External Connections

• A voltage output (control output 1, for driving SSR) is not electrically insulated from the internal circuits. When using a grounding thermocouple,
do not connect any of the control output terminals to ground. If the control output terminals are connected to ground, errors will occur in the
measured temperature values as a result of leakage current.
The voltage output (control output 2, for driving SSR) has basic insulation provided for the internal circuit
Controllers
• 100 to 240 VAC
• 24 VAC/VDC (no polarity)

A heater burnout alarm, SSR
failure, heater overcurrent
alarm, or input alarm is sent
to the output to which the
alarm 1 function is assigned.
Note: Wire all voltage input terminals correctly. The Controller may fail if voltage input terminals are wired incorrectly.
