The meaning of high and low level:
INx stands for the contacts including IN1, IN2, IN3 and other pins in the following part.
Triggered at high level means a forward voltage exists between signal triggering terminal (INx) and negative supply voltage. It generally connects positive supply voltage and triggering terminal together. When triggering terminal has positive supply voltage or reaches triggering voltage, the relay will pull in.
While triggered at low level means the voltage between the signal triggering terminal (INx) and negative supply voltage is 0V, or the voltage at the triggering terminal is lower than positive supply voltage. If it lowers to a triggering voltage, the relay will pull in. It generally connects negative supply voltage and triggering terminal together.
Output:
Each submodular of the relay has one NC(nomalclose), one NO(nomalopen) and one COM(Common). So there are 8 NC, 8NO and 8 COM of the channel relay in total. NC stands for the normal close port contact and the state without power; No stands for the normal open port contact and the state with power. COM means the common port. You can choose NC port or NO port according to whether power or not.
