Description
OMRON CP1W‑CIF01
Technical Specifications: Communication standard RS‑232C; supported baud‑rate range 1200 bps up to 115200 bps; galvanic isolation between RS‑232C circuit and CP1‑series CPU internal circuit; connector type 9‑pin D‑SUB male connector; power supply obtained from CP1‑series CPU internal backplane; internal current consumption 50 mA at 5V; maximum communication cable length 15 m; operating temperature 0‑55°C; storage temperature ‑20‑75°C; operating humidity 10‑90%RH without condensation; weight 30 g.
Functional Features: Add RS‑232C serial port function for CP1‑series CPU units; built‑in electrical isolation prevents serial‑port‑side surge interference from damaging CPU main hardware; support multiple serial protocols including host‑link protocol and Modbus‑RTU; compact plug‑in board structure without occupying extra cabinet DIN‑rail space; compatible with all CP1‑series CPU models with option‑board slot.
Application Scenarios: CP1‑series PLC connecting to serial‑type human‑machine interfaces; communication with barcode scanners, serial printers and other industrial serial peripheral equipment; Modbus‑RTU serial network data exchange; program upload‑download through RS‑232C interface; spare‑part replacement for legacy CP1‑series automation installations.
Performance Parameters: Isolation circuit effectively suppresses industrial‑field serial‑line noise interference; support stable serial communication under various cabinet‑mount industrial‑environment conditions.
Material Composition: Small‑size black FR‑4 printed‑circuit board; RS‑232C protocol transceiver chip; optocoupler galvanic‑isolation components; metal‑shell 9‑pin D‑SUB male connector; gold‑plated spring contact pins for CPU option‑slot interconnection.
Structural Features: Compact plug‑in circuit‑board form factor; gold‑plated spring contact pins on rear side for electrical connection with CP1‑series CPU option‑board slot; front‑panel metal‑shell D‑SUB connector exposed outside CPU housing for serial‑cable plug‑in; small‑size overall structure fully embedded inside CPU housing.
Working Principle: After CP1‑series CPU powers on, CP1W‑CIF01 obtains working power from CPU internal option‑slot contacts. Serial data sent from CPU internal logic passes through optocoupler isolation circuit and RS‑232C transceiver chip, converts logic‑level signal into RS‑232C electrical‑level signal and transmits to external serial‑device via D‑SUB connector. Meanwhile, received RS‑232C‑level signal converts back into internal logic‑level signal through transceiver chip and isolation circuit, then transfers to CP1‑series CPU for data processing.
Installation Requirements: Cut off power supply of CP1‑series CPU before inserting CP1W‑CIF01 into CPU option‑board slot; ensure complete insertion and firm mechanical locking of option board; use qualified shielded RS‑232C communication cables; keep serial‑signal cables away from high‑power motor‑drive cables.
Usage Notes: Maximum communication cable length cannot exceed 15 m; configure baud‑rate, data‑bit, stop‑bit and parity parameters consistent with external serial‑device settings; hot‑plugging D‑SUB connector under power‑on state is forbidden; do not deploy in environments with condensation or corrosive gas.
