The Model 197 control panel from Jet Inc. monitors operation of the Jet 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. The panels 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 additional equipment alarm indicator LEDs. The integrated alarm buzzer has an output for an optional remote-mounted audible alarm. 800/321-6960; www.jetincorp.com.
