10-3. BCD Parallel Data Output Interface
The BCD data output is an interface to take out measured weight values as BCD data.
It is a convenience to perform processing, such as control, totaling, and recording as connected with
a computer, process controller, sequencer, etc.
The Input/Output circuit and internal circuit are photocoupler-insulated electrically.
10-3-1. Control Connector-Pin Assignment
＊ : The COM (common) terminals are connected inside.
10-3-2. Equivalent Circuit (Input)
A signal is inputted to the signal input circuit by short-circuiting or opening the input terminal and
the COM terminal. Short-circuiting is effected by means of a contact (such as a relay or a switch) or
a noncontact (such as a transistor or an open-collector TTL).
Adaptable connector : DDK 57-30360 or equivalent one
