I/O Wiring Examples
12 +10V DC –
Drive supplied power for 0-10V external potentiometer.
Maximum output current is 15mA.
P108
13 0-10V In
(3)
Not Active
For external 0-10V input supply
(input impedance = 100k ohm) or potentiometer wiper.
P108
14 Analog Common –
For 0-10V In or 4-20mA In. Electronically isolated with
analog inputs from digital I/O.
15 4-20mA In
(3)
Not Active
For external 4-20mA input supply
(input impedance = 250 ohm).
P108
16 RS485 (DSI) Shield –
Terminal should be connected to safety ground - PE
when using the RS485 (DSI) communications port.
(3)
Only one analog frequency source may be connected at a time. If more than one reference is connected at the same
time, an undetermined frequency reference will result.
No. Signal Default Description Param.
