Within 1 s
(63% of analog output response time when a step change of 10 to 90% of input span is
applied)
• Contact type and number of outputs:
Control output: contact point 1c; 1 point
Heating/cooling type: contact point 1a; 2 points for both heating and cooling sides
Alarm output: contact point 1a; 3 points (common is independent)
• Contact rating:
Contact point 1c (control output): 250 V AC, 3 A or 30 V DC, 3A (resistance load)
Contact point 1a (control output): 240 V AC, 3A or 30 V DC, 3A (resistance load)
Contact point 1a (alarm output): 240 V AC, 1A or 30 V DC, 1 A (resistance load)
• Use: Time proportional output, alarm output, FAIL output, etc.
• Time resolution of control output: 10 ms or 0.1% of output, whichever is larger
Note: Cannot be used for a small load of 10 mA or less.
• Contact type and number of output: zero cross; 1 point
Load voltage: 75 to 250 V AC
Allowable load current: 0.8 A when the ambient temperature is 20°C, 0.3 A when
the ambient temperature is 50°C.
• Minimum load current: 20 mA (*)
*: Unusable for a small load of 10 mA or less.
*: If there is a risk of surge current, connect a current-limiting reactor, a current-
limiting fuse or a breaker in series to the load power supply.
• Use: Time proportional output, Alarm output
• Time resolution of control output: 1/commercial frequency (s) or 0.1% of output,
whichever is larger.
• Position signal input:
Slide resistance: 100 Ω to 2.5 kΩ of total resistance
100% side and slide line: with disconnection detection
0% side: without disconnection detection
Current input: 4 to 20 mA (with disconnection detection)
• Sampling period: 50 ms
• Measurement resolution: 0.1% of input span
• Position proportional relay output:
UT35A: contact point 1a; 2 points, 250 V AC, 3 A or 30 V DC, 3 A (resistance load)
UT32A: contact point 1a; 2 points, 240 V AC, 3 A or 30 V DC, 3 A (resistance load)
Note: Cannot be used for a small load of 10 mA or less.
• Number of outputs: Retransmission output; 1, shared with 15 V DC loop power supply
or Cooling-side control 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.
