Siemens Building Technology 243-0011 Relay
The Siemens 243-0011 pneumatic relay is a versatile heavy-duty analog relay designed for demanding commercial HVACR control environments. This multi-function auxiliary device operates on a force-balance principle, utilizing a Powers two-valve design to maintain system stability and eliminate unnecessary air consumption. Built as a rugged die-cast model, it features 1/8" NPT air connections for supply, output, and both direct and reverse acting inputs, making it an essential component for pneumatic control system optimization.
This unit is engineered for precision signal conditioning, supporting tasks such as differential pressure control, summing, signal amplifying, and ratio control. With a maximum supply pressure rating of 30 psi and a standard spring range of 0 to 25 psi, it handles signal characterization without requiring field calibration or complex adjustments. The internal relief assembly is a critical fail-safe, preventing signal lock-up during air supply loss. Contractors can install this Siemens building technology relay in any orientation using the included integral mounting brackets for wall or panel applications.
- Multi-Function Versatility: Direct and reverse acting inputs allow for summing, amplifying, and ratio control in a single device.
- Industrial Durability: Heavy-duty die-cast construction with 1/8" NPT ports ensures a leak-free interface compared to lightweight plastic alternatives.
- Low Maintenance: Factory-calibrated design operates effectively across a 40°F to 120°F range without the need for periodic adjustments.
- High Stability: The specialized two-valve configuration minimizes air waste while maintaining extremely low hysteresis (within 0.25 psi).
Common Questions
Does this relay require specific mounting?
No, the 243-0011 can be mounted in any position—horizontal, vertical, or at an angle—without affecting the pneumatic signal precision.
Can I use this for both direct and reverse acting applications?
Yes, it functions as a multi-purpose device with ports for both types of input variables, allowing for signal advancing or pressure transfer functions.
What happens if the air supply is lost?
The internal relief assembly ensures a fail-safe operation, preventing pressure lock-up at the output port (Port R) to protect downstream actuators.
