For no-voltage contact input:
Contact resistance 1 kΩ or less in ON state
Contact resistance 50 kΩ or more in OFF state
Transistor contact input:
2 V or less in ON state
Leak current 100 μ A or less in OFF state
• Status detection minimum hold time: control period
+ 50 ms

Analog Output Specifications
• Number of points
Control output (heating-side output): 1 point
(standard), which is shared with transmission
output
Cooling-side output: 1 point, which is
shared with transmission output
• Output functions
Current output or voltage pulse output
• Current output
4 to 20 mA DC or 0 to 20 mA DC/load resistance
600 Ω or less
• Current output accuracy
±0.1% of span (however, ±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
Application: 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 value,
whichever is larger
