Switched DC
• Output 1 and 2, 30 mA dc
maximum supply current not to
exceed 40 mA combined when
both outputs are used
• Short circuit limited to <50 mA
• 22 to 32V

• Use dc- and dc+ to drive exter-
nal solid-state relay.
• DIN-A-MITE compatible
Open Collector (Output 1 only)
• 100 mA maximum output cur-
rent sink
• 30V
Î
(dc) maximum supply
voltage
• Any switched dc output can use
the common terminal.
• Use an external class 2 or *SELV
power supply to control a dc
load, with the load positive to
the positive of the power sup-
ply, the load negative to the
open collector and common to
the power supply negative.
