GE IC6P3CBL303 Genius I/O Master Network Interface Module

Configured for distributed I/O data exchange and network management in Genius I/O networks, the GE IC6P3CBL303 (IC6P3CBL303 Master Network Interface) provides direct physical/electrical execution. Communicating over a bus topology via the proprietary Genius LAN protocol at 153.6 kbps, the module interfaces host controllers with up to 32 remote Genius I/O blocks across a maximum segment length of 7,500 meters. Power is supplied via an external 24 VDC source drawing 300 mA current.

Hardware Specifications

Backplane Bus Communication Velocity & Network Integration

The IC6P3CBL303 maintains high backplane bus communication velocity by handling Genius LAN protocol packet assembly and node scanning locally, achieving a typical scan cycle time of 3 ms across up to 32 connected remote nodes. Local processing offloads peripheral bus traffic from the host controller CPU, allowing real-time I/O updates over 153.6 kbps bus segments up to 7,500 meters long. Front panel LED indicators provide instant hardware diagnostic feedback on network link integrity, while strict firmware flash compatibility ensures synchronized cyclic communication across all connected Genius blocks.

Frequently Asked Questions

Q: What network topologies and cable length limits are supported by the master network interface?

A: The module supports a daisy-chained bus topology operating on the proprietary Genius LAN protocol at 153.6 kbps, supporting up to 32 connected nodes and maximum segment lengths up to 7,500 meters.

Q: How is the physical interface connected and powered during field deployment?

A: The module connects to the network media through a female 15-pin D-sub connector and requires an external 24 VDC power supply connected to its designated terminal block, drawing 300 mA during standard operation.

Field Installation Guidelines

1. Snap the module securely onto a standard 35 mm DIN rail inside the enclosure cabinet.
2. Connect the Genius LAN bus cable assembly to the 15-pin female D-sub interface port, tightening connector hold-down screws to prevent vibration loosening.
3. Wire the external 24 VDC supply leads to the module power terminal block, observing correct DC polarity before energizing the circuit.
4. Verify overall segment wire length does not exceed 7,500 meters and ensure proper end-of-line termination resistors are enabled across the Genius LAN bus.
5. Connect cable shield drain wires to a single-point functional earth ground bus bar to protect 153.6 kbps signals against high-frequency noise interference.
