Physical Dimensions and Component Layout

This unit measures 3.5 cm in length and 9.5 cm in width. Its total height reaches 6.2 cm including the D-sub connector. 1SAP210000R0001 weighs just 0.09 kg for DIN rail mounting. You will find 52 discrete components on a four-layer PCB.

Moreover, the unit integrates a 47 µF capacitor for supply filtering. This capacitor smooths noise on the 24V DC rail. LED indicators show bus activity and module power status.

Profibus DP Communication

The unit supports data rates from 9.6 kbps up to 1.5 Mbps. Auto-detection selects the correct baud rate without configuration. A rotary switch sets the Profibus station address from 0 to 125. An integrated bus terminator switch ensures proper line termination.

Signal Isolation and Protection

Optical isolators provide 1500V AC isolation between bus and logic. This design prevents ground loops from disrupting network communication. Transient suppression diodes protect against voltage spikes on the bus. LED indicators show data exchange and diagnostic status.

Typical Application Scenarios

You can deploy 1SAP210000R0001 in ABB AC500 systems with Profibus DP networks. It also works well for connecting remote I/O stations and drives. This unit links distributed field devices to the central CPU. Its compact size suits space-constrained control cabinets.
