HIX and HIT: HART Isolators

HIX and HIT: HART Isolators
Moore Industries’ HART® Isolators provide highly economical solutions to common and costly problems that plague many of today’s “smart” process loops. Protect and enhance your HART investment with the 2-wire (loop powered) HIX or the 4-wire (line-mains powered) HIT.

SSX/SST: Safety Series Isolator and Splitter

SSX/SST: Safety Series Isolator and Splitter
Part of Moore Industries’ FS Functional Safety Series, the exida® approved, SIL 3 capable 2-wire (loop powered) SSX and 4-wire (line/mains powered) SST Safety Isolators and Splitters provide isolation and signal conversion for your SIS (Safety Instrumented System) needs. These units protect and enhance loops and also pass valuable HART® data from the field transmitter to host systems and vice-versa.

Sharing Process Variables: HART Functionality

Problem: When sharing a Process Variable (PV) with single or multiple systems, the connection needs to be thought out carefully especially when considering additional scenarios to this application: HART functionality and Safety Instrumented Systems.

E-HELP: Isolating Feedback on VFDs

E-HELP: Isolating Feedback on VFDs
Q: We are a boiler/burner company dealing with a rising amount of computer-based burner controls. We have installed several and have some blowers that are controlled by VFDs (Variable Frequency Drives). We have run into issues with noise on certain systems. We get occasional problems with 4-20mA feedback from the VFD despite going through the proper grounding techniques. We are wondering if installing an opto isolator on the feedback loop might eliminate our issue. We have used the SIX Signal Isolator many times on the signal going to the VFD to offset impedance issues on the VFD. Can we put an opto isolator on both signals?
