Functional Parameter Of Analog Quantity - DEMA D5M Series Manual

6.4 Functional parameter of analog quantity

P070
Input channel selection
for analog quantity
There are two channels Al1 and Al2 and three modes to be selected for analog quantity
input:
[Channel 1] 0: 0-10V 1: 0-5V
[Channel 2] 2: 0-20mA/0-10V 3: 4-20mA/2-10V
[Overlying of channel 1 and channel 2] 4: Overlying of 0-10V and 4-20mA/2-10V
[Note] Current or voltage input can be selected by channel 2 through jumper J1
This parameter can be set to satisfy different analog input signals.
When P070=4, output frequency is equal to 1/2 (U/Umax+I/Imax) x50Hz, wherein:
U: analog quantity voltage
I: analog quantity current
P071
Filtering constant of
analog quantity
Setting of this parameter is related to reaction speed of analog quantity; the larger the P071
is set, the slower the analog quantity makes response.
