Ang serye GRL8-01/02 mao ang isang intelligent control relay nga gihimo pinaagi sa liquid level monitoring, gamiton ang isolated power supply technology ug modular structure. Ang iyang compact 18mm width body nag-support sa 35mm standard card rail installation, angay sa mga automation control scenarios alang sa iba't ibang liquid storage ug transportation systems.
Mga katangian sa produktong GRL8-01/02 series liquid level control relay:
1. Dual mode flexible configuration
Ang Type 01 nag-support sa 2-pole liquid level control
Ang Type 02 nag-support sa 2-pole o 1-pole liquid level control
2. Programmable working mode
Libreng pagpili sa drainage mode (triggered by high liquid level) o water supply mode (triggered by low liquid level) pinaagi sa dip switch
3. Precision parameter adjustment
Sensitivity 5-100k Ω continuously adjustable, angay sa liquids nga may lain-laing conductivities
Ang action delay mahimong iset ania 0.1s-10s, efektibong pag-suppress sa interference gikan sa liquid level fluctuations
4. Wide voltage compatible design
Nag-support sa AC/DC 24~240V wide input, ang isolated power supply nag-enhance sa system safety
5. Visual state management
Duha ka kulay LED indicator lights display real-time power supply status ug relay action signals
6. Industrial grade compact structure
35mm rail installation sumala sa DIN EN 60715 standard, 18mm ultra-thin width saves control cabinet space
Mga advantage sa GRL8-01/02 series liquid level control relay products:
1. Multi purpose: Isang device lang ang compatible sa water supply ug drainage modes, nag-reduce sa variety of spare parts
2. Anti interference design: ang adjustable delay function efektibo sa pag-filter sa false signals ug nag-improve sa action reliability
3. Strong compatibility: wide voltage input+wide impedance range angkop sa mainstream liquid level sensors worldwide
4. Convenient maintenance: Modular plug-in design supports quick on-site replacement, LED dual indication nag-reduce sa difficulty of fault diagnosis
5. Security Enhancement: Ang isolated power supply design nag-prevent sa induced electrical interference ug compliant sa industrial control safety standards
