Schneider STBDAI7220 230V AC Digital Input Module

Schneider STBDAI7220 Modicon STB Input Module

Product Introduction

The Schneider STBDAI7220 belongs to the Advantys STB distributed I/O platform. This standard digital input module provides 2 channels for 230V AC signal acquisition. Specifically, it complies with IEC/EN 61131-2 Type 1 standards. Therefore, it suits industrial environments where reliable AC signal detection is essential. The STBDAI7220 module features robust electrical isolation and supports hot swapping operations. Consequently, maintenance becomes easier without shutting down the entire system.

Technical Specifications

This module operates with a field voltage range of 159V to 256V for state 1 signals. Meanwhile, the state 0 voltage range stays between 0V and 40V. The input frequency spans 47Hz to 63Hz, accommodating common industrial power networks. Additionally, the response time for both on-to-off and off-to-on transitions is 1.5 ms. This fast response ensures timely signal processing for control logic.

The Schneider STBDAI7220 draws 40 mA at 5V DC from the logic bus. Furthermore, the electrical isolation between channels and the logic bus reaches 1780V RMS for one minute. This high isolation protects the bus side from field voltage spikes. Besides, the module integrates short-circuit and overload protection features.

Mechanical and Environmental Parameters

The module dimensions measure 18.4 mm wide, 125 mm high, and 65.1 mm deep. In addition, the product weighs only 0.122 kg. Its compact form factor allows efficient DIN rail mounting in control cabinets.

For environmental tolerance, the operating temperature ranges from 0°C to 60°C without derating. Meanwhile, storage temperature extends from -40°C to 85°C. The module also withstands 95% relative humidity at 60°C without condensation. Moreover, it resists vibration at 3 gn on standard 35 mm DIN rails.

Installation Guide

First, mount the compatible STBXBA2000 I/O base onto a 35 mm DIN rail. Next, align the STBDAI7220 module with the base and press it firmly into position. After that, connect the field wiring to the 5-terminal connector. Additionally, ensure the power distribution module STBPDT2100 supplies the required 230V AC field power. Finally, verify the green RDY LED illuminates to confirm proper operation.

The module supports hot swapping when used with standard NIMs. However, always follow local electrical codes during installation. For instance, de-energize field circuits before making wiring connections if safety procedures demand it.
