PP Output Analog power supply output
10Vdc
(permissible load
current: 10mA)
VIA Input
Multifunction programmable analog input.
Factory default setting: 0~10Vdc/0~60Hz
(0~50Hz) frequency input.
The function can be changed to
4~20mAdc (0~20mA) current input by
flipping the VIA (SW3) dip switch to the I
position.
By changing parameter setting, this
terminal can also be used as a
multifunction programmable contact input
terminal. When using the sink logic, be
sure to insert a resistor between P24-VIA
(4.7 k
Ω-1/2 W). Also move the VIA (SW3)
dip switch to the V position.

VIB Input
Multifunction programmable analog input.
Standard default setting: 0~10Vdc/0~60Hz
(0~50Hz) frequency input.
PTC thermal input

FM Output
Multifunction programmable analog
output. Standard default setting: output
frequency.
The function can be changed to 0-20mAdc
(4-20mA) current output by flipping the FM
(SW2) slide switch to the I position.
