Display panel delivers two separate parameters
A new display is designed for applications that require two parameters to be visualized simultaneously. For example, the device can read a flow rate through a pipeline while totalizing the gallons, or indicate the temperature of an oven while also displaying the setpoint value.
Red Lion Controls, Inc. announces the PAX2A Dual Line Display Meter, which can display input, total, minimum, maximum, or setpoints on a 0.7-in. high, six-digit main LCD display.
The main display offers three programmable colors — red, orange, and green — and color change can be tied to the setpoints to give operators a visual display of changing conditions in the application. Updates can be made up to 160 times per second. The panel meter also features a second display line: a 0.35-inch high, nine-digit green LCD display that can also be programmed for any of the above parameters, plus a three-digit programmable custom unit indicator is also available.
The dual line display meter provides universal functionality, and accepts as input dc current, dc voltage, process signal, thermocouple, and RTD temperature sensor inputs. PAX2A also supports universal power input, from 50 to 250 Vac or 21.6 to 250 Vdc. Built-in Modbus communications in addition to field installable option cards (RS232, RS485, DeviceNet, and Profibus) allow communications across a multitude of protocols. It also has a built-in USB port for simple connectivity.
