System 350

The Y350R is a rectified Class 2, 24 VAC power
supply module designed specific ally for use with
System 350™ Modular Control Systems.

As with all System 350 products, the Y350R is housed
in a compact NEMA 1, high-impact plastic enclosure.
The modular design provides eas y , plug-in
connections for quic k ins tallation and future
expandability.

The Y350R operates f r om 240 V A C or 120 V A C
power. A 24 VAC, Clas s 2, step-down trans former
brings the voltage to a level which the Syst em 350
modules will accept. There are no adjustment s for the
power module.

nstallation and Wir ing

I

The Y350R case has provis ions for mounting to a
standard 35 mm DIN r ail, or can be mounted using t he
four key slot m ounting holes located in the rear of the
case.

Mount System 350 modules in any convenient location
using either the DIN r ail m ounts or the mounting holes
located on the back of the control case. The
components are not pos ition sensitive, but should be
mounted so they can be eas ily wir ed and adjus ted.
