4 General Specifications
153 IB-1501268-K
(21) AI (Multi-analog input)
<Cable side connector type>
Connector : DFMC1,5/12-ST-3,5-LR
Manufacturer: Phoenix Contact
(The cable side connector is attached to the unit.)
(a) Outline of multi-analog input circuit
There are four types of multi-analog input as below:
- Voltage input
- Current input
- Thermocouple input
- Resistance temperature detector input
The measurement mode (voltage measurement, current measurement, temperature (thermocouple)
measurement and temperature (resistance temperature detector) measurement) can be set for each CH
and input corresponding to the mode can be performed.
All CHs (CH1 to CH4) are set to the voltage measurement mode when the machine is delivered.
Precautions
- Input the signal within the appropriate input range for the set measurement mode.
(Note)
Do not input the voltage when the current or temperature (thermocouple or
resistance temperature detector) measurement mode is set. This could result in
faults of the unit. Pay close attention to the combination of the measurement mode
setting and input.
- Running-in is required for about 10 to 15 minutes after the power is ON until the measurement
value is stable.
- Do not apply voltage or current from external devices before turning ON the power of multi-
analog input unit. This may damage the multi-analog input unit.
Turn ON the power of the multi-analog input unit and external device at the same time, or wire
circuit so that the power supply of the multi-analog input unit is turned ON first.
