WV128-2000 (non-latching)
WV128-2001 (latching)

Description
The Ultra SlimPak II is an exciting new line of isolating signal conditioners from Action Instruments with greater accuracy and better stability than virtually any other signal conditioners on the market today.

The WV128 is a Thermocouple Input Limit Alarm with dual setpoints and two contact closure outputs. The input type and alarm functions are field configurable, offering maximum flexibil- ity. There are seven thermocouple types (B, E, J, K, R, S and T) from which to choose. Alarm setpoints are fully adjustable throughout the entire range.

The WV128-2000 contains two standard non-latching SPDT relays. When power is removed, the relays revert to their non-powered state. The WV128-2001 contains two latching relays. Whatever position the relays are in when power is removed is where they will remain when power is re-applied (a reset switch is provided to reset the relays after the alarm is no longer true). Both models are configurable as a single or dual setpoint alarm, with HI or LO trips. The WV128-2000 supports failsafe or non-failsafe operation. In failsafe operation the relay coil is energized when the process is below the HI setpoint or above the LO setpoint (opposite for non- failsafe). In the failsafe mode, a power failure results in an alarm state output.

Operation
Each of the alarm setpoints has a respective HI or LO deadband. Red LEDs will illuminate indicating an alarm condition. The trip will reset only when the process falls below the HI deadband or rises above the LO deadband. (The WV128-2001 requires pressing the reset switch in order to reset the relays after being tripped.) The deadband can be left at the minimum level (the factory default) or can be set to whatever level is desired.
