Physical Dimensions and Construction

This unit measures 15.0 cm in length and 7.5 cm in width. Its total height reaches 11.0 cm including DIN rail clip. 6GK1102-0AC00 weighs 0.56 kg for compact panel mounting. The metal housing provides robust protection and EMI shielding.

Moreover, the unit includes LED indicators for each active port. These LEDs show link status and data activity at a glance. Ventilation slots on the sides allow passive cooling during operation.

Port Configuration and Signal Distribution

Eight RJ45 ports connect to end devices like PLCs and HMIs. An internal active repeater regenerates the signal for each output. This design maintains signal integrity over cables up to 100 meters. All ports support auto-MDI/X for straight or crossover cables.

Power Supply and Diagnostics

A 3-pin terminal block accepts 24V DC input power. The unit draws only 6 W under full load conditions. A green LED indicates proper power supply status. Additionally, a fault relay contact signals loss of input signal.

Typical Application Scenarios

You can deploy 6GK1102-0AC00 in industrial Ethernet networks needing multiple device connections. It also works well for star topologies in control cabinets. This unit connects one automation device to eight field devices reliably. Its compact size fits into crowded electrical enclosures.
