Description
OMRON CS1W‑BC103
Technical Specifications: Total available module slots: 10 slots; first slot dedicated for power‑supply‑unit installation; second slot reserved for CPU‑unit installation; remaining 8 slots for I/O and special‑function modules; compatible hardware scope: CS1‑series power‑supply units, CPU units, I/O units, special‑function units and communication units; internal backplane bus DC5V power‑distribution capacity determined by matched power‑supply unit; operating temperature 0‑55°C; storage temperature ‑20‑75°C; operating humidity 10‑90%RH without condensation; CE, UL certification; weight 720 g; DIN‑rail mounting structure.
Functional Features: Standard 10‑slot CPU main‑rack backplane for CS1‑series PLC system; dedicated slot layout for power‑supply unit and CPU unit; gold‑plated spring contact strips guarantee stable electrical connection with each inserted module; support expansion connection with CS1‑series expansion racks via expansion‑cable interface; full compatibility with full‑range CS1‑series standard hardware modules.
Application Scenarios: CS1‑series standard non‑redundant PLC system main‑rack carrier; medium‑and‑large‑size factory automation control cabinet PLC main frame; spare‑part replacement for legacy CS1‑series automation installations.
Performance Parameters: Gold‑plated spring‑contact structure resists oxidation and guarantees long‑term stable bus‑signal transmission; mechanical‑structure vibration‑resistance complies with industrial cabinet‑mount‑equipment standards; support continuous 24‑hour long‑term running of CS1‑series control system.
Material Composition: Black high‑strength flame‑retardant engineering‑plastic rack housing; internal multilayer glass‑fiber backplane printed‑circuit board; large‑quantity gold‑plated spring bus contact strips; metal reinforcement frame; metal spring‑loaded DIN‑rail mounting buckle; side expansion‑cable connection terminals.
Structural Features: Long rectangular rack‑style backplane profile; rear‑side integrated spring‑type DIN‑rail buckle for cabinet installation; front‑side 10 module slots, each slot equipped with gold‑plated spring backplane contacts; dedicated interface terminals on one side for connecting CS1‑series expansion cables; mechanical locking clips for each inserted module.
Working Principle: CS1W‑BC103 acts as physical power‑distribution and signal‑transmission carrier for CS1‑series main‑rack modules. After power‑supply‑unit is installed into first slot, DC5V working power distributes to every slot through internal backplane copper traces. Parallel CS1‑series backplane‑bus signal transmits between CPU unit and all I/O, special‑function modules via gold‑plated spring contact strips. Side‑mounted expansion‑cable interface completes signal interconnection with external CS1‑series expansion backplane racks.
Installation Requirements: Secure CS1W‑BC103 onto standard cabinet DIN rail; install CS1‑series power‑supply unit into absolute leftmost slot, install CS1‑series CPU unit into second slot; insert other I/O and special‑function modules into remaining slots; use certified CS1‑series expansion cables when connecting with expansion racks; implement reliable protective grounding for control cabinet.
Usage Notes: This backplane applies to standard CS1‑series non‑redundant system; cannot be used for CS1D duplex redundant CPU system; confirm total power consumption of all installed modules does not exceed rated output capacity of matched power‑supply unit; do not deploy in environments with corrosive gas, heavy dust or condensation; regularly inspect locking state of each inserted module.
