System compatibility

BTV20.3SA-56B-45C-S-FW belongs to Rexroth Indramat BTV20 visualization terminal family,matching Indramat System200 CNC and motion control systems,widely deployed on heavy-duty CNC machine tools and production automation lines.This is a legacy spare part for industrial equipment maintenance replacement.

Function

BTV20.3SA-56B-45C-S-FW is an expandable industrial PC-based operator terminal working under ISP mode.It integrates 10.4" TFT color screen,smart card reader and full machine keyboard,supports CNC program editing,manual axis jog,operation mode switching,parameter configuration,spindle & feed override adjustment,real-time machine status and fault alarm display.It communicates with main CNC controller via Ethernet and RS485 SIS bus for command transmission and data feedback.The 45C variant is equipped with factory preloaded dedicated firmware,the S suffix stands for smart card interface version.

Installation

Install BTV20.3SA-56B-45C-S-FW on cabinet panel cutout.Tighten mounting fixtures.Connect 115~230V AC power and communication cable according to wiring diagram.Check cable shielding and connector tightness before power-on commissioning.

Interface
