen node.³

   

2. Communication: CANopen

This specific model is defined by its communication protocol:

• Protocol: CANopen (conforms to DS301 profile).⁴

   

• Physical Interface: 9-pin D-Sub (Male) or screw terminal options for the CAN bus.

• Baud Rate: Auto-detects or manual setting from 20 kbps to 1 Mbps.

• Addressing: Set via two rotary switches (0–99) located under the front protective cover.
