Technical Specifications Model:0-49009-3 Brand:RELIANCE Product type:Transductor Board Weight:1.08kg Dimension:231mm161mm28mm Operating temperature:0℃ ~ 60℃ Storage temperature:-40℃ ~ +85℃ Relative humidity:5%~85%,non-condensing Certification:CE

System compatibility 0-49009-3 belongs to RELIANCE CardPak series transductor board. Installed into CardPak rack,works with regulator board and limit protection module. It samples main AC current and converts isolated analog feedback signal for CardPak DC drive system. Commonly used for old industrial DC drive equipment maintenance and spare replacement.

Function 0-49009-3 is dedicated transductor signal conversion module for RELIANCE CardPak DC drive system. Sample SCR main loop AC current and convert to proportional low-level analog signal. Provide galvanic isolation between high-power main circuit and low-voltage control circuit. Transmit converted current feedback signal to regulator board for closed-loop current regulation. Onboard factory adjustment potentiometer for signal gain calibration. Suppress commutation noise from SCR power components. Supply current magnitude signal for over-current protection logic.

Installation Power off the whole drive cabinet and cut main power supply. Insert 0-49009-3 board into designated CardPak slot and lock retaining latch. Connect backplane bus connector and current monitoring wiring. Separate low voltage control wiring from high power main circuit cable. Power on system,calibrate output signal via front adjustment potentiometer. Verify sampling signal stability under no-load and rated load.

Interface Backplane bus connector,current signal input & output terminal,calibration potentiometer,status LED indicators.

Feature RELIANCE 0-49009-3,CardPak rack mount transductor board. High voltage isolation for safety between power side and control side. AC current sampling and analog signal conversion. Front panel potentiometer for field calibration. Built-in filtering circuit for SCR commutation interference suppression. 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 Drive current unstable:transductor calibration drift or signal interference; Inaccurate current feedback:potentiometer misadjustment or component aging; No current feedback signal:backplane connector poor contact; Frequent overcurrent false trip:signal distortion caused by component degradation; Regulator board current alarm:transductor output overload.

Product Brief RELIANCE 0-49009-3 is CardPak transductor board. It samples main circuit current and outputs isolated analog feedback signal for Reliance CardPak DC drive,widely used as spare part for legacy DC drive equipment maintenance.
