Physical Specifications: 17.5mm W x 100mm H x 110mm D, DIN rail mounting.

Environmental parameters: Operating temperature 0°C ~ +60°C, IP20 protection (requires installation in the cabinet).

Diagnostic function: LED real-time display of channel status, power and communication failure, support relay contact wear detection.

Certification compliance: CE, UL certified, in accordance with IEC 61131-2, EN 50155 (rail transportation) standards.

ABB DSTX170 supports Modbus RTU, Profibus DP and other industrial standard protocols, and can be seamlessly integrated with ABB S800 I/O system and third-party PLC/DCS.

The modular design of ABB DSTX170 allows it to be used in combination with other S800 I/O modules (such as analog I/O and communication gateways) to meet the needs of complex industrial scenarios.

The ABB DSTX170 supports 230V AC/DC load voltage, 3A continuous current (6A peak) on a single channel, and is compatible with inductive, capacitive and resistive loads.

With built-in relay contact wear detection and fuse blowing alarms, the ABB DSTX170 monitors channel status in real time via LEDs to minimize the risk of unplanned downtime.

Efficient Diagnostics and Maintenance

Hot-swappable function Supports the replacement of modules with power, together with the redundant bus configuration, realizing zero downtime maintenance.

Extended MTUs (TU836/TU837) provide single-channel independent fuses (up to 3A) for enhanced overcurrent protection.
