IM DA100-01E 4-12
4.3 Specifications of mA-input Module
Style Number: S5
Model Code, Number of Input Channels, Terminal Configuration and Shortest
Measurement Interval
Model Code Number of Channels Terminal Configuration Shortest Measurement Interval
DU300-11 10 Screw 0.5 s
DU300-12 10 Clamp 0.5 s
Method of Input
Non-balanced floating input with isolation between channels (separated channels)
Resolution of A/D Conversion
±20000
Integral Time of A/D Conversion
Manual or automatic selection between 20 ms (50 Hz), 16.7 ms (60 Hz) and 100 ms (10 Hz)
However, AUTO does not function if the instrument is the stand-alone DC power supply model,
or the subunit (DS400/DS600) of the DC power supply model. (Selecting “AUTO” will set the
A/D integration time to 20 ms (50 Hz)).
Shortest Measurement Interval and Cutoff Frequency
When the lowpass filter is turned off:
Cutoff frequency: 50/60 Hz 10 Hz
Shortest measurement interval: 0.5 s* 4 s
*: 2s if the power monitor module is installed
When the lowpass filter is turned on:
Cutoff frequency: 50/60 Hz 10 Hz
Shortest measurement interval: 3 s 12 s

Measuring Range/Accuracy
Measured under the following standards of operating conditions:
Reference operation conditions
temperature: 23 ±2°C; humidity: 55 ±10% RH; supply voltage 90 to 250 VAC (AC power supply)
/10 to 32 VDC (DC power supply); supply frequency: 50/60
±1% (AC power supply); warm-up
time: at least 30 minutes; when operating, the system must not adversely affect the operation of
other equipment.
