Zone 1DATCON DT9100 Digital Clock

The DATCON DT9100 is an ATEX-certified intrinsically safe digital clock specifically engineered for dependable, precise time synchronization in Zone 1 and Zone 2 hazardous areas. Designed for harsh processing environments across oil & gas, chemical production, and offshore platforms, this industrial unit provides unambiguous local visual timekeeping while meeting strict explosive-atmosphere safety mandates.

Equipped with a high-accuracy crystal oscillator delivering typical accuracy within ±1 minute per year, the DT9100 features a large 4-digit liquid crystal display (25.4 mm character height) visible across active work floors. Field configuration is simplified with three front-panel push buttons protected by a two-level password system, offering flexible synchronization via a 4–20 mA current loop, an external IS digital input, or local manual control.

Key Features:

✅ ATEX Certificate  II (1) 2G Ex ia IIC T5 / T6 Gb for Zone 1 and Zone 2 hazardous areas
✅ High-precision crystal oscillator with typically less than ±1 minute error per year
✅ Large 4-digit LCD with 25.4 mm character height in HH: MM format
✅ Available as field-mount housing (IP65) or standard DIN panel-mount (IP65 front / IP30 rear)
✅ Flexible power options: Intrinsically Safe 4.5 V battery pack or 4–20 mA loop-powered
✅ Internal time backup retains accurate time for up to 60 minutes during power interruption or battery swap
✅ Two isolated digital outputs for automated alarm and status signaling
✅ Three selectable synchronization modes (local push-button, IS digital input, or 4–20 mA current loop control)
✅ Two-level password security against unauthorized parameter adjustment

FAQs:

How long does the internal battery last on the battery-powered version?
The internal intrinsically safe battery pack (DT9100 B / DT9102 B) powers the unit continuously for at least three years, with minimal shelf-life loss (approx. 1% per year at 20°C).

Will the clock lose time during a battery replacement or loop shutdown?
No. Both models incorporate an internal backup system that retains time and configuration data for up to 60 minutes when disconnected from power.

How can the clock be synchronized remotely?
Battery-operated models support synchronization via an intrinsically safe digital input, while loop-powered models synchronize using the 4–20 mA current loop (4–10 mA standard operation, 14–20 mA synchronization signal).

Can unauthorized operators change the time or settings in the field?
No. The front push-button menu system is secured by a two-level password to prevent unauthorized adjustments.
