XINGYHENG 10PCS One Channel Relay Module 12V Low Level Trigger Relay Expansion Plate Load Controlled Relay Switch Module for Industrial Automation Process

Features and benefits: Product introduction: 1. This module conforms to international safety standards, and there is an isolation slot between the control area and the load area; 2. With power supply and relay action indication, suction and bright, not bright; 3. When there is a signal at the signal input end, the common end and the normal beginning will be switched on; 5. Can be used as a MCU development board module, can be used as home appliances control; 6. Control dc or ac signal, can control 220V ac load; 7. There is a normally open and a normally closed contact; 8.Blue KF301 terminal is more convenient to connect to the control line. Electrical parameters: The module Operating voltage: 12V Static current: 5.5ma Static current: 42mA8. Trigger voltage: 0-4v8. Trigger current: 3mA8. Working temperature: -20 ° C ~ +85 ° C Indicator light: LED Installation: Screw fixation Size: 58mm/2.3’’ ×45mm/1.77’’ ×26mm/1’’(Length×Wide × Height) Weight: about 0.1KG Package including: 10 x relay module Note: High level trigger refers to the trigger mode with voltage between the signal input terminal and the ground, which can be understood as a short-circuit trigger mode between the signal input terminal and the VCC positive pole. Low-level trigger means that the voltage between the signal input end and the ground is triggered by OV, which can be understood as a short circuit trigger between the signal input end and GND negative pole
