Moore Industries SPA2 programmable alarm trip with updated alarm functions

The Moore Industries SPA² standalone alarm trip now offers updated alarm options that allow the user to set up more specific alarm functions. It provides high or low limit process alarms while monitoring industrial processes and warns of unwanted process conditions, providing emergency shutdown or simply executing on/off control. The Band Alarm feature combines the high and the low trip alarms into one alarm to warn of a process that has left its normal operating conditions. Alternatively, the Band Alarm may be configured with a single set point and deviation setting.

The Stuck Input Alarm monitors the input with respect to time and trips when that input hasn’t changed by a user-selected rate (delta) over a user-selected time period (delta time). The rate-of-change (ROC) alarm has been updated and now includes alarming on a process variable that is rising, falling or moving in either direction too fast. The fault alarm now includes input saturation to identify when the input signal exceeds 110% of calibrated input range, an out-of-range alarm and a broken wire alarm. The Copy Alarm setting allows the user to duplicate the exact setting of any other alarm. The product provides users the ability to set up the alarms using onboard controls or the company’s PC-based configuration software.

The device has the ability to accept input signals from transmitters, temperature sensors, resistance and potentiometer devices, and direct millivolt sources. It features 20-bit input resolution; long-term stability (five years); and a metal, RFI-resistant, DIN-mount housing.
