Working Principle

1. AC/DC universal supply voltage input powers internal microprocessor timing control circuit and quartz crystal oscillator;
2. Operator sets timing function mode and target time value via front panel adjustment buttons, parameter stored in non-volatile memory without power loss data clearing;
3. After receiving trigger signal (power-on or external pulse trigger), microprocessor starts real-time countdown timing via high-precision crystal oscillator reference clock;
4. LED digital display synchronously outputs real-time remaining timing value for on-site visual monitoring;
5. When countdown reaches zero setpoint, internal SPDT relay coil energizes/de-energizes to switch contact open/closed state, output timing completion signal to downstream control components;
6. Internal isolation circuit separates power supply loop and load contact loop to prevent load inductive back EMF damaging timing core chip.

Function Features

• Six standard industrial timing logic modes configurable for diverse sequential control applications
• 0.01 second to 999 hour ultra-wide adjustable timing range, covers micro short delay and long production cycle timing demands
• Non-volatile memory retains all set timing parameters after complete power cut, no repeated re-setting after power recovery
• Universal 24–240 V AC/DC dual compatible power supply, compatible with all mainstream industrial control cabinet power distribution systems
• Visible LED real-time countdown display for direct on-site timing state judgment without measuring instruments
• Built-in inductive load freewheeling absorption circuit to suppress solenoid valve/contactor back EMF interference
• Anti-vibration timing algorithm maintains stable timing precision under continuous cabinet vibration environment

Performance Advantages

1. Single unit supports six timing function modes, reduces spare part inventory quantity compared to single-function analog timers;
2. ±0.01% ultra-high timing precision eliminates sequential control timing deviation causing equipment operation failure;
3. Wide universal voltage design avoids model selection errors for mixed AC/DC control cabinet power supply environments;
4. Narrow single DIN module structure maximizes cabinet space utilization for multi-loop timing control systems;
5. Non-volatile memory eliminates parameter reset after power outage, reduces on-site commissioning workload;
6. Silver alloy relay contacts achieve long electrical service life under frequent inductive load switching conditions.

Applicable Industries

Automated assembly line sequential control, packaging machine conveyor delay logic, motor star-delta soft startup control, hydraulic/pneumatic cylinder action delay timing, ventilation fan delay shutdown control, alarm signal delay output, boiler auxiliary equipment sequential startup timing, elevator auxiliary timing interlock logic.

Installation Requirements

1. Mount unit vertically on standard 35 mm DIN rail inside sealed electrical cabinet, no horizontal or inverted installation;
2. Input power wiring and load output wiring separated into independent terminal zones, avoid mixed wiring crosstalk interference;
3. Wire terminals fully inserted into clamp screw base, no exposed copper wire outside terminal insulation;
4. Cabinet internal operating temperature must not exceed +60°C; install cooling fan for high heat load multi-component cabinet layout;
5. Inductive loads (contactors, solenoid valves) must be equipped with external freewheeling diodes or surge suppressors parallel to load coil;
6. Maintain minimum 10 mm vertical clearance between adjacent timer relays for heat dissipation.

Usage Precautions

• Forbid installation outside closed electrical cabinet; open environment dust accumulation enters terminal gaps and causes short-circuit fault;
• Do not apply input voltage exceeding 240 V AC/DC; overvoltage destroys internal power supply circuit and timing microchip;
• Avoid continuous long-term operation at ambient temperature above +60°C; high temperature causes crystal oscillator drift and timing accuracy decline;
• Do not connect load current exceeding 8 A resistive / 3 A inductive to relay contacts; overload ablates silver contact alloy and disables switching function;
• Strong electromagnetic field (within 0.5 m of large contactors/inverters) must add signal shielding wiring to prevent timing value jump;
• Clean front panel button area only with dry lint-free cloth; liquid cleaning agent penetrates button gaps and causes internal circuit short circuit.
