System compatibility

0-57421 belongs to RELIANCE AutoMax DCS5000 series pulse tach input module.

Installed into AutoMax rack,work with AutoMax CPU 0-57407,drive control module 57406 and resolver module 57411.

Collect pulse signal from pulse tachometer or incremental encoder for motor speed and rotation direction monitoring.

Widely matched with Reliance MaxPak DC drive systems.

Support terminal cable assembly 57C372 for field wiring connection.

Commonly used for old DCS and drive equipment maintenance and spare replacement.

Function

0-57421 is pulse tachometer feedback acquisition module for RELIANCE AutoMax system.

Receive A/B quadrature pulse and Z marker pulse from incremental encoder or pulse tachometer.

24-bit counter records pulse number to calculate real-time motor rotational speed.

Identify forward/reverse rotation direction according to A/B phase sequence.

24-bit comparator supports preset pulse latch and count stop function.

8 read/write registers for data exchange with AutoMax program tasks.

Onboard multi LED indicators for module status,rotation direction,latch and count stop alarm.

Installation

Power off the whole AutoMax rack and cut main power supply.

Insert 0-57421 module into designated rack slot.

Lock module retaining clips.

Connect backplane bus and 57C372 terminal cable assembly to encoder field wiring.

Encoder cable adopt shielded twisted pair and separate from high voltage power cable.

Power on system,configure pulse parameters and test direction recognition.

Verify speed sampling and preset latch function.

Interface

AutoMax backplane edge connector,signal port for 57C372 cable assembly,CCLK OK,REVERSE,FORWARD,LATCH,CLEAR,COUNT STOP LED indicators.

Feature

RELIANCE 0-57421,AutoMax pulse tachometer speed input module.

Support quadrature A/B phase plus Z marker pulse input.

24-bit high precision counter and comparator for pulse measurement.

500V RMS isolation protects rack backplane from field surge.

Dedicated LED group for speed,rotation direction and pulse latch diagnosis.

Matched with 57C372 terminal cable assembly for convenient field wiring.

Discontinued obsolete module,supply only for old automation system spare replacement.

Suitable for metallurgy,paper-making heavy-duty production line drive speed control renovation.

Diagnostic

Speed value jitter:encoder cable damage or wiring interference;

No pulse input:tach power missing or connector poor contact;

Direction detection abnormal:A/B phase wiring reversed;

Latch function failure:comparator parameter setting error;

Module fault LED on:backplane communication failure or module circuit damage.

Product Brief

RELIANCE 0-57421 is AutoMax pulse tach input module.

It collects quadrature pulse signal from tachometer encoder to calculate motor speed and rotation direction for closed-loop drive control,widely used as spare part for heavy industry automation system maintenance.
