The universal SPA2IS Programmable Limit Alarm Trips provide on/off control. It will warn of unwanted process conditions, alarm on rate-of-change and provide emergency shutdown. Very versatile, they accept a signal input from of monitoring and control instruments.
The SPA2IS includes intrinsically-safe field connections which provide the necessary protection typically afforded by a galvanically isolated intrinsically-safe barrier, without having to install them separately.
• Current and Voltage Signals
• 23 RTD Types
• 9 Thermocouple Types
• Resistance and Potentiometer Devices
• Direct Millivolt Sources
The 4-wire (line/mains-powered) SPA2IS provides two or four independent and individually-configurable alarm relay outputs. These trigger when a monitored process variable falls outside of user-set high and/or low limits. This is typically used to activate a warning light, annunciator, bell, pump, motor or shutdown system.
Using the front panel pushbuttons or the PC Configuration Software, precise zero and span settings can be made in seconds. Just select the zero and span values, and the push of a button locks the values into the alarm trip’s memory.
