Function and Positioning

Third-generation 10.4-inch high-performance, compact industrial PC terminal

128MB large memory, smooth multi-task processing, suitable for complex processing programs

33GB industrial electronic disk, stable storage, suitable for long-term operation conditions

Single expansion slot (S): lower cost, more compact structure, meets basic communication requirements

Compact keyboard (SA): saves installation space, suitable for compact cabinets

Targeted at mid-to-high-end CNC machine tools, automation lines, robot workstations, especially suitable for scenarios without the need for multiple fieldbus expansions

Different from BTV20.3SA-28B-33C-D-FW

Expansion slot: S = single expansion slot vs D = double expansion slot

Expansion capability: S only supports 1 type of fieldbus; D can simultaneously support 2 types

Cost: S is more economical; D has stronger expansion capability and a higher price

Application scenarios: S is suitable for basic communication, budget-sensitive, and space-constrained projects; D is suitable for mixed control of multiple brands, complex bus architecture projects

Compatible accessories

Industrial Ethernet shielded cable

AC 115–230V industrial power module

Embedded installation bracket + sealing gasket

Optional: single type of fieldbus communication card (Profibus-DP/INTERBUS, choose one)

Application fields

Mid-to-high-end CNC lathes, milling machines, machining centers

Automation assembly lines, inspection equipment, robot workstations

Automobile manufacturing, aerospace, mold processing

Strict working conditions with limited installation space, budget optimization, and no need for multiple bus expansions

Schaeffler high-end system matching, single brand control scenario
