Common FAQ

What is the significance of the "1A" key position?The 1A key position is a physical safeguard on the CHARM baseplate. It ensures that only an Analog Input CHARM can be inserted into a slot wired for an analog transmitter, preventing electrical damage caused by mismatched signal types.

Can I use this CHARM for a 2-wire transmitter?Yes. The KL3021X1-BA1 provides the necessary 24 VDC field power to loop-power a standard 2-wire transmitter, while also receiving the 4-20mA signal and HART data.
