Schneider STBDAI5260 Isolated AC Input | Advantys STB

Schneider STBDAI5260 Digital Input Module

Product Introduction

The STBDAI5260 is a standard isolated digital input module built for the Schneider Electric Advantys STB distributed I/O platform. This 2-channel AC input kit reads 115V AC signals from field devices such as limit switches, selector switches, and AC proximity sensors. Furthermore, the isolated design separates each input channel, which reduces cross-talk in electrically noisy installations.

Technical Specifications and Input Capability

The STBDAI5260 module provides two discrete input channels with full isolation. Moreover, each channel accepts a 115V AC signal that conforms to IEC/EN 61131-2 Type 1 characteristics. Additionally, Type 1 inputs tolerate longer transition times, so they handle mechanical contacts and AC sensors without false triggering.

Isolation between field wiring and the logic bus reaches 1780V AC. Specifically, this rating protects the backplane and network interface from AC transients and ground potential differences. Besides, the isolated channel design keeps one faulted field circuit from disturbing its neighbor.

The STBDAI5260 also supports hot swapping when paired with a standard NIM. Meanwhile, that feature allows replacement without shutting down the entire island. Therefore, maintenance windows stay short in continuous-process environments.

Mechanical and Environmental Data

The STBDAI5260 mounts on the STBXBA2000 base unit, which measures 18.4 mm in width. The assembly carries an IP20 protection rating, so it belongs inside a control cabinet or protective enclosure. Furthermore, field power arrives through the STBPDT2100 power distribution module, which handles 115V or 230V AC.

Installation and Configuration Guidelines

First, mount the STBXBA2000 base onto a standard DIN rail. Next, slide the STBDAI5260 module onto its base until the locking mechanism engages. Then, connect the AC field wiring to the input terminals, keeping line and neutral runs separated from low-level signal cables.

Additionally, confirm that the STBPDT2100 supplies the correct AC voltage before commissioning. However, hot swap operation depends on the network interface type, so verify compatibility first. Finally, configure input filtering and addressing through the Advantys configuration software.

FAQ

Q1: How does the STBDAI5260 differ from the STBDAI5230?
The STBDAI5260 adds channel-to-channel isolation on top of field-to-bus isolation. The STBDAI5230 provides field-to-bus isolation only, so the 5260 suits noisier environments.

Q2: What signal type does this module accept?
The STBDAI5260 reads 115V AC signals that meet IEC/EN 61131-2 Type 1 requirements. That standard covers mechanical contacts and many AC proximity sensors.

Q3: What is the isolation rating on the STBDAI5260?
Isolation between field wiring and the logic bus reaches 1780V AC. The isolated channel design also limits interference between the two input circuits.

Q4: Which base and PDM does this input module need?
It uses the STBXBA2000 base at 18.4 mm width. Field power comes from the STBPDT2100 module, which supports 115V and 230V AC.

Q5: Is the STBDAI5260 still in production?
No, Schneider Electric has discontinued this module. The Modicon X80 range now serves as the recommended replacement path.
