Electrical life: 100,000 cycles, Output action: P control, ON/OFF control
Transmission
Converting conductivity, temperature or MV to analog signal every input sampling period,
output 1
outputs the value in current. (Factory default: Conductivity)
If Transmission output 1 high limit and low limit are set to the same value, Transmission
output 1 will be fixed at 4 mA DC.
Transmission output can be indicated with the bar graph.
Resolution: 12000
Current: 4 to 20 mA DC (Load resistance: Max. 550 )Output accuracy: Within 0.3% of Transmission output 1 span
Self-diagnosis
The CPU is monitored by a watchdog timer, and if an abnormal status occurs, theinstrument is switched to warm-up status.
