Figure 2.1: Installation diagram SA11
2.1 Installation site
The SA11 is weatherproof and can be installed both inside and outside. Select an
installation site that meets the following conditions:
• Mechanical vibrations and shocks are negligible
• No relay switch and power switch are installed close to the device
• There is space mounting the device to the Yokogawa sensor & Yokogawa HOST system
• Not exposed to direct sunlight or severe weather conditions
• Maintenance is possible
• No corrosive atmosphere
• Water Protection: IP67, NEMA Type 4X
2.2 Connecting to the sensor
2.2.1 Direct mounting
The SA11 can be installed directly on top of the Yokogawa labelled sensor by means of the
Variopin connection system. In this case the temperature limit of the device is determined by
the process temperature, limited from -30 up to +100°C / -22 up to +212°F for power supply
+2.7 to +4.5VDC, -30 up to +125°C / -22 up to +257°F for power 4.5 to +5.5VDC.

CAUTION
Place the Variopin connectors securely to guarantee IP67.
