DescriptionRed Lion GEM1 Series Gemini 1000 6-Digit Presettable Counters or Rte Indicators, Single Level.
OverviewThe Gemini is a two input, microprocessor-based device which offers the features and performance of a single (GEM 1000)/dual (GEM 2000) level preset counter or sample time, rate indicator. The 6-digit display features 0.56" LEDs with negative sign and overflow indicators. The internal precision is maintained to 9 digits. The 20 mA Current Loop Option (Gemini 2000 only) makes possible remote or computerized monitoring or control of the count, Presets and Scale Factor.Flexibility and usefulness are insured through user programmability. With simple front panel keystrokes and rear panel switch settings, any one of a number of configurations can be selected. Once the selection is made, all or part of the keyboard can be disabled to protect the settings and guarantee that no unwanted changes can occur during the measurements. All set-up data is stored in E2PROM, which will hold data for a minimum of 10 years without power.Whenever the power comes on, the Gemini performs a series of internal diagnostics to verify the integrity of the stored data. There is also a self-test mode and an ever-present “watchdog” timer to prevent processor lockup.The construction of the Gemini features a metal, die cast bezel for maximum durability with high quality appearance. The sealed front panel meets NEMA 4/IP65 specifications for washdown and/or dust. Electrical connections are made with removable, plug-in terminal strips at the rear of the unit. Clamp type pressure plate terminals accept stripped #14 AWG wire without lugs.As a counter, the Gemini can monitor bi-directional, unidirectional(totalizer), or quadrature signals. It can double or (with quadrature) even quadruple the resolution of the incoming signal. Counting modes also provide for anti-coincidence applications. Both channels of count information are monitored simultaneously, no counts are lost, and the final output can be chosen as the sum or difference of the two input channels.As a rate indicator, a variety of sampling times are available. Accurate to one hundredth of a percent, the sampling time can be set as 1, 2, 5, 10, 20, or 50 seconds. The preset level(s) can be selected to control an open collector output(s). The optional Gemini plug-in relay board makes it easy to field upgrade your Gemini to provide 5 amp, 240 VAC relay output(s). The output(s) are also programmable and can be set for terminate at the “other” output start, “other” output end, at reset or reset end, after time delay, or boundary...
