SPA2IS: Programmable Limit Alarm Trips with Intrinsically-Safe Field Connections

SPA2IS: Programmable Limit Alarm Trips with Intrinsically-Safe Field Connections

The universal SPA2IS Programmable Limit Alarm Trips provide on/off control, warn of unwanted process conditions, alarm on rate-of-change and provide emergency shutdown. Very versatile, SPA2IS accepts signal inputs from transmitters and temperature sensors that are located in hazardous areas where the method of protection implemented by the plant or facility is Intrinsic Safety. Normally such installations would require the additional use of an intrinsically-safe barrier. The SPA2IS includes intrinsically-safe field connections which provide the necessary protection typically afforded by a galvanically isolated intrinsically-safe barrier. 

The SPA2IS accepts a wide array of inputs:

• Current and Voltage Signals
• 23 RTD Types
• 9 Thermocouple Types
• Resistance and Potentiometer Devices
• Direct Millivolt Sources
