1 or 2 (two for heating/cooling type),
switched between a voltage pulse output and current output.
Output signal On-voltage = 12 V or more (load resistance: 600 Ω or more)
Off-voltage = 0.1 V DC or less
Resolution 10 ms or 0.1% of output, whichever is larger

• Input type: Non-voltage contact or transistor open collector input
• Input contact rating: 12 V DC, 10 mA or more
• On/off determination: For non-voltage contact input, contact resistance of 1 k or less
is determined as “on” and contact resistance of 20 k or more as “off.”
For transistor open collector input, input voltage of 2 V or less is determined as “on”
and leakage current must not exceed 100 A when “off.”
• Minimum status detection hold time: PV input’s sampling period 3
