Tekmar Mixing Expansion Module 444 - Variable Speed / Floating
The Mixing Expansion Module 444 is designed to operate a mixing device within a hydronic heating system as part of a tekmarNet® control system. It is capable of controlling a mixed system pump and six optional outputs for mixing: 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.
Features
- Analog 0-10 V (dc) or 2-10 V (dc) output
- Analog 0-20 mA or 4-20 mA output
- CSA C US certified for use in USA and Canada
- Powered 120 V (ac) system pump
- Powered 24 V (ac) floating action output
- Powered 24 V (ac) system pump output
- Powered variable speed injection pump
- Requires a tekmarNet® 4 system control
