Using the BCD parallel data output interface (option)
BCD data output is an interface to retrieve a weight value as a BCD code data. This interface is
convenient for processing such as controls, totals, and records by connecting to a computer, process
controller, sequencer, etc. The I/O circuit and internal circuits are electrically insulated with a photo-
coupler.

Connector pin assignments
*: The common (COM: 1, 19pin) is internally connected.
6-12-2.
Equivalent circuit (input)
The signal input circuit inputs signals by making a short-circuit or open-circuit between the input
terminal and COM terminal. Short-circuit is achieved with contacts (relays, switches andso on) and
non-contacts (transistors, TTL open collector output and so on).
Compatible connector: 57-30360 manufactured by DDK (accessory) or equivalent
