Maintenance, Test & Measurement, Calibration
Red Lion Controls is offering its PAXDP dual process input meter, an innovative two-in-one process control solution that lets users monitor, scale, and display two independent input sources, perform a high-speed math function on the input values, and displays the resulting value.
The PAXDP can be set up to display input values from both signal sources, calculate, and display a resultant value based upon the two input values. With optional plug-in cards, the meter can be equipped to generate desired outputs including alarm triggering, retransmission of analog output, or data to comms via a host of industrial communication protocols.
"The PAXDP adds sophisticated monitoring of tolerances and ranges to many process applications, including displaying and calculating of input/output and before/after differentials in pressure, voltage, flow, dimension and levels," said Jeff Thornton, product manager. "By adding a second input to our industry-standard PAX metering platform, PAXDP offers a flexible means of monitoring, comparing and calculating from two separate input sources."
Among the integrated maths functions in the PAXDP are addition, subtraction, multiplication, division and complex calculations incorporating a defined constant value. Maths functions are performed at high speeds and results can be calculated at user-selectable rates from five to 105 updates per second. The meter incorporates 16-point scaling for nonlinear processes and a 9-digit totaliser (integrator) with batching capabilities.
The 1/8 DIN PAXDP meter is available in both AC and DC models that accept two 4 to 20 mA or 0 to 10 V d.c. input signals. Features include a NEMA 4X/IP65 sealed front bezel, a 5-digit sunlight-readable 0,56" LED display with variable intensity, Flash programmable software upgrades, and programmable function keys/user inputs. Available for programming the PAXDP is the robust, intuitive Crimson 2 software - a flexible and powerful programming language that facilitates communication across a broad range of industrial controls and devices.
A series of optional drop-in cards expand the PAXDP's output capabilities. Four setpoint output cards are available including dual FORM-C relays, quad FORM-A relays, quad sinking or quad sourcing. A retransmitted analog output card offering 4 to 20 mA or 0 to 10 V d.c. is also available. The PAXDP offers the Modbus communication protocol standard; additional communication/bus card offerings include RS232, RS485, DeviceNet and ProfiBus-DP. The company offers a free brochure detailing typical applications for the PAXDP. More information can also be found at the company's website www.redlion.net/panelmeters. Red Lion Controls is a leading manufacturer of industrial control solutions worldwide. Products include digital/analog control, monitoring and panel meters, PID control, human-machine interface panels, and signal conditioning.
