Description
LBA120 comprises two independent 250V, 170mA,
20 ? solid state relays: one single-pole, normally
open (1-Form-A) relay and one single-pole, normally
closed (1-Form-B) relay.
Features
? 3750V rms Input/Output Isolation
? Low Drive Power Requirements (TTL/CMOS
Compatible)
? High Reliability
? Arc-Free With No Snubbing Circuits
? FCC Compatible
? VDE Compatible
? No EMI/RFI Generation
? Small 8-Pin Package
Featuring low on-resistance combined with enhanced
peak load current handling capabilities, LBA120
is designed to provide an ideal solution where a
complementary Form-A/Form-B relay pair is required.
