Press Release Summary:
DIN-rail-mount Model WV118 accepts provides 2 selectable relay output functions and is powered by 9-30 Vdc. It is field configurable via DIP switches for 2- or 3-wire, Pt100 RTDs of either alphas of 0.00385 or 0.00392, as well as copper Cu10 RTDs. Dual relay alarm outputs can be set as high or low alarms to operate in failsafe or non-failsafe modes. TouchCAL(TM) technology enables 100% adjustment of setpoints and deadbands.

Eurotherm, Action Instruments Announces New, Field Configurable, RTD Input Limit Alarm with TouchCAL(TM) Technology
WV Series Model WV118
SAN DIEGO, CA - Eurotherm Action Instruments announces the immediate availability of the new WV Series, Model WV118, RTD input, dual setpoint limit alarm with TouchCAL(TM) technology. This high density, field configurable, DIN rail mount device accepts RTD inputs and provides two selectable relay output functions.
Model WV118 is powered by a flexible 9 to 30 V DC and is field configurable via DIP switches for 2- or 3-wire, Pt100 RTDs of either alphas of 0.00385 or 0.00392, as well as Copper Cu10 RTDs. The dual relay alarm outputs are also field configurable via DIP switches and can be set as high or low alarms to operate in failsafe or non-failsafe modes. 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.
TouchCAL(TM) technology, a standard feature on the WV118, 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.
There are two standard versions of the WV118. The WV118-0000 utilizes standard relays in that when power is removed, the relay transitions to its OFF state. The WV118-0001 incorporates latching relays. When a power loss occurs, the relay remains in its current state. A manual reset is required after power is re-applied in order to reset the relay and clear the alarm. The WV118-0001 does not support failsafe/non-failsafe operation. Both models are supported by a LIFETIME WARRANTY.
