The IC660BBD021 is a high-performance, 16-point configurable discrete I/O block for the Genius I/O distributed network. Each channel can be independently configured as input or output, supporting both 24 VDC and 48 VDC systems. It is a sink-type block with robust diagnostics, enabling decentralized, high-speed control. Its reliability and advanced fault detection make it a core component in legacy PLC applications across manufacturing, automotive, and water treatment industries.

Configurable I/O: Each of the 16 channels can be individually set as input or output.
Advanced Diagnostics: Monitors open circuits, switch failures, and over-temperature events at the individual channel level.
Non-Volatile Memory: Preserves configuration settings during power loss.
High-Speed Scanning: Suitable for fast automation cycles and real-time control.
Legacy Integration: Compatible with modern RX3i controllers via a Genius Bus Controller (GBC), enabling gradual system upgrades.
How is the IC660BBD021 configured?
Using a Genius Hand-Held Monitor (HHM) or PLC software (e.g., Proficy Machine Edition). Each point can be set as input or output with diagnostic thresholds.
Sink vs. Source blocks – what’s the difference?
As a Sink block, the module provides the path to ground for the load. It is compatible with field devices that source positive voltage.
Can it be used with modern RX3i controllers?
Yes, with a Genius Bus Controller, allowing legacy I/O to integrate into RX3i systems, supporting a cost-effective migration path.
