AT8PMN AUTONICS Power OFF Delay Analog Timer
The AT8PMN AUTONICS (AT8PMN Series) is a compact, 8-pin plug-in analog timer specifically engineered for power OFF delay control applications in industrial automation panels and motor control circuits. Designed to keep relay contacts energized for a user-set duration after main control power is interrupted or lost, the AT8PMN AUTONICS ensures safe equipment shutdown, delayed fan extraction, and emergency cycle completion.
Featuring a front-panel analog dial with clear time range selection, the AT8PMN AUTONICS delivers high repeat accuracy and simple adjustment without complex digital programming. Housed in a standard DIN $48 \times 48\text{ mm}$ enclosure with universal 8-pin socket connectivity, it installs effortlessly into control cabinets, machinery panels, and marine electrical enclosures.
Key Features of the AT8PMN AUTONICS
-
Power OFF Delay Operation: Maintains output contact actuation for a specified duration following control power removal.
-
Front-Panel Analog Dial: Direct rotary dial setting for easy time delay selection and visual countdown monitoring.
-
Flexible Voltage & Range Options: Available in various power supply configurations (100–120VAC, 200–240VAC, 24VAC/VDC) and time range variants (seconds to minutes).
-
Standard 8-Pin Socket Mounting: Industry-standard 8-pin round plug connection compatible with PS-08 and PG-08 mounting sockets for panel or DIN-rail installation.
-
Reliable Relay Output: Equipped with DPDT (2c) or SPDT time-limit contacts rated for 250VAC 3A resistive loads.
-
Status LED Indicators: Dedicated LED lights display power input state and output relay status for rapid visual troubleshooting.
Primary Applications
-
Emergency Motor & Pump Protection: Delayed shutdown of lube pumps, cooling fans, and ventilation blowers after main power interruption
-
Industrial Process Automation: Controlling post-cycle purging, heating element cooldowns, and conveyor clearance routines
-
Marine & Machinery Panels: Providing timed off-delay interlocks on generator control systems and shipboard machinery control cabinets
