DH48J TIMER RELAY COUNTER

Description

The DH48J is a multifunction digital timer relay and preset counter used in industrial automation systems. It combines time-delay control and counting functions in a single compact unit, making it suitable for process automation, machinery control, production line monitoring, and sequential switching applications.

It can operate as a time relay (ON-delay, interval, cyclic timing) or as a counter relay (preset counting with output trigger) depending on configuration.

KEY FEATURES

• Digital timer relay with built-in counter function
• Time delay and preset counting modes in one unit
• High-precision timing with stable quartz-based control
• LED digital display for clear time/count indication
• Multiple timing ranges (seconds, minutes, hours depending on model)
• Supports ON-delay, OFF-delay, interval, and cyclic timing modes
• Preset counter function for production and cycle control
• SPDT relay output for flexible control wiring
• High switching capacity suitable for industrial loads
• External start, pause, and reset control input support
• Compact 48×48 mm panel mounting design
• Memory retention in case of power failure (model dependent)
• Widely used in automation and control systems
