ASR61
Details
The Siemens ASR61 is a specialized replacement electronics module (repair board) designed for Siemens Acvatix refrigerant valves. It allows operators to service the control heads of modular refrigeration valves without needing to replace the entire physical valve body.
🔧 Primary Function & Compatibility
According to official technical listings on the Siemens HIT Portal, the board serves as the direct replacement intelligence unit for the following product families:
- MVL661.. series (Modulating refrigerant valves used for expansion, hot-gas, and suction throttle applications)
- MVS661..N series (Modulating pilot refrigerant valves optimized for refrigeration units, heat recovery, and condensate control)
⚙️ Technical Specifications
As documented by Siemens Smart Infrastructure, the ASR61 operates under standard HVAC power and control loop protocols:
- Operating Voltage: AC 24 V, or DC 20...30 V
- Control Input Signals: Multi-configured to accept DC 0...10 V, DC 2...10 V, or DC 0...20 mA signals
- Enclosure Protection: Rated at IP65 (dust-tight and protected against water jets, essential for condensation-heavy refrigeration environments)
🛠️ Usage Scenario
Instead of cutting or unsoldering a refrigerant line to fix a faulty control circuit, a technician can keep the valve body intact, use the official Siemens ASR.. Mounting Instructions, unscrew the old electronic head, and swap in the ASR61 to restore proper modulating signal control.
Are you troubleshooting an existing MVL or MVS valve that isn't responding, or do you need help locating the official installation wiring manual for this board?
