YASKAWA JAMSC-B2732V High-performance analog output module

The YASKAWA JAMSC-B2732V is a high-performance analog output module belonging to the Memocon-SC GL series (specifically the GL40S, GL60.

and RIO2000 families) of Programmable Logic Controllers (PLCs).

It is used to provide precise voltage control signals to external devices like variable frequency drives or proportional valves.

1. Introduction

The JAMSC-B2732V is an Analog Output Module designed for legacy Yaskawa PLC systems. It converts digital data from the CPU into standard analog voltage signals. A key feature of this module is its versatility in resolution, allowing users to toggle between 10-bit and 12-bit modes via physical switches on the board to match the precision requirements of the application.

3. Product Advantages and Features

Dual Resolution Modes: The ability to switch between 10-bit and 12-bit allows it to be used in systems requiring standard speed or high-precision control.

Bipolar Output: Supports a full range of $-10$V to $+10$V, making it ideal for controlling motors that require both forward and reverse speed commands from a single signal.

Circuit Isolation: Designed with internal isolation to prevent electrical noise from the field devices from interfering with the PLC’s sensitive CPU logic.

Compact Reliability: Part of the established Memocon-SC family known for long-term stability in heavy industrial environments.

4. Application Cases

The JAMSC-B2732V is typically used in control loops requiring variable signals:

Speed Control: Providing the frequency reference (0–10V) to AC/DC motor drives.

Pressure Regulation: Controlling proportional valves in hydraulic or pneumatic systems.

Heating Control: Interfacing with power controllers to adjust temperature based on PID logic.

Legacy Robot Interfacing: Used in older cells where the PLC provides analog position or speed overrides to a robot controller.

5. Other Models in the Same Series

The Memocon-SC GL and RIO2000 series includes various I/O and processor modules that often work alongside the B2732V:

JAMSC-B2733V: A related Analog Input module.

JAMSC-B2700V: A standard Digital Output module.

JAMSC-B2742V: A specialized PLC logic or communication module.

JAMSC-B2505: 100V AC Input module for the same rack system.

JAMSC-B2601: 12/24V DC Digital Input module.

Maintenance Tip: Since this is a discontinued legacy part, ensure the Mode Switches (10-bit vs 12-bit) on the replacement module match the settings of the original board before installation, or the PLC code may interpret the output values incorrectly.
