Communications Specifications
Note: The baud rate, data bit length, stop bit length, or vertical parity can be individually set using the communications setting level.
Wiring Terminals
• The voltage output (control output) is not electrically insulated from
the internal circuits. When using a grounding thermocouple, do not
connect the control output terminals to the ground. If the control
output terminals are connected to the ground, errors will occur in
the measured temperature values as a result of leakage current.
• Standard insulation is applied to the power supply I/O sections. If
reinforced insulation is required, connect the input and output ter-
minals to a device without any exposed current-carrying parts or to
a device with standard insulation suitable for the maximum operat-
ing voltage of the power supply I/O section.
