IDEC SmartRelay with transistor outputs
ou can identify IDEC SmartRelay versions with transistor outputs by the fact that the letter R is
missing from their type name. The outputs are short circuit-proof and overload-proof. An auxiliary
load voltage supply is not necessary, because IDEC SmartRelay supplies the load voltage.
Re uirements for transistor outputs
The load connected to IDEC SmartRelay must have the following characteristics:
The maximum switched current is 0.3 A per output.
Connecting
Connect the load to an IDEC SmartRelay with transistor outputs as shown below:
FL1F- 2BM2
The illustration below shows an example of how to connect the voltage or current load.
