6.2 Relay switching capacity
• Switch state ON: I
a
≤ 250 mA; switch state OFF: I
a
≤1 mA
• Switch cycles: >10,000,000
• Voltage drop PNP: ≤2 V
• Overload protection: Automatic load testing of switching current;
– Max. capacitance load: 14 μF at max. supply voltage (without resistive load)
– Max. cycle duration: 0.5 s; min. t
on
: 4 ms
– Periodic disconnection from protective circuit in the event of overcurrent (f = 2 Hz) and
