Environmental Conditions
Normal operating conditions
• Ambient temperature: -10 to 50°C (-10 to 40°C for
side-by-side mounting of controllers)
• Ambient humidity: 20 to 90% RH (no condensation)
• Magnetic field: 400 A/m or less
• Continuous vibration (at 5 to 9 Hz) Half amplitude of
1.5 mm or less
(at 9 to 150 Hz) 4.9 m/s
2
or less, 1 oct/min for 90 min-
utes each in the three axis directions
• Rapid vibration: 14.7 m/s
2
, 15 s or less
• Impact: 98 m/s
2
or less, 11 msec.
• Installation altitude: 2,000 m or less above sea level
• Warm-up time: 30 minutes or more after the power is
turned on
• Start-up time within 10 s
Transportation and Storage Conditions
• Temperature: -25 to 70°C
• Temperature change rate: 20°C per hour or less
• Humidity: 5 to 95%RH (no condensation)
Effects of Operating Conditions
• Effect of ambient temperature
For voltage or TC input:
±1 μ V/°C or ±0.01% of F.S. (instrument
range)/°C, whichever is greater
For RTD input:
±0.05°C/°C (ambient temperature) or less
For current input:
±0.01% of F.S. (instrument range)/°C
For analog output:
±0.02% of F.S./°C or less
• Effect of power supply fluctuation:
For analog input: ±0.05% of F.S. (instrument range)
or less
For analog output: ±0.05% of F.S. or less
(Each within rated voltage range)
Retransmission Output Specifications
• Number of points: 1 point
• Output function: current output
4 to 20 mA DC or 0 to 20 mA DC/load
resistance 600 Ω or less
• Current output accuracy (conversion accuracy from
PV display on the set scale): ±0.1% of span (how-
ever, ±5% of span for 1 mA or less)
The accuracy is that in the basic operating
conditions: 23 ±2°C, 55 ±10%RH, and power
frequency at 50/60 Hz
This is not conversion accuracy through input
and output but the performance of transmission
output itself.

• Input type: no-voltage contact input or transistor con-
tact input
• Input contact capacity: 12 V DC, 10 mA or more
Be sure to use a contact with a minimum ON
current of 1 mA or less
• ON/OFF detection
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: 250 ms
• Application: Confirmation operation, etc.
