1 s (travel time from input 0% to 90%, for step input)
150 ms/4 inputs
Conversion period + one CPU Unit cycle
Detects disconnections at each input and turns ON the Disconnection Detection Flag.
Hardware detection time: Approx. 5 s
The process value overrange direction for when a disconnection occurs can be speci-
fied. (High: 115% of set input range; low: –15% of set input range)
Calculates the moving average for the specified number of process values (1 to 16),
and stores that value in the CIO Area as the process value.
Process value 4-point alarm (HH, H, LL, L), alarm hysteresis, and ON-delay timer (0 to
60 s) are available.
Calculates the amount of change per comparison time interval (1 to 16 s).
Rate-of-change 2-point alarm (H, L), alarm hysteresis (shared with process value
alarm), and ON-delay timer (0 to 60 s, shared with process value alarm) are available.
Between temperature inputs and between input terminals and PC signals: Isolation by
transformer
20 MΩ (at 500 V DC) between inputs
Between inputs: 1,000 V AC, at 50/60 Hz, for 1 min, leakage current 10 mA max.
Terminal block (detachable)
Set by rotary switches on front panel, from 0 to 95.
Three LED indicators on front panel (for normal operation, errors detected at the Ther-
mocouple Input Unit, and errors related to the CPU Unit).
Sensor input connector terminal block (detachable)
0.3 ms
5 V DC at 150 mA max., 26 V DC at 150 mA max.
35 × 130 × 126 mm (W × H × D)
Note The height including the Backplane is 145 mm.
450 g max.
Two cold junction sensors (installed in terminal block)
