Our loop requires two alarms: one to warn the control room and a second for emergency shutdown. Is there an inexpensive way to accomplish this?
Absolutely. Our SPA2 Programmable Alarm Trip with two relays accepts the 4-20mA input from your transmitter then provides two relay outputs to your DCS... one for warning and the other for shutdown. Industry-best RFI protection and FM Class I, Div 2 approvals make the SPA2 a great field fit for field locations too.
