Automation Components Inc (ACI) PTS4.1 Control
The Automation Components Inc (ACI) PTS4.1 is a high-performance digital to pneumatic transducer designed to convert dual digital increase/decrease signals into high-precision proportional pneumatic signals. Ideal for compressor staging applications and HVAC pneumatic control systems, this unit supports jumper-selectable ranges including 0-15 psig and 0-103 kPa. Featuring a closed-loop electronic design, the PTS4.1 utilizes an on-board microprocessor and a solid-state pressure transducer to maintain the last commanded pressure with 255 steps of resolution. In the event of a power failure, both internal valves close to prevent branch line bleed, ensuring system stability. This pressure transducer is compatible with relay contact closures, transistors, or triac inputs, making it a versatile solution for modernizing pneumatic control systems. Its ability to automatically reboot during brown-out conditions ensures reliable long-term performance in demanding industrial environments.
Key Benefits- Precision Control: Features 255 steps of resolution for smooth, accurate pressure adjustments over a 90-second full-scale change.
- System Reliability: The closed-loop design ensures the unit maintains the last commanded pressure even if the control signal is lost.
- Fail-Safe Operation: Automatically closes both valves during power loss to preserve branch line pressure and protect downstream equipment.
- Flexible Integration: Jumper-selectable output ranges and compatibility with multiple input signal types simplify installation in diverse setups.
How does the PTS4.1 handle power interruptions?
During a power failure, the unit closes its valves to shut off main air and prevent branch line bleed. Upon restoration of power following a brown-out, the processor resets and defaults the branch pressure output to 0 psig.
What types of input signals can this transducer accept?
The device is designed to accept two digital signals (up/down) from relay contact closures, transistors, or triac inputs.
Can I change the output pressure range in the field?
Yes, the pneumatic output range is jumper-selectable, allowing for 0-15 psig, 5-15 psig, or various kPa scales to meet specific application requirements.
