Schneider STBDAI7220 Advantys STB 230V AC Digital Input Module

Schneider Electric STBDAI7220 – Advantys STB 2-Channel 230V AC Digital Input Module

Model STBDAI7220 is a standard 2-channel digital input module from the Schneider Electric Advantys STB series. It accepts 230V AC signals and meets IEC/EN 61131-2 Type 1. The module supports hot swapping for fast maintenance. It uses a 1780V AC field-to-bus isolation for 1 minute. This module is discontinued and superseded by the Modicon X80 range. Last verified: 2026-09.

Technical Specifications

Measurement range: 230V AC nominal. Frequency response: 50/60 Hz standard. Sensitivity: Type 1 per IEC/EN 61131-2. Linearity: Not applicable for digital input. Resolution: 1 bit per channel. Temperature range: Not specified. Environmental resistance: IP20 rated. Noise immunity: 1780V AC isolation for 1 minute.

Installation Guide

• Mount the module on an STBXBA2000 I/O base (18.4 mm width).
• Use a STBPDT2100 PDM for 115/230V AC supply.
• Connect 230V AC field wiring to the 2 input channels.
• Ensure hot swapping is done with the system powered.
• Follow local electrical codes for 230V AC circuits.
• Maintain IP20 environment. Avoid dust and moisture.

Debugging and Maintenance Convenience

Hot swapping lets you replace the module without stopping the bus. Each channel has a clear status LED. The 1780V AC isolation protects the bus from field surges. No special tools are needed for removal. Keep spare STBXBA2000 bases and STBPDT2100 PDMs on hand. Regular visual checks are enough for most sites.

Compatibility Notes

• Works only with Advantys STB system.
• Requires STBXBA2000 I/O base.
• Requires STBPDT2100 power distribution module.
• Superseded by Modicon X80 range. Check migration path.
• Not compatible with 24V DC input modules.
