L4437A 32-Channel General Purpose Switch Hardware Description

The L4437A general- purpose switch provides independent control of:

•Twenty- eight Form C (DPST) latching relays rated at 1 A

•Four Form A (SPST) latching relays rated at 5 A. You can set the power- failure state for these 5 A relays. See page 128 and page 129.

	N O TE	A temperature sensor on these modules triggers system interrupts
	N O TE	when high-carry current-induced heat on the modules reaches a

		threshold of 70 oC.
