Responsible for interlock signal exchange between each CardPak board and external system.
Compatible with AutoMax control system for heavy industry production line.
Commonly used for old DC drive equipment maintenance and spare replacement.
Function
518317 is dedicated signal interface PCB board for RELIANCE CardPak DC drive system.
Realize signal isolation and transmission between internal regulator boards.
Process external interlock,enable and emergency stop logic signal.
Integrated fault signal collection and latch function,collect overcurrent,overvoltage,pulse loss alarm.
Convert fault status to dry contact or analog signal for upper system feedback.
Onboard test points for interlock signal inspection and fault troubleshooting.
Provide hardware interlock protection chain to block SCR trigger signal under abnormal condition.
Installation
Power off the whole CardPak drive rack and cut main power supply.
Insert 518317 board into designated slot of drive rack.
Fasten fixing screws.
Connect backplane edge connector and external interlock wiring.
Separate low voltage logic cable and high voltage power cable.
Power on system,check enable chain and fault latch function.
Test emergency stop interlock and fault signal output.
Interface
CardPak backplane edge connector,external interlock terminal,fault signal output port,test measurement points,status and fault LED indicators.
Feature
RELIANCE 518317,CardPak drive signal interface printed circuit board.
Unified collection and latching of multi-channel drive fault signals.
Hardware safety interlock chain to inhibit SCR trigger when fault occurs.
Signal isolation circuit to prevent external interference from affecting control loop.
Multiple test points for convenient maintenance and onsite inspection.
Standard CardPak plug-in structure,easy replacement together with other regulator boards.
Discontinued obsolete board,supply only for old automation drive system spare replacement.
Suitable for metallurgy,paper-making heavy-duty DC drive production line renovation.
Diagnostic
Drive cannot enable:external interlock open or interface board logic fault;
Fault false latch:signal interference or component aging;
No fault signal output:feedback terminal loose or circuit damage;
LED abnormal:board auxiliary power supply failure;
Interlock failure:hardware protection circuit damage.
