Key Features

1. Enhanced Entry‑Level Kit: Same low‑cost concept as 41010 but with 140CPU11303 for better speed/performance

2. Pre‑Integrated Redundancy: All core components in one box, factory‑tested, ready to deploy

3. Fiber Synchronization: 10 Mbps duplex fiber, excellent noise immunity

4. Bumpless Switchover: <50 ms, no data loss

5. Discontinued: Replaced by newer Quantum hot standby solutions

Applications

• Cost‑sensitive critical processes needing better CPU performance than 41010

• Water/wastewater, light manufacturing, packaging, material handling

• Projects where budget is limited but higher CPU power is required

Differences

• 140CHS41010: Level One, 140CPU11302, basic entry kit

• 140CHS41020: Level Two, 140CPU11303, enhanced entry kit (faster CPU)

• 140CHS11000/11100: Standalone hot standby modules (no CPUs/PS/backplanes)

• 140CHS21000/21000C: High‑end hot standby kits (wider temp range, optional conformal coating)

• 140CHS32000: Coaxial splitter kit (copper instead of fiber)
