The YASKAWA   JAMSC-B1071 is a Register Output Module belonging to the legacy Memocon-SC series (specifically the 1000 series I/O) of Programmable Logic Controllers (PLCs).

It is designed to output multi-bit numerical data (registers) to peripheral devices like digital displays, timers, counters, or other intelligent controllers.

Introduction

The JAMSC-B1070 functions as a bridge for numerical data exchange between the PLC CPU and external hardware.

Unlike standard discrete output modules that handle simple on/off signals, the B1070 transmits complex values (such as BCD or binary codes)

sequentially using strobe signals to coordinate with external digital switches or displays.

Product Advantages and Features

Efficient Slot Usage: Occupies only one slot on a 1000-series mounting base while handling up to 8 numerical output channels.

Sequential Data Transmission: Uses strobe (select) signals to output multiple data points over a shared set of wires, reducing cabling complexity.

High Compatibility: Fully integrated with the Memocon-SC architecture, appearing as standard output registers in the PLC’s I/O allocation table.

Industrial Hardening: Designed for high-reliability environments with built-in status LEDs for rapid field diagnostics.

Application Cases

Digital Displays: Driving large LED numerical panels on factory floors to show production counts, speeds, or error codes.

Timer/Counter Presets: Sending set-point values from the PLC to external hardware timers or specialized process controllers.

Machine Tool Interfacing: Transmitting tool offsets or coordinate data to older CNC units that accept BCD/binary inputs.

Legacy System Maintenance: Replacing failed units in established production lines where Memocon-SC PLCs are still operational.
