B1DCA-X

B1DCA-X – Product Description

• A cyclic adjustable ON/OFF timer from EAPL's B-Series (X-Version).

• Enables independent adjustment of ON and OFF intervals.

• Designed for DIN-rail or screw‑mount panel installation in an industrial setting.

• Includes manual/auto operation control and tamper‑proof programming features.

Key Specifications

• Function: Cyclic ON/OFF timer, independently adjustable ON and OFF times. 

• Supply Voltage (X-Version): 24 VAC to 240 VAC and 24 VDC to 220 VDC. 

• Time Range: 0.6 seconds to 60 minutes. 

• Output: 2 change‑over (C/O) relay contacts, rated 5 A at 250 VAC / 28 VDC resistive load. Power Consumption: Approximately 5 VA (AC) or 1 W (DC). 

• Range Selection: Preset switches for ranges such as 6 s, 18 s, 36 s, 60 s, 3 m, 6 m, 30 m, 60 m. 

• Timing Accuracy:

  • Repeat accuracy: ±1% ± 100 ms.

  • Recovery time: Min 100 ms.

  • Environmental Conditions:

  • Temperature: –10 °C to +55 °C operating; –25 °C to +80 °C storage.

  • Humidity: Up to 85% RH @ 40 °C.

  • Service Life:

  • Mechanical: ≥10⁶ operations (no load).

  • Electrical: ≥10⁵ operations (full load), operation up to ~1800 cycles/hour. Insulation & Dielectric Strength:

  • Insulation resistance: >100 MΩ at 500 V DC.

  • Dielectric withstand: 2.5 kV AC across parts; 1.5 kV AC between contacts & control; 1 kV AC across non‑continuous relay contacts.

  • Connections & Dimensions: Screw-type terminals with self‑lifting clamps; size: approximately 45 × 75 × 116 mm (W × H × D).

Applications

• Ideal for systems needing cyclic on/off control, such as lubrication systems, diesel generator (DG) sets, pump panels, etc. 

• Suited for integration into Motor Control Centers (MCC panels) and general automation panels requiring timed relay cycles.

• Manual mode options allow direct user control over switching when needed. 

Summary

• The B1DCA-X is a robust cyclic ON/OFF timer offering precise, independent ON and OFF timing with a broad range (0.6 s to 60 min).

• Equipped with dual relay outputs, wide voltage compatibility, and manual override/tamper-proof functionality.

• Built for reliability: compact, rugged, with high insulation and long operational life—ideal for automation, lubrication cycles, DG sets, and MCC applications.
