ABB 57160001-TZ DSTD 110A S100 I/O Connection Unit

Description

The ABB 57160001-TZ DSTD 110A is a termination connection unit designed for interfacing digital output signals within ABB industrial control platforms. Serving as a core connection component for the S100 I/O system, it routes signals between field devices and central processing sub-racks across Advant Controller 450, Advant OCS with Master SW, MasterPiece 200/1, MOD 300, and 800xA control architectures.

Engineered specifically for digital output board applications—such as the DSDO 115 series—the 57160001-TZ DSTD 110A accommodates up to 32 digital output channels with a maximum operating voltage rating of 60 V. The unit acts as a field wiring termination interface, providing organized point-to-point connections for discrete signals while simplifying field cable management inside cabinet enclosures.

The ABB DSTD 110A features a compact physical footprint measuring 157.5 mm wide by 54 mm high by 324 mm deep, allowing convenient mounting on standard cabinet sub-racks or mounting rails. It serves as a field-proven termination interface in both existing legacy systems and updated DCS I/O configurations requiring reliable channel termination.

Features

• 32-Channel Capacity: Designed to support up to 32 discrete channels for digital output board connection.
• 60 V Maximum Rating: Standard voltage handling capability rated at a maximum of 60 V for industrial digital output signals.
• S100 I/O System Integration: Directly compatible with ABB S100 I/O termination structures and digital output kits such as DSDO 115K12 and DSDO 115K01.
• Multi-Platform Support: Integrates across ABB control platforms including Advant Controller 450, MasterPiece 200/1, Advant OCS with MOD 300 SW, System 800xA, and Compact Product Suite.
• Compact Physical Design: Standard panel dimensions of 157.5 mm x 54 mm x 324 mm ensure space-efficient cabinet integration.

Applications

• Digital Output Signal Termination: Interfacing 32-channel digital output modules (e.g., DSDO 115 series) with field-side actuators, solenoids, and switching relays.
• Advant Master & 800xA System Expansion: Serving as the field connection point for S100 I/O racks in Advant Controller 450 and System 800xA DCS installations.
• Cabinet Retrofits and Maintenance: Direct replacement termination unit for legacy MasterPiece 200/1 or MOD 300 I/O subsystems.

Installation Guidelines

1. Safety Isolation: Disconnect system power to the targeted I/O rack and field circuits prior to starting work.
2. Pre-Installation Inspection: Verify that the connection unit part number matches 57160001-TZ (DSTD 110A) and inspect terminal blocks for physical integrity.
3. Mounting: Secure the unit in the designated I/O cabinet space using the compatible mounting screws kit (3BSE021202R1).
4. System Cable Attachment: Connect the system ribbon/interface cable from the S100 I/O digital output board to the unit's board interface.
5. Field Wiring: Land field digital output conductors onto the designated channel terminals, ensuring proper tightening torque and line polarization.
6. Grounding & Shielding: Ensure all cable shields and grounding connections meet ABB S100 I/O cabinet installation standards.
7. Commissioning Check: Confirm channel signal continuity and check for correct potential before re-energizing field circuits.
