The F-8019 is a 16-bit, 8-channel thermocouple input module that features programmable input range on
all channels. It measures millivolt input (±15mV, ±50mV, ±100mV, ±150mV, ±500mV), voltage input (±
1V, ±2.5V, ±5V, ±10V) and thermocouple input (Type J, K, T, E, R, S, B, N, C). An external CJC is supported
for accurate termperature measurement. Moreover, this module has ±0.05% accuracy for highly accurate
application. Besides, the F-8019 provides 3000V
DC
optical isolation between channels and backplane bus.
If any high voltage or current damages these channels, this module won’t affect other component in
iDCS-8000 system.
