Overview
The ABB 3BHE025541R0101 PCD231B is a communications I/O module for the ABB AC 800PEC platform. It exchanges control and diagnostic data between connected automation devices through the documented PEC80-CCI system interface. Furthermore, its specified 24 VDC supply, 4 W typical power consumption and electrical isolation values provide key information for equipment identification and configuration checks.
Functional Description
The PCD231B handles communication data exchange within the ABB AC 800PEC control system. It transfers available control and diagnostic information between connected devices, allowing the associated automation equipment to exchange operational data.
Meanwhile, its communication data rates cover a range from 9.6 kbps to 12 Mbps. This range is relevant when checking communication requirements and matching the module to the configured system interface.
Electrical and Environmental Characteristics
The module uses a 24 VDC supply with a tolerance of +/-10% and has a typical power consumption of 4 W. Its documented isolation ratings include 1500 VAC and 3000 VAC output isolation. These values should be checked against the applicable circuit and interface requirements before replacement.
Furthermore, the operating temperature range is -25 to +60 deg C, while the storage range is -40 to +85 deg C. The specified humidity range is 5-95% RH, non-condensing.
