Key Features

1. Low‑Cost Redundancy: Entry‑level “Level One” package, lower price than CHS21000 series

2. Pre‑Integrated: All core redundant components in one kit, ready to deploy

3. Fiber Synchronization: Same 10 Mbps fiber as CHS11000 for noise immunity

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

5. Discontinued: Obsolete since May 2015; replaced by higher‑level Quantum hot standby kits

Applications

• Cost‑sensitive critical processes requiring redundancy

• Small‑to‑mid size plants: water/wastewater, light manufacturing, building automation

• Projects where budget is limited but zero downtime is mandatory

Differences

• 140CHS41010: Level One / Low Cost Kit (pre‑assembled, basic components, 0–40 °C, discontinued)

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

• 140CHS21000/21000C: High‑end hot standby kits (higher specs, wider temp range, conformal coated option)

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