Connecting the RS 232/485 interface
for digital platform (Option A16 / 19)
YDO07-X
Instead of an analog/digital converter (ADC),
you could also install a data interface to
connect an intrinsically safe digital weighing
platform or balance (e.g. an IS......-X).

Connecting Intrinsically Safe Data
Cables
Connect intrinsically safe data cables to COM 1
(RS232, RS485 or RS422 and intrinsically safe
control signals). For pin assignments on the data
interface board, see 66015-741-50.
External voltage supply for
At AP1 connected IS platform requires an external
Voltage supply, see document
