Kit Contents

• 2 × Splitter boxes (MA0186100)

• 4 × Line impedances (520720000)

• Mounting hardware

• Installation manual

Key Features

1. Copper‑Based Redundancy: Uses coaxial cable instead of fiber for CPU sync

2. High‑Frequency Performance: 0–100 MHz bandwidth, low insertion loss

3. Noise Immunity: BNC/coax design resists EMI/RFI in harsh environments

4. Bumpless Switchover: Works with Quantum hot‑standby CPUs for fast failover

5. Easy Installation: DIN rail/panel mount, pre‑configured splitters

Applications

• Quantum redundant systems where fiber is unavailable or not preferred

• Industrial environments with high electrical noise (EMI/RFI)

• Retrofits of older coaxial‑based redundant PLC systems

Differences from Fiber Kits

• 140CHS11000/21000: Fiber‑optic sync (10 Mbps, 3 m cable)

• 140CHS32000: Coaxial sync (BNC, 50Ω trunk cable, high frequency)
