Functions at TC, RTD, and standard signal
Upscale, downscale, and off can be specified.
For standard signal, burnout is determined to have occurred if it is 0.1 V or 0.4 mA
or less.
• Input bias current: 0.05 µA (for TC or RTD)
• Measurement current (RTD): About 0.16 mA
• Input resistance:
TC or mV input: 1 MΩ or more
V input: About 1 MΩ
mA input: About 250 Ω
• Allowable signal source resistance:
TC or mV input: 250 Ω or less
Effects of signal source resistance: 0.1 µV/Ω or less
DC voltage input: 2 kΩ or less
Effects of signal source resistance: About 0.01%/100 Ω
• Allowable wiring resistance:
RTD input: Max. 150 Ω/wire (The conductor resistance between the three wires
shall be equal.)
Wiring resistance effect: ±0.1ºC/10 Ω
• Allowable input voltage/current:
TC, mV, mA or RTD input: ±10 V DC
V input: ±20 V DC
mA input: ±40 mA
• Noise rejection ratio:
Normal mode: 40 dB or more (50/60 Hz)
Common mode: 120 dB or more (50/60 Hz)
For 100-240 V AC, the power frequency can be set manually. Automatic detection
is also available.
For 24 V AC/DC, the power frequency can be set manually.

19.1.2 Analog Output Specifications
• Number of outputs:
Control output: 1
Cooling-side control output of Heating/cooling type (Retransmission output
terminal): 1
• Output type: Current output or voltage pulse output
• Current output: 4 to 20 mA DC or 0 to 20 mA DC/load resistance of 600 Ω or less
• Current output accuracy: ±0.1% of span (±5% of span for 1 mA or less.)
The accuracy is that in the standard operating conditions: 23±2°C, 55±10%RH, and
power frequency at 50/60 Hz.
• Voltage pulse output:
Use: Time proportional output
On-voltage: 12 V or more/load resistance of 600 Ω or more
Off-voltage: 0.1 V DC or less
Time resolution: 10 ms or 0.1% of output, whichever is larger
