R353/S353 Series: Temperature Stage Modules
Description
The System 350™ R353/S353 Modular Electronic Sequencer is designed to provide multi-stage control in HVAC and refrigeration applications. The R353 Signal Input Module accepts input signals of 0 to 10 VDC, 0 to 20 mA, or 135 to 10k ohm slidewire potentiometer to drive up to ten S353 modules. The S353 Stage Modules contain a SPDT relay with an LED indicator of relay status. The sequencer’s modular design provides easy, plug-together connections for quick installation and future expandability. The R353/S353 may be used as a replacement for the Penn R23 Actrol™ Sequencer.
