SPA (MOORE INDUSTRIES)

The universal SPA Site-Programmable Alarms provide on/off control, warn of trouble, or provide emergency shutdown. They accept a direct input from transmitters, temperature sensors, and a wide array of other monitoring and control instruments: Current and Voltage Signals, 23 RTD Types, 8 Thermocouple Types, Resistance and Potentiometer Devices, Direct Millivolt Sources. They provide two or four alarm relay outputs when a monitored process variable falls outside of user-set high and/or low limits. Connect the 4-wire (line-powered) SPA to a warning light, annunciator, bell, or shutdown system, and your process is protected by a simple, highly reliable, independent warning and/or shutdown strategy.
