B1DCA-T

B1DCA-T – Product Description

• The B1DCA-T is a cyclic adjustable ON/OFF timer from EAPL’s B-Series.

• Provides independent adjustment of ON and OFF times with multiple selectable ranges.

• Equipped with Hold/Restart functions for flexible operation.

• Compact DIN-rail or panel-mountable design with user-friendly rotary knobs and selector switches.

Key Specifications

• Function: Cyclic ON/OFF timer with adjustable ON and OFF intervals.

• Supply Voltage: Wide operating range (AC and DC, typically 24 V to 240 V AC and 24 V to 220 V DC for X-version models).

• Time Range: 0.6 seconds to 60 minutes with selectable ranges via switches.

• 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: Multiple ranges (e.g., seconds to minutes) selectable using the front panel.

• Accuracy:

  • Setting accuracy: ±10% of full scale ±100 ms.

  • Repeat accuracy: ±1% ±100 ms.

  • Recovery time: Minimum 100 ms.
