Description
Control Description The Mixing Expansion Module 444 provides six options for operating a variable speed injection pump, a floating action actuator, or an analog 0-10 V (dc), 2-10 V (dc), 0-20 mA, or 4-20 mA signal. The 444 also provides an output for a system pump. The 444 cannot operate alone and requires the use of a tN4 System Control that is capable of operating a Mixing Expansion Module.
