Technical Specifications Model:0-49017-2 Brand:RELIANCE Product type:Speed Reference Board Weight:1.09kg Dimension:231mm161mm28mm Operating temperature:0℃ ~ 60℃ Storage temperature:-40℃ ~ +85℃ Relative humidity:5%~85%,non-condensing Certification:CE

System compatibility 0-49017-2 belongs to RELIANCE CardPak series speed reference board. Installed into CardPak rack,works with operational amplifier board and regulator board. It generates adjustable analog speed setpoint signal for CardPak DC drive system. Commonly used for old industrial DC drive equipment maintenance and spare replacement.

Function 0-49017-2 is dedicated speed reference setpoint board for RELIANCE CardPak DC drive system. Generate stable analog reference voltage corresponding to target motor speed. Onboard multi-turn potentiometer for manual speed setting. Provide ramp function for smooth speed increase and decrease. Receive external remote reference signal and switch between local/remote mode. Output reference setpoint to op-amp board for closed-loop speed control. Suppress reference signal drift caused by temperature variation.

Installation Power off the whole drive cabinet and cut main power supply. Insert 0-49017-2 board into designated CardPak slot and lock retaining latch. Connect backplane bus connector and analog reference signal wiring. Separate low voltage control wiring from high power main circuit cable. Power on system,calibrate reference range via potentiometer. Test local and remote speed setpoint switching.

Interface Backplane bus connector,analog signal input & output terminal,local adjustment potentiometer,status LED indicators.

Feature RELIANCE 0-49017-2,CardPak rack mount speed reference board. Local manual speed setpoint generation and remote signal selection. Built-in ramp timing for soft start and soft stop. Onboard potentiometer for reference range calibration. Temperature drift compensation circuit for stable setpoint output. Industrial PCB design for long continuous running in harsh factory environment. Discontinued obsolete board,supply only for old CardPak DC drive system spare replacement. Suitable for metallurgy,paper-making production line DC drive renovation.

Diagnostic Motor cannot reach set speed:reference potentiometer drift or calibration offset; Sudden speed jump:local/remote signal switching circuit failure; Slow speed response:ramp parameter misadjustment; No reference output:backplane connector poor contact; Reference value drift:thermal aging of internal precision resistors.

Product Brief RELIANCE 0-49017-2 is CardPak speed reference board. It provides local or remote analog speed setpoint signal for Reliance CardPak DC drive,widely used as spare part for legacy DC drive equipment maintenance.
