Technical Data

Number of spot elements and wiring:
Up to 16 RTD spot elements or averaging sensors can be connected to a 2240S.
For Rosemount temperature / water level sensors (models 565, 566 and 765), three wiring types can be used:

• 3-wire RTD with common return (1-16 spot elements)
• 3-wire RTD individual (1-16 spot elements with Rosemount 565, 1-6 spot elements with Rosemount 566, and 1-14 spot elements with Rosemount 765)
• 4-wire RTD individual (1-16 spot elements with Rosemount 565, 1-4 spot elements with Rosemount 566, and 1-10 spot elements with Rosemount 765)
