Supported Applications
The Omega DPT35 series is a dual pulse timer and totalizer designed for use with meters and flow sensors that produce a pulse signal. The product overview identifies typical applications in water treatment and chemical dosing, specifically within cooling towers and boilers.
Operating Conditions & Performance
The DPT35 series operates under ambient temperatures ranging from 32° - 130° F (0° - 55° C). The device accepts a maximum input frequency of 1000 Hz. It features independent accumulators with an accumulator range of 1 - 9999 pulses and a timer range of 1 - 9999 seconds.
Configuration Options
The series is housed in a 5" x 7" polycarbonate enclosure. Electrical specifications include a power supply requirement of 115 Vac, sensor excitation voltage of 12 Vdc, and two outputs rated at 115 Vac.
• Power & Protection: Requires 115 Vac; includes a 3AG-10A-SB Fuse for electrical connection protection.
• Outputs: Provides dual timed outputs with relay contact ratings of 5 A resistive @ 115 Vac, or 1/4 HP.
• Housing Material: Constructed from polycarbonate in a wall-mount configuration measuring 5" x 7" overall dimensions.
Key Product Differences
The DPT35 series functions as either a single or dual timer depending on whether one or both of its independent accumulators and timed outputs are utilized. The available variants include the standard model (DPT35) and an alternate configuration (DPT35S), both sharing the same core specifications for power, output ratings, and operating temperature.
