Schneider STBDDI3230 Digital Input Module

Schneider STBDDI3230 2-Channel Digital Input Module

Product Introduction

The STBDDI3230 from Schneider Electric belongs to the Advantys STB series. This standard digital input module captures two 24V DC signals from field devices. Engineers use it in factory automation, packaging lines, and machine control. As a result, the module adds flexible input points to any Advantys STB island.

Technical Specifications

The STBDDI3230 provides two digital input channels with sink wiring. Each channel accepts a 24V DC signal that meets IEC/EN 61131-2 Type 2. Moreover, the module delivers 1500V DC field-to-bus isolation for one minute. This isolation protects the bus side from field surges. In addition, the module supports hot swapping, so you can replace it without stopping the island.

Key parameters at a glance:

• Module type: Standard digital input module

• Channels: 2 (sink)

• Signal type: 24V DC, IEC/EN 61131-2 Type 2

• Isolation: 1500V DC field-to-bus for 1 minute

• Hot swapping: Yes

• Bus current: 60 mA at 5V DC

Electrical and Base Requirements

The STBDDI3230 receives its 24V DC supply through a PDM. Specifically, pair it with the STBPDT3100 PDM for 24V DC operation. The module draws 60 mA at 5V DC from the island bus. Additionally, it mounts on the STBXBA1000 I/O base, which measures 13.9 mm wide. Therefore, plan your island layout with the correct base and PDM before installation.

Mechanical and Environmental Parameters

The module weighs only 0.110 kg, so it adds little load to the DIN rail. Meanwhile, the IP20 rating means the unit suits clean, dry control cabinets. The operating and storage temperature ranges are not available in current data. However, typical Advantys STB modules work in standard industrial environments. Please confirm thermal limits with Schneider Electric before harsh deployments.

Installation Guide

First, snap the STBXBA1000 base onto a standard DIN rail inside the cabinet. Next, attach the STBPDT3100 PDM to supply 24V DC field power. Then, slide the STBDDI3230 onto the base until it clicks into place. After that, wire the field devices to the input terminals according to the sink wiring diagram. Finally, set the module address through the island configuration software. Because the module supports hot swapping, you can swap it later without powering down the island. Additionally, verify the Type 2 input threshold to match your sensor output.

Lifecycle Note

Schneider Electric lists the STBDDI3230 as discontinued. The Modicon X80 range now replaces this Advantys STB product. Therefore, buyers should check stock carefully before ordering. We still supply new surplus and refurbished units for legacy systems.
