Description
OMRON CS1D‑BI092
Technical Specifications: Total available module slots: 9 slots; maximum installable power‑supply‑unit quantity: 2 units for duplex redundant configuration; applicable system: CS1D duplex CPU single‑I/O expansion system; internal current consumption 280 mA at DC5V; support CS1‑series standard I/O units, special‑function units and communication units; support online unit replacement function; connect to CS1D main rack via CS1W‑CN series expansion cable; operating temperature 0‑55°C; storage temperature ‑20‑75°C; operating humidity 10‑90%RH without condensation; CE, UL, cULus certifications; weight 850 g; DIN‑rail mounting structure.
Functional Features: Designed for CS1D redundant high‑availability control system expansion rack; support installation of redundant dual power‑supply units; online unit replacement allows maintenance‑personnel to swap failed I/O or communication modules without stopping whole PLC system; gold‑plated backplane bus contacts guarantee stable long‑term signal transmission; full compatibility with CS1‑series standard hardware module portfolio.
Application Scenarios: High‑reliability industrial redundant‑control‑system expansion rack; continuous‑process production‑facility PLC control systems; factory critical‑equipment automation control requiring zero‑stop maintenance; spare‑part replacement for legacy CS1D redundant‑automation installations.
Performance Parameters: Gold‑plated backplane 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 redundant 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; screw‑type expansion‑cable connector terminals.
Structural Features: Long rectangular rack‑style backplane profile; rear‑side integrated spring‑type DIN‑rail buckle for cabinet installation; front‑side multiple 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 structure for each inserted module.
Working Principle: CS1D‑BI092 acts as physical signal and power distribution carrier for expansion‑rack modules. After connecting to main rack through expansion cable, backplane bus distributes DC5V power supply and parallel bus signal to every module slot. When executing online unit replacement, dedicated backplane hardware circuit isolates corresponding slot bus signal, so operators can remove and replace single faulty module without disturbing normal communication and operation of other modules on expansion rack.
Installation Requirements: Secure ‑BI092 onto standard cabinet DIN rail; use certified CS1W‑CN series expansion cables to connect ‑BI092 expansion backplane with CPU main backplane; implement reliable protective grounding for control cabinet; reserve sufficient surrounding space for module insertion‑removal operation during maintenance work.
Usage Notes: This backplane only applies to duplex CPU single‑I/O expansion system; do not use for CS1‑series non‑redundant ordinary‑rack scenarios; strictly follow official operation manual procedure when performing online unit replacement; do not deploy in environments with corrosive gas, heavy dust or condensation; regularly inspect expansion‑cable connection fastening condition.
