SJE Rhombus Model 32S

The Model 32S control panel from SJE Rhombus is designed to alternately control two three-phase pumps in industrial and commercial water and sewage systems using the DPC-4F Pump Control Four Float Controller for pump sequence, alternation, selection, lag pump delay time, and alarm. If a high-water alarm condition occurs, the high-water alarm float activates the audible/visual alarm system along with auxiliary contacts for remote alarm. Common applications include lift stations and pump chambers. Models are available with intrinsically safe relay for circuit extension into hazardous locations. It is UL/cUL Listed. 888-342-5753; www.sjerhombus.com

Jet Inc. Model 197

The Model 197 control panel from Jet Inc. monitors the operation of the Jet Inc. treatment system aerator and additional components. It can monitor single- or dual-aeration systems with selectable high- and low-amperage monitor settings. The panels have dedicated alarm and control circuits with separate power circuits for aeration devices. In addition to the aerator control circuits, the panel contains three auxiliary 120-volt output circuits for external device control relays. They include three low-voltage auxiliary input circuits selectable for N/O or N/C alarm inputs. An integrated pump power control relay is automatically disabled in an auxiliary device alarm condition. A signal array includes a power indicator LED and four equipment alarm indicator LEDs. 800-321-6960; www.jetincorp.com
