VERSATILE CONTROL PROGRAMS APPLICATION
Stardard Interface:
¥

RS-232C Communication interface:
Weight data, status and set value can be written or read by a host computer. Weight data, date, time, serial number and code data can be printed by a serial printer.

 

¥ External I/O signal interface:
(A) 4 External input signal:
Contact input it open-collector input isolated with photocouplers.
F-Function selectable 6 I/P modes:
Sensor input / as (ZERO) key / as (WT/CN) key as (GR/NT) key / as (PRINT) key / as (WT/CN) key
(B) 3 External output signal:
Open-collector output isolated with photocouplers.
