ABB SNAT602TAC 61001395G1 Drive Terminal Interface Board

The ABB SNAT602TAC 61001395G1 is a dedicated terminal and signal interface board designed for ABB DCS800 and legacy DC drive systems. It creates reliable wiring interfaces between the main APC control card, external sensors, relays and field I/O signals for precise DC motor drive regulation.

This plug‑in printed circuit board is equipped with multiple relay outputs and screw terminal blocks for convenient field wiring. Original production has been discontinued. It is widely stocked as aftermarket spare parts for metallurgical, paper and heavy‑industry DC drive cabinet maintenance and retrofit projects.

Main Specifications

Core Functions

1. Establish physical signal wiring channels between the drive main control board and on‑site field devices.
2. Receive speed, current and thermal feedback signals from DC motors and convert them into standard logic signals.
3. Output relay switching signals for safety interlocks, fault alarms and auxiliary equipment control.
4. Filter and isolate field electrical noise to protect the main control card from surge interference.
5. Transmit drive fault codes and operating status back to the upper monitoring system in real time.
6. Serve as the front‑end wiring and signal conditioning interface of the complete DC speed regulation system.

Application Scenarios

1. Metallurgical rolling mills, paper machines, mine hoists and heavy‑duty DC motor speed control systems.
2. Spare interface board replacement and routine maintenance of existing ABB DCS800 drive control cabinets.
3. Technical renovation and signal stability upgrade of aging large‑capacity DC variable‑speed drives.
4. On‑site troubleshooting and replacement of faulty terminal boards on continuous heavy industrial production lines.
5. Spare‑parts stocking for system integrators and ABB DC drive automation maintenance contractors.
6. Global aftermarket spare supply for technicians maintaining obsolete ABB legacy DC drive hardware.

FAQ

1. Q:What is the difference between SNAT602TAC and 61001395G1?
