Schneider Electric TSXDST1682 Modicon TSX Premium Series

The Schneider Electric TSXDST1682, also cataloged as the TSXDST1682 Digital Output Module, operates as a dedicated hardware component for transistor-based DC switching tasks within Modicon TSX Premium PLC systems. This module coordinates 16 solid-state channels, sending discrete actuation command loops directly to fields-side loads such as solenoids and relays without secondary electrical relay intermediaries.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks and I/O Density Scaling

The internal circuitry of the TSXDST1682 interfaces directly with standard rack backplanes to allow localized I/O density scaling up to 16 points per physical slot. When connected via upstream network couplers, its rapid response time (<= 0.5 ms) ensures synchronous integration with Profinet / EtherNet/IP deterministic networks. The transistor switching matrix processes internal bus commands under strict real-time conditions, suppressing network jitter and preserving overall industrial bus timing metrics during multi-channel execution loops.

Frequently Asked Questions

Q: Can the TSXDST1682 solid-state transistor channels switch 120 VAC or 230 VAC inductive load circuits directly?

A: No. This hardware component is specifically restricted to 24 VDC transistor configurations. Applying alternating current (AC) loads will cause thermal runaway and permanent failure of the internal switching components.

Q: Is hot-swapping of this module permitted inside the active Modicon TSX Premium rack assembly?

A: No. Removal or insertion of the TSXDST1682 while the rack backplane is energized can induce transient electrical noise, potentially corrupting active data loops or triggering major system errors on the main controller.

Q: How does the maximum module current restriction affect individual channel operations?

A: Although each independent channel is rated to supply up to 0.5 A, the aggregate current passing through all 16 channels must not exceed 8 A simultaneously to prevent internal trace overheating.

Field Installation Guidelines

• Enclosure Requirements: All rack assemblies containing the TSXDST1682 must reside within an industrial control cabinet providing IP20 ingress protection. Shield the environment from airborne particulates and condensation.
• Grounding and Shielding Protocols: Verify low-resistance metal-to-metal continuity between the rack chassis and the primary enclosure earth ground bus. Ground the shields of all inductive field lines to dedicated external terminal bars rather than the module frame.
• Cable Routing Constraints: Maintain distinct physical separation between low-voltage 24 VDC signal cables and high-power AC lines or variable frequency drive (VFD) output cables to minimize magnetic and electrostatic coupling.
