This document is an introduction to the CHRONOS 2 series multi-function timers, including the functions, features, dimensions, specifications and other information of the timers.
The leaflet describes Crouzet's Chronos 2 analogue and digital timers, available for DIN‑rail, front‑panel, and plug‑in mounting. It lists the various timer functions (A‑At, Di‑D, Li‑L, etc.) and shows the ordering guide with part numbers for each voltage and configuration.
Technical data include timing ranges from 1 s to 100 h, multi‑voltage power supplies (12 V‑240 V AC/DC), relay output ratings of 2000 VA/80 W, and compliance with IEC, EN, and CE standards. Protection classes, temperature limits, and life expectancy of the relays are also provided.

The Chronos 2 timers offer seven timing ranges from 1 second up to 100 hours.
They are multi‑voltage devices that can be powered from 12 V to 240 V AC or DC.
Each timer’s relay is rated at 2000 VA (80 W).
The terminal block is IP20, the casing is IP40, and the front face (except Tk2R1) is IP50.
