Signal Conditioner has digitally stable circuit.

Press Release Summary:

High-density, DIN rail-mounted Model WV418 accepts RTD inputs and provides analog output proportional to input signal. It is field configurable via DIP switches for 2/3/4 wires, Pt100 RTDs of either alphas of 0.00385/0.00392, and copper Cu10 RTDs. Analog outputs include 0-10 Vdc and 0-20 mA, configurable for 95% of range. TouchCAL(TM) technology replaces mechanical/thermal variability of potentiometers and enables 100% adjustment of setpoints and deadbands.

Eurotherm, Action Instruments Announces New, Field Configurable, RTD Input Signal Conditioner with TouchCAL(TM) Technology; WV Series Model WV418

SAN DIEGO, CA - Eurotherm Action Instruments announces the immediate availability of the new WV Series, Model WV418, RTD Input Signal Conditioner with TouchCAL(TM) technology. This high density, field configurable, DIN rail mount device accepts RTD inputs and provides an analog output of either voltage or current that is proportional to the input signal.

Model WV418 is powered by a flexible 9 to 30 V DC and is field configurable via DIP switches for 2-, 3-, or 4-wire, Pt100 RTDs of either alphas of 0.00385 or 0.00392, as well as Copper Cu10 RTDs. Analog outputs include 0-10VDC, 0-20mA or 4-20mA and are fully configurable for the up to 95% of the range. This outstanding flexibility ensures that the device is available off-the-shelf, just when you need it, thereby reducing your inventory carrying costs. Configuration via DIP switches is remarkably simple and enables maximum setpoint resolution. The WV418 is supported by a LIFETIME WARRANTY.

TouchCAL(TM) technology, a standard feature on the WV418, replaces the mechanical and thermal variability of potentiometers with the electronic stability of a microprocessor. This enables 100% adjustment of setpoints and deadbands and carries with it a string of benefits. It provides a reliable, digitally stable circuit ensuring better long-term performance and reliability. Calibration is as quick and easy as inputting the setpoint and deadband levels and pressing a recessed button to store the values in non-volatile memory.
