Distributed I/O SystemsSuitable for distributed control scenarios of factory automated production lines and smart workshops. It enables module interconnection inside compact cabinets and supports signal conversion for remote I/O stations.
Legacy System RetrofitUsed for upgrading outdated ABB control systems including Advant Master and MasterPiece 200/200/1 series. It replaces aged connection units while maintaining compatibility with existing DSDP160 modules, cutting renovation costs.
Operating Instructions
Pre-installation Preparation
Model VerificationConfirm the product model is 57160001-MA (DSTX120), which is compatible with DSDP160 modules and S100 I/O boards (QGLF108).
Environment CheckThe operating temperature shall be kept between 0℃ and 55℃. The site shall be free of corrosive gas and severe vibration to meet industrial control requirements.
Tool PreparationPrepare a Phillips screwdriver, cable ties and anti-static wristband for operation in electrostatic-sensitive areas.
Installation Procedures
Unit MountingFix the DSTX120 unit onto cabinet rails or with screws. Reserve a 10 cm clearance for heat dissipation and do not block the ports.
Module ConnectionAlign the DSDP160 module with the DSTX120 port, insert it smoothly and fasten the screws to ensure a firm connection.
I/O Board ConnectionInsert the S100 I/O board (QGLF108) into the corresponding slot of DSTX120, and make sure the buckles are fully latched without looseness.
Cable ArrangementOrganize cables with ties to prevent tension on ports and keep wiring neat for easy subsequent maintenance.
Commissioning and Verification
Power-on InspectionAfter system power-up, check the status of indicator lights. The running light shall stay on steadily and the fault light shall remain off under normal operation.
Signal TestUse the control system software to verify normal I/O signal acquisition and output, with no signal loss or delay.
Stability TestRun the unit continuously for 24 hours. Check for overheating, loose connections and fault alarms to confirm stable operation.
Removal and Maintenance
Power CutoffCut off the system power before removal. Live operation is prohibited to prevent module damage.
Removal StepsLoosen the fixing screws, pull out the I/O board first, then remove the DSDP160 module. Handle the units gently to avoid port damage from collision.
FAQ
Q: Can DSTX120 directly replace other models of connection units?A: No. DSTX120 is a dedicated connection unit for DSDP160 and only compatible with S100 I/O board (QGLF108). It cannot replace other models such as DSTA120 and DSTC120. Always verify model and compatibility before replacement.
Q: Since the product is RoHS-exempt, can it be used for all EU projects?A: Yes. Granted specific exemption under the EU RoHS Directive and accompanied with ABB EU Declaration of Conformity (3BSE088609), it is applicable to projects subject to mandatory RoHS compliance across the EU and worldwide.
Q: Why are the indicator lights off after installation?A: Common causes:① Loose module connections. Re-seat DSDP160 module and I/O board, then tighten fixing screws.
② Abnormal system power supply. Check the power output of the cabinet.
③ Defective unit. Contact ABB technical support for inspection and replacement.
Q: Does DSTX120 require a separate power supply?A: No. This is a passive connection unit powered by the system bus. No extra power wiring is needed, which simplifies cabling and reduces potential failures.
Q: What is the warranty period?A: The warranty lasts 1 year. Repair or replacement is available for non-artificial damage. Q: Which model of S100 I/O board is compatible?A: It is exclusively designed for QGLF108 S100 I/O board and incompatible with other I/O board models. Place supporting orders together during procurement to avoid compatibility issues.
