Dual-Channel Current Output
4–20 mA
IMPORTANT: The mounting rack connector has 24 pins; the
module connector has 20 pins. The extra pins on the
mounting rack connector prevent misalignment of the
module during installation.
Description
The SNAP-AOA-23 module provides a nominal output range of 4
mA to 20 mA. An external loop power source is required for the
current loops.
NOTE: Both channels share common reference terminals.
Common reference terminals are 3, 4, 7, and 8.
