Product Description:

The BTV20.3SA-56B-45C-D-FW operator panel is built by Bosch Rexroth Indramat for the BTV20 Machine Operator Panels series. Within an automated cell, the panel provides combined display, keyboard, and control signaling so that a PLC or motion controller can be supervised from a single enclosure. Belonging to the wider BTV panel product family, it is intended to mount on the front of a machine where it translates operator commands into drive or CNC instructions through its integrated electronics. This arrangement allows status messages, process prompts, and manual commands to be handled directly at the point of operation.

Hardware resources are sized for mid-range control tasks. The base system runs at a minimum processor speed of 700 MHz and integrates an RS485 port for distance-tolerant serial communication with decentralized drives. Volatile storage totals 256 MB of RAM, and nonvolatile primary storage is a 3.5-inch floppy disk drive that accepts 1.44 MB media for parameter backup or software transfer. Power is supplied over an input range of 115 to 230 V AC at 50 to 60 Hz, allowing the unit to share mains feeds with typical cabinet equipment. A standard keyboard is factory installed for direct local input during operation.

User interaction is organized around 16 machine function keys, each of which can be mapped to frequently used cycles or diagnostics in the PLC program. The enclosure follows Design 3, giving consistent mounting dimensions across the series, while the panel function type is classified as ISP, indicating that operator inputs are interpreted locally before being forwarded to the supervisory computer. Inside product line 20, this variant is intended for machine-front operation where local command entry and status access are needed during routine use. That layout supports quick access to common machine functions during setup, monitoring, and normal production changes.
