A1D1 (8-30V DC)

The EAPL A1D1 is a compact, high-precision On‑Delay Timer, engineered for DC-powered industrial control systems. Utilizing an 8–30 V DC input, it delivers reliable timing and automation in a DIN-sized form factor ideal for panel and rail mounting.

Key Specifications

Supply Voltage: 8 V DC to 30 V DC 

Function: On‑Delay timer — output relay activates only after the preset delay 

Time Range: Adjustable from 0.3 seconds to 30 minutes 

Output: Dual form‑C, 2 C/O relays for flexible control logic 

Contact Rating: Up to 5 A at 250 V AC or 30 V DC (resistive load) 

Mounting: DIN‑rail or screw‑mountable enclosure (~22.5 mm W × 75 mm H × 102 mm D) 

LED Indicators: Integrated LEDs show both power and relay/timing status 

Built-in Features: Includes HOLD/RESTART function for power‑fail resilience, programmable “Program Enable/Disable” for tamper prevention, and Auto/Manual operation mode

Applications
Optimized for use in industrial environments including:

AMF (Auto Mains Failure) control panels

HT/LT switchgear panels

Motor Control Centers (MCC)

Transformer and RTCC panels

Automation, control, and process panels requiring reliable delay functions 

Advantages Snapshot

• Wide DC input compatibility ensures versatility across low-voltage systems.

• Dual relay outputs allow for versatile control scenarios (e.g., cascading or redundant switching).

• Broad timing adjustability suits both quick operations and longer delays.

• Industrial-grade reliability through LED indicators, safety covers, and durability-focused design.

• Space-efficient profile fits neatly into panel systems, streamlining installation.
