10.1 Digital I/O Specifications
The specifications of the digital I/O terminals for the converter for electromagnetic flowmeter: LF600F
are as follows:
■ Digital Output 1(D01) (standard)
Output type:
Transistor open collector
Number of outputs:
1
Capacity:
30 V dc, 200 mA maximum
Digital Output 2(D02)
Output type:
Number of outputs:
Capacity:
Digital Input (DI)
Input signal:
Input resistance:
Number of inputs:
Solidstate relay (non polarity)
1
150 V dc, 150 mA maximum
150 V ac(peal-to-peak), 100 mA maximum
20 to 30 V dc voltage signal
• High input level—20 to 30 V dc
• Low input level—2 V dc maximum
Approximately 2.7 kQ
One point
Each I/O terminal can be used as a specified function terminal when selected.
Terminal COM is the signal COMMON for the other three terminals (DOl, D02 and DI).
Each terminal is isolated from the internal circuits.
(The output terminals are not isolated from each other.)
In standard specification (without digital I/O), semiconductor contact, photo coupler, and
resistor are not built in. Left D02 and DI unconnected.
Contact output 1 (DOl)
