Product Description:

The BTV20.3SA-28B-45C-D-FW is an innovative industrial control panel. It's part of the BTV20 Machine Operator Panels series. The Bosch Rexroth Indramat designed and manufactured this control panel. This model has a dependable machine-level control.

The BTV20.3SA-28B-45C-D-FW has a slot for 200 MHz CPU. It includes an integrated graphics controller for display functions. The 128 MB RAM ensures smooth multitasking performance. It includes a 1.2 GB hard drive for robust data storage. It is encased in a compact and durable shell. This control panel features 16 function keys for manual configuration. The keys are positioned on both the left and right sides. The panel comes in 640 x 480 resolution along with a 10.4 inches TFT display (colored). The system is based on the ISP function type and includes PLC integration. The power supply is 115-230 VAC ±15% auto-range. The rated power consumption of this panel is 100 W and under high working conditions it increases to 200 W. The front cover of the BTV20.3 panel is protected under IP65 standard. The rear casing is rated IP20 for interior safety. Overall measurements without the panel are 372 x 335 x 200 mm. The panel has 10.5 kg weight and is light grey in color. It also comes with a 3.5-inch floppy disk drive along with 1.44 MB memory capacity.

The BTV20.3SA-28B-45C-D-FW combines control and visualization. Its 9-slot expandability provides setup versatility. The panel includes 9 open spaces for modular expansion. Supported cards include MTS-P01.1 PLC modules with 1-2 MB RAM. It also supports MTC-P01.2 CNC cards with eight-axis control. The panel includes an ISA Ethernet card option for network connection. Firmware must be acquired individually for this model.

Frequently Asked Questions about BTV20.3SA-28B-45C-D-FW:

Q: How does the IP65-rated front panel protect the BTV20.3SA-28B-45C-D-FW in factories?

A: It shields the internal electronics from dust and low-pressure water jets. This makes it suitable for installation in harsh, dust-prone machine environments.

Q: Why is a separate firmware order required for BTV20.3SA-28B-45C-D-FW?

A: The firmware depends on the system configuration and user application needs. This approach allows custom software deployment tailored to specific production setups.

Q: How does the integrated graphics controller improve panel performance?

A: It offloads display processing from the CPU, ensuring smoother visual operations. This is especially useful during multi-tasking or real-time display updates.

Q: Why is the floppy disk drive still included in BTV20.3SA-28B-45C-D-FW?

A: It is used for legacy data backup or firmware loading in industrial environments. Many production lines still rely on 3.5” media compatibility.

Q: How does the 9-slot expansion structure benefit users of BTV20.3SA-28B-45C-D-FW?

A: Users can insert customized modules for serial, network, or fieldbus communication. This design adapts easily to changing factory automation requirements.
