Addressable Device Circuit Wire Selection Guide
Each addressable device circuit must meet the following requirements:
 Total loop resistance - 50 ohm maximum with 252 devices. (Refer to following graph.)
 Total loop capacitance - 0.5uF max line to line and 1.0uF max line to shield
Line Resistance Graph
The terminal blocks of Faraday X1 devices are rated for a maximum of 14AWG wire.
