210 µA
* typically ±5% at 25 °C, ±8% from -20 °C to 65 °C
Voltage Mode ±28 VDC continuous. (Note: maximum voltage
between any two pins must be limited to 28 VDC as well.) For
proper operation, do not connect any external voltages to the
CJC pins.
Current mode 32 mA continuous (approximately 8 V).
50 VAC RMS working Reinforced isolation tested at 2 kVDC
for 1 minute.
50 VAC RMS working Reinforced isolation tested at 2 kVDC
for 1 minute.
10 VDC measured between the IN-leads. Maximum voltage
between any two pins must be limited to 28 VDC. CJC input
pins are not designed to be attached to external voltages.
Over/under range for all types.
Open Circuit detection is supported on all ranges except the 0-20
mA range. You may disable fault detection for volt, millivolt,
and thermocouple measurements.
Note: Voltage and Thermocouple open circuit (open wire) is
periodically checked to keep input impedance high during
normal measurements.
97 mA max
15 mA max
Less than 150 mA at 5 V.
Less than 400 mA at 24 V.
0.9 W maximum in Voltage/TC/Res/RTD modes; 1.8 W
maximum in current mode with all inputs at 21 mA.
