Problem: I want to use a single device to provide local indication of temperature, alarm and shutdown relays. I also need to send an isolated 4-20mA signal to my DCS for the same temperature. Can I use the same device for all of these functions?
Solution: Yes! The SPA2 Programmable Alarm Trip that takes temperature sensor inputs (-TPRG) provides all of these functions in a single instrument. In fact, you can even set one of the relays to alert you to a failed sensor without initiating an alarm or shutdown. The SPA2 can be supplied in our NEMA 4X R-BOX enclosure for field mounting.
