Подключение

Подключение пинов Out

7i37 не яаляется источником питания, она переключает сигнал от внешнего источника питания. Каждый выход это изолированный DC ключ с максимальной нагрузкой 1А при 48В.

Например, если вы хотите подключить 24В реле, то вам нужно подключить положительный контакт обмотки релле к +24В источника питания, отрицательный контакт к +OBIT 7i37, -OBIT 7i37 к отрицательному контакту источника питания.


For example, If you had a 24VDC relay, normally you would wire the positive relay coil
terminal to a +24VDC power source, wire the negative coil terminal to the + 7I37 output
and connect the - 7I37 output to your power sources Negative or common terminal. 

Since each of the output switches of the 7I37 are isolated, other connections are possible, 
For example its possible to drive ground referred loads (one side of load is grounded) by 
connecting the 7I37's + output to the positive power source and connecting the 7I37's - output to the load

В случае с 7i37com минус подключается к нагрузке, а +24В источника питания к V+ POWER TB4. Также VC (VClamp) нужно подключить к -источника питания.

CLAMP DIODES
The 7I37COM provides clamp diodes to limit voltage spikes when driving inductive
loads. These clamp diodes connect to TB4 pins 1 and 2 (VC). VC must be returned to
control power negative (commonly ground) to utilize the clamp diodes. The VC
connection to control power negative (or ground) should be wired with a separate wire and
should not share the input common connection to control negative. This is because the VC
line could have transient currents of up to 8A if 8 1A inductive loads were turned off at
once.
