2 Channel 5A 24V DC Solid State Relay Module Arduino
Size: 55 * 33 * 22 (L * W * H)
Using high-quality solid-state relays 5A.
The input and output are using KF128-3.81 Terminal Block, wiring more convenient.
Use SS8050 1.5A high current transistor for switching transistor, quality is more stable.
DC +: positive power supply (by relay voltage power supply)
DC-: connect power negative
CH: Relay module signal to trigger the end (low to trigger effective)
NOTE: Power must be DC Voltage, voltage must be consistent with the relay voltage
