Programmable alarm trips for hazardous areas
SPA2 programmable current/voltage and RTD/thermocouple limit alarm trips from Moore Industries are FM-approved for use in hazardous locations.
SPA2 programmable current/voltage and RTD/thermocouple limit alarm trips from Moore Industries are FM-approved for use in hazardous locations. They provide on/off control, warn of trouble, and provide for emergency shutdown by sending up to four relay outputs when a monitored process signal falls outside a user-selectable high or low limit. SPA2 models accept input signals from transmitters, temperature sensors, resistance and potentiometer devices, and direct millivolt sources; and they provide two or four independent and individually configurable alarm relay outputs. Each relay may be programmed, using on-board controls or the company’s free PC configuration software, as a high- or low-limit process alarm, rate-of-change alarm, input fault alarm, or self-diagnostic alarm. Features include 20-bit input resolution; long-term stability (5 yr); a metal, RFI-resistant, DIN-mount housing; and a large, five-digit process and status readout.
