Description
Structural Features: 1. Use Hongfa relay, stable and reliable performance;2. Compatible with two input modes of positive control and negative control;3. Each channel has an LED action indicator for a more intuitive understanding of product performance;4. Each channel adopts optocoupler isolation to enhance anti-interference performance and isolation performance;5. At the same time, the power supply and the "IN" control terminal are independently controlled;6. The module adopts the standard "DIN" rail-type installation design, which is convenient and quick to install, firm and stable. Technical Parameters: 1. Trigger signal: DC5V / 12 / 24V (Optional)2. Each trigger signal current: 5mA3. Power supply voltage: DC5V / 12 / 24V4. Each coil current: 18.8mA5. Contact type: one normally open and one normally closed (single pole)6. Maximum load current of each contact: 10A7. Action time: below 12ms8. Reset time: less than 4ms9. Maximum switching frequency: 18000 times / hour10. Mechanical life: more than 20 million times11. Relay installation: plug-in type (No)12: Module installation method: DIN standard rail installationPositive control wiring introduction: 1. Power input terminal:VCC is connected to the positive voltage, GND is connected to the negative voltage, and S / S is connected to the negative voltageIN1, IN2 are connected to positive voltage control, IN1 controls KI terminal, IN2 controls K2 terminal2. Control device output:The output terminal is clearly marked with 234, 3 is a common point, 2 is normally open, and 4 is normally closed. K1, K2 means two relays work. Negative control wiring introduction: 1. Power input terminal:VCC is connected to the positive voltage, GND is connected to the negative voltage, and S / S is connected to the positive voltageIN1, IN2 are connected to negative voltage control, IN1 controls KI terminal, IN2 controls K2 terminal2. Control device output:The output terminal is clearly marked with 234, 3 is a common point, 2 is normally open, and 4 is normally closed. KI, K2 means two relays work.
