A new sensor decoder which attaches to the valve decoder's 2-wire path, measures sensors that produce 4-20mA outputs. To avoid ground loops and to protect against lightning, the 4-20mA input is galvanically isolated by up to 5KV peak from the 2-wire path. The results from the measurement are reported in 14-bit resolution.  A software update in the BT2 2-wire interface family automatically handles the mix of 8-bit and 14-bit sensors. 4-20mAsenderDataSheet2
