If inductive loads or stronger currents are switched
through, the gold plating on the relay contact surface will
be permanently damaged. The contact is then no longer
suitable for switching low-level signal circuits.
Contact material (relay contacts) AgNi or AgSnO and Au plated
Transistor output
Output
Floating transistor output, permanently shortcircuit-proof
Load current < 400 mA
