Hardware Specifications

Deterministic Industrial Control & Bus Execution

The 07 KT 97 processor relies on optimized backplane bus communication velocity and integrated memory management to maintain continuous cycle processing. Onboard firmware flash compatibility ensures synchronized operational execution between standard I/O processing tasks and high-speed network protocols over Ethernet TCP/IP. The internal memory map separates user code execution (480 kB) from variable data logging (256 kB), preserving application state determinism across dynamic loop execution cycles.

Frequently Asked Questions

Q: How are Pt100 RTD sensor inputs configured on the integrated analog input channels?

A: Analog input channels accept 2-wire or 3-wire Pt100 configurations directly by assigning internal hardware jumper positions and setting register parameters in the system software to match the target signal range.

Q: What power source requirements apply to the 07 KT 97 base module?

A: The module requires a regulated external 24 VDC power supply operating within -15% to +20% tolerance to ensure proper CPU execution and analog conversion reference stability.

Field Installation Guidelines

1. Mount the 07 KT 97 unit vertically onto standard 35 mm DIN rails inside a grounded metallic enclosure rated for industrial environments.
2. Ensure at least 50 mm of vertical clearance above and below the housing for uninhibited thermal convection.
3. Terminate all analog signal cabling using twisted-shielded pair conductors, connecting the cable shield directly to functional earth (FE) near the terminal strip.
4. Keep 24 VDC logic and high-voltage power wiring in separate wire ducts to prevent electromagnetic cross-talk into sensitive analog channels.
