Hardware Specifications

Industrial Control and Ethernet Interface

The 07KT98 provides an RJ45 network connection with a specified data rate of 100 Mbps. The interface supports half-duplex and full-duplex operation with automatic negotiation and IEEE 802.3 compliance.

Network status is indicated through link, activity, and collision LEDs. The stated diagnostics include link loss detection and cable fault detection. For industrial control installations, Ethernet cabling should be routed separately from high-voltage and high-current conductors where practical to reduce electromagnetic interference.

The unit provides 24 digital inputs rated for 24 VDC operation. The specified 24 VDC output voltage and 0.5 A output current should be evaluated against the connected load and the complete controller power distribution arrangement.
