ABB Advant OCS DSMB151 57360001-K/10 Memory Display Module

Overview

Configured for high-speed display data buffering in ABB Advant OCS networks, the ABB DSMB151​ (DSMB 151​ Memory Display Module) provides direct physical execution of graphical memory management tasks across Master software platforms.

Hardware Specifications

Firmware Flash Compatibility

Firmware revisions on the DSMB151 must align with the host CPU’s base software version. Attempting to install a module with incompatible firmware will result in a bus timeout error during the power-up sequence. The module utilizes non-volatile flash memory; therefore, configuration data persists through power cycles without requiring battery backup. Cross-compatibility with older DSMB150 modules is limited by memory addressing constraints.

Frequently Asked Questions

Q: Is the DSMB151 hot-swappable while the rack is powered?

A: No. The module must be installed or removed only after removing power from the Advant Controller rack to prevent backplane bus corruption and physical damage to the edge connectors.

Q: What is the typical backplane current draw for this module?

A: Under standard operating conditions with full memory utilization, the module draws approximately 0.5 A at 24 VDC from the backplane power supply.

Field Installation Guidelines

Ensure the module is aligned with the guide rails inside the subrack before applying pressure. Insert the module vertically until the front panel is flush with the rack frame. Torque the securing screws to 0.5 Nm. Verify that the display bus terminators are correctly seated if this is the last module in the chain. All cabling connected to the display interface must maintain a minimum bend radius of 50 mm to prevent signal attenuation.
