Product Details:
Solid State Relay Module
Size: approx. 25 x 34 x 25mm, net weight: 13g
5v solid-state relay 240v 2a , the output resistance fuse is 240v 2a.
Input voltage: 5v dc (160ma)
Input voltage control signal: (0-1.5V low level, relay ON), (2.5-5V high level, relay OFF)
Quiescent current: 0MA
Trigger voltage: 0-1.5v
Trigger current: 2ma
Module interface:
The positive (DC + : connect power according to the relay voltage power supply)
DC - : connect power negative
CH: relay module (effective) low level trigger signal trigger end
High level and low level meaning:
High level refers to the trigger signal trigger terminal (IN) and negative between a power source
A forward voltage, usually with the power of the positive and trigger a client connection
Kind of trigger mode, when the trigger side has the positive voltage or trigger voltage, relay is off.
Low level trigger refers to signal triggering end between the cathode voltage and power
For OV, or trigger voltage lower than positive voltage,
Low enough to trigger voltage, relay, absorption is often will power
The negative connection way of a trigger and trigger the end, the relay is off.
