6-12. 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.
6-12-1.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).

- Do not apply voltage to the signal input circuit from outside.
- An external element must be an element in which Ic=10mA
or more can be applied.
- External element leak must be 100μA or below.
