1090-2000-1

The 1090-2000-1 is a DC Input field configurable Limit Alarm with single/dual trip (2 SPDT, 5A) output equipped with a dual function diagnostic LED. The green centre LED indicates line power and input signal status. Active line power is indicated by an illuminated LED. If the input signal is above 100% full scale, the LED will flash at approximately 8Hz. Below 0%, the flash rate is approximately 4Hz. This alarm can be configured for HI, LO, latching or failsafe trip operation. Non-latching HI and LO set points have respective HI and LO dead bands. In a tripped condition, the set point is exceeded and the appropriate red LED will illuminate. The trip will reset only when the process falls below the HI dead band or rises above the LO dead band. To reset a latched set point the signal must be in the safe region and the line power turned off for at least 5 seconds. For proper dead band operation, a HI set point must always be set above a LO set point.
