34937A 32-Channel GP Switch Module

34937A 32-Channel GP Switch Module

The 34937A general- purpose switch module provides independent control of:

•Twenty- eight Form C (SPDT) 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 “Hardware Power- Fail Jumper” on page 2).

N O T E	A temperature sensor on these modules triggers system interrupts
	when high-carry current-induced heat on the modules reaches a
	threshold of 70 oC. See description of the “HOT” annunciator on
	page 2.
