GR8 Intermediate Relay AC/DC 12V,24V,48V,110V,AC230V

The GR8 series Intermediate Relay is an intermediate relay designed to enhance load capacity or multiply the contacts of existing equipment. It supports a wide range of voltages (optional), including AC/DC 12V, 24V, 48V, 110V, and AC 230V. The GR8-316 model is compatible with three-phase circuits. Relay status is indicated by an LED, and its 1-module design allows for DIN rail mounting. Ideal for industrial control and automation systems, it provides reliable signal amplification and isolation functions.

Description

GR8 Intermediate Relay Product Features:

  • Voltage Range (Optional): AC/DC 12V, 24V, 48V, 110V, and AC 230V, offering compatibility with various power supplies for flexible application in diverse electrical environments.
  • Multiple Models Available: Includes GR8-116 (1×SPDT 16A), GR8-208 (2×SPDT 8A), GR8-308 (3×SPDT 8A), and GR8-316 (3×SPDT 16A), catering to different control needs.
  • Load Capacity: Maximum current of 16A/AC1, switching voltage of 250VAC/24VDC, and minimum breaking capacity of 500mW (DC), capable of handling larger load outputs and offering stacking capacity to replace small contactors.
  • Control Flexibility: Enables specific control objectives by changing contact states, enhancing system adaptability; can be connected in series with the original contactor coil, using normally closed or normally open contacts to control corresponding components, expanding contact quantity and capacity.

Application Scenarios:

  • Enhancing load capacity
  • Increasing the number of contact groups
  • Suitable for automation control systems, industrial equipment signal isolation, and amplification.
