Omron, S8BA Series

Backup power for 24-VDC devices in control panels for instantaneous voltage drops or power interruptions

New value for control panels

Control Panels: The heart of manufacturing sites.
Evolution in control panels results in large evolution in production facilities.
And if control panel design, control panel manufacturing processes, and human interaction with them are innovated, control panel manufacturing becomes simpler and takes a leap forward.
OMRON will continue to achieve a control panel evolution and process innovation through many undertakings starting with the shared Value Design for Panel *1 concept for the specifications of products used in control panels.

*1 Value design for panel

Our shared value design for panel (herein after referred to as "value design") concept for the specifications of products used in control panels will create new value to our customer’s control panels.
Combining multiple products that share the value design concept will further increase the value provided to control panels.

Smallest*1 DIN rail-mounted ups in its class

Impressive space saving. downsize panels even further by also using slim power supplies.
easy installation and wiring let you reduce assembly work.

*1. An estimated value for standard mounting. Not a guaranteed value.
*2. Conditions: With rated loads connected, at a rated input voltage, and with the battery fully charged.
*3. Conditions: With rated loads connected, at a rated input voltage, and at the maximum battery charging current.
*4. 400 W for use as a UL compliant device.
*5. 20 A for use as a UL compliant device.
*6. 16.7 A for use as a UL compliant device.
*7. When using in an environment at a high temperature, charging may be paused by charging temperature protection,
then the charging time will be longer than specified time.
"CS" will be displayed when charging temperature protection is operated.
*8. For the S8BA-24D24D120LF, install all of the RSMN-2030, RSHN-2030, and RSEN-2030 EMC filters manufactured by
     TDK. For the S8BA-24D24D240LF, S8BA-24D24D360LF, or S8BA-24D24D480LF, install both the RSMN-2030 and
     RSHN-2030 or their equivalents. Install these filters in series to the cable connected to the DC input terminal block.
     When you do, do not connect anything to the GR terminal.
     The effectiveness of the noise filters may be affected by the installation environment. Be sure to check effectiveness
     before starting operation.
