Overview

The BC820K02 is an automation component from GE. Article number 3BSE071500R1 (BC820K02).

Application & Technical Notes

As an automation component, the BC820K02 is intended for deployment in panel-based control cabinets and machine enclosures where the GE product portfolio equipment is installed. It performs a defined automation function within the control system and is selected to match the installed GE platform.

Specific electrical and mechanical ratings depend on the exact configuration and suffix of the part; the original datasheet should be consulted for the definitive specification.

Maintenance & Diagnostics

Avoid condensation — the rated humidity is 5 to 95 %, non-condensing; store and operate the module in a dry, pollution-degree-appropriate enclosure. Inspect terminals and connectors for corrosion or looseness, and confirm the module seats correctly in its carrier. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.

Sourcing & Procurement

When sourcing the BC820K02, distinguish three supply tiers: (1) genuine GE stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.

Confirm mechanical and electrical compatibility with your GE product portfolio installation and the intended function. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.

General info

Dimensions

Note	Width 59 mm (2.9 in.) Height 185 mm (7.3 in.) Depth 127.5 mm (5.0 in.) Weight (including base) 1.4 kg (3.1 lbs) (BC820K02 package) The CEX-Bus unit BC820 is used for extending the onboard communication ports with communication interface units. It is also possible to use redundant communication interfaces on the CEX-Bus. The BC820 CEX-Bus Interconnection Unit offers a way to section the CEX-Bus into two independent segments up to 200 meters apart. This improves availability in systems with redundant communication interfaces. The BC820 can be used with PM858, PM862, PM866 (PR.F or later, which corresponds to PR:H or later for PM866K01), and PM866A. The BC820 is powered from the processor unit via the CEX-Bus and can also support the CEX-Bus with redundant power through its external connector for power supply. BC820 transmits the RCU-Link and extends the CEX-Bus and RCU-Link cable length up to 200 m. The number of CEX-Bus interfaces is limited to 6 with each BC820. You need to provide the following cables at a suitable length (not included in the BC820K02 kit): RCU Control Link: Modular Jack, RJ45, shielded twisted pair crossover cable with all four pairs crossed: EIA/TIA-568 standard crossover T568A to T568B. Length: max 200m. RCU Data Link: The optical interconnection is compatible with LC Duplex optical connector interface conforming to ANSI TIA/EIA60-10 (FOCIS 10A). The type of optical cable is 50/125μm OM3 fiber. Length: max 200m. For more information about the cables see 3BSE036351-* Features and benefits Supports redundant communication interface units. Supports on-line replacement of the CPU. External power supply. Supports hot swap.
