Configured for high-speed module interconnection and internal DC voltage distribution in SYSMAC CS1-series platforms, the Omron CS1W-BC053 (CS1W-BC053 Base Unit) provides direct physical/electrical execution.

Backplane Catalog Matrix

The CS1W-BC053 belongs to the Omron SYSMAC CS1 CPU backplane family. The prefix CS1W-BC designates main CPU backplane units, while the suffix 053 identifies a 5-slot I/O expansion capacity designed to host a CS1 CPU unit, power supply unit, and up to 5 standard CS1 I/O or special function modules.

Hardware Specifications

Backplane Bus Architecture and Interconnect Execution

The unit integrates parallel backplane trace structures engineered to preserve maximum backplane bus communication velocity across all 5 I/O channels. Internal bus lines support high-density signal distribution, optimize system I/O density scaling, and maintain hardware-layer firmware flash compatibility across installed processing cards and communication modules.

Shipping Package Content

• 1 x Omron CS1W-BC053 CPU Backplane Unit

Mechanical Mounting and Earthing Rules

• Secure the backplane onto an isolated panel plate using M4 screws tightened to 1.2 N.m torque.
• Connect the functional ground (FG) terminal directly to a low-impedance ground bar using 2.0 mm2 or thicker copper wire.
• Never insert or remove CPU, power supply, or I/O modules while the backplane main power supply is energized.
• Verify end-cover placement on the rightmost expansion connector to prevent signal distortion on the system bus.

Frequently Asked Questions

• How many I/O modules can be mounted directly on the CS1W-BC053 backplane?

  The CS1W-BC053 accommodates up to 5 standard CS1 I/O or specialized function modules in addition to CPU and power slots.

• Does the CS1W-BC053 backplane require direct AC line power connection?

  No, the backplane is a passive interconnection chassis that receives power from an installed CS1W power supply module.

• Can I/O modules be hot-swapped on the CS1W-BC053 during live CPU operation?

  No, standard CS1 backplanes do not support live hot-swapping; main power must be turned off prior to module changes.

• What is the primary functional difference between CS1W-BC053 and CS1W-BC083?

  The CS1W-BC053 features 5 available I/O module slots, whereas the CS1W-BC083 provides 8 I/O module slots.

• How is system earthing properly established on the CS1W-BC053 chassis?

  Earth connection is established by bonding the designated FG ground terminal to the main panel earthing point.

• What CPU series are compatible with the CS1W-BC053 backplane unit?

  The backplane supports standard Omron SYSMAC CS1H and CS1G series CPU architecture modules.

• What operating temperature limits must be maintained inside the enclosure?

  Ambient enclosure temperatures around the backplane must remain between 0 and +55 deg C during operation.

• Is an expansion bus cable required if no additional expansion racks are connected?

  No expansion cable is required, but an end cover must be installed on the right-hand bus expansion port.
