EHELP: Other Options to Mount ECA

EHELP: Other Options to Mount ECA
Q. We would like to use the ECA-DIN in a seismic application. In a worst case scenario of an earthquake, the ECA-DIN must retain its position. We are concerned about the robustness of DIN rail mounting. Is the ECA available with a bolt down option?

EHELP: Signal Limiter and Alarm Trip

EHELP: Signal Limiter and Alarm Trip

Q. On a 4-20mA gas detector, while we replace the cell, the output reverts to 3mA. This causes the device receiving the 4-20mA signal to go into a critical alarm condition and can shut down a critical process. What device do you have that will keep the output at no less then 4mA? It would also be convenient to have this instrument provide me with a 'relay alarm contact output' when my input goes to 3mA. It can be 24Vdc or 120Vac. It should be in a DIN housing.

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?

EHELP: Is there a Dual Signal Isolator/Converter/Splitter for Different Outputs?

EHELP: Is there a Dual Signal Isolator/Converter/Splitter for Different Outputs?
Q. As part of a power distribution process I need a dual signal isolator/converter/splitter that has an input of 0-1mA, outputs of 0-1mA and 4-20mA with 117VAC power input? It needs a DIN housing so it can be mounted in an existing cabinet.
