Product Introduction
The Yaskawa JAMSC-B2732V is a legacy analog output module used in Yaskawa Memocon-SC PLC architectures. Its primary job is to convert PLC data into bipolar analog voltage commands, with two output circuits covering −10 to +10 V. The module provides selectable 10-bit and 12-bit resolution, making it suitable for control applications where an analog reference is required.
In a plant environment, the JAMSC-B2732V is more likely to be encountered during maintenance of an older Yaskawa control system than in a new PLC project. Its −10 to +10 V outputs can be used for equipment such as drive references, proportional control devices, or other analog-command interfaces. Because the part is discontinued, preserving the existing rack configuration and matching the module’s resolution settings are important during replacement.

Application Scenarios & Field Pitfalls — Engineer’s Perspective
Engineering Pain Point
A failed JAMSC-B2732V can appear as an incorrect speed reference, valve command, position command, or other analog-control problem. Before replacing the module, verify whether the problem follows the module or originates from field wiring, the receiving device, the PLC program, or the module’s resolution configuration.
Typical Applications
- Yaskawa Memocon-SC PLC systems
- Analog speed or frequency reference generation
- Proportional valve and actuator control
- Legacy machine-control systems requiring bipolar analog signals
Technical Pitfalls to Avoid
- Check the output polarity and range.
The JAMSC-B2732V is specified for −10 to +10 V output. Do not substitute a 0–10 V or 4–20 mA module simply because it fits the same general PLC family. - Verify the resolution switch setting.
The module supports 10-bit and 12-bit modes. A replacement should reproduce the original configuration rather than assuming that the highest available resolution was used. - Do not confuse B2732V with neighboring B27xx modules.
Yaskawa’s , B2733V, B2742V, and B2743V are different modules. In particular, B2733V and B2743V should not be treated as direct equivalents without checking their I/O functions.

Procurement Check
Before purchasing a , verify:
- Exact model:
- Manufacturer: Yaskawa Electric
- Existing Memocon-SC rack/platform
- Two-channel analog-output requirement
- −10 to +10 V signal requirement
- Original 10-bit or 12-bit setting
- Connector and terminal arrangement
- PLC program scaling
- Field-device input range
- Module revision
- Condition of the replacement unit
- Whether the unit has been electrically tested
Recommended procurement description:
Ya Memocon-SC PLC Analog Output / Processor Module, 2-Channel −10 to +10 V Analog Output, Selectable 10-Bit / 12-Bit Resolution, 5 mV Maximum Resolution at 12-Bit.
The main replacement criterion is not simply the part number. Confirm the Memocon-SC rack, output range, channel assignment, and resolution setting before installing a replacement. Since this is a discontinued Yaskawa module, preserving the original configuration is particularly important for an older production machine.
