The remote RTD inputs convert values of input resistance into temperature for further operations. These inputs are
intended to be connected to any of the RTD types in common use. Hardware details are contained in chapter 3.
On power up, the M60 reads and saves all application and type settings from the RRTD. This synchronizes the RRTD and
M60. Any changes to RRTD settings (function, application, or type) from the M60 interface are immediately reflected in the
RRTD. The following rules are followed:
• If the setting is "Enabled," then the
RRTD 1 FUNCTION
• If the setting is "Disabled," then
RRTD 1 FUNCTION
• If the

• If the

An RRTD actual value of –43°C implies that the
setting is "None."
APPLICATION
If the RRTD communication link with the M60 is broken, then the last temperature actual values are retained until the RRTD
communication failure is detected. When this occurs, a RRTD COMM FAILURE self-test alarm and target message is
generated, an event is logged in the event recorder, and the temperature actual values are reset to 0. When the link is re-
established, the
