CS1W-B7A Omron Corporation, CS1W-B7A Datasheet - Page 2

• Manufacturer Part Number: CS1W-B7A
• Description: Cs-series B7a Interface Unit
• Manufacturer: Omron Corporation

B7A Communications Specifications
*1. Use a SELV power supply with overcurrent protection. A SELV power supply refers to a power supply with double or reinforced insulation
*2. The capacity of the external supply current does not include the capacity required by the B7A Link Terminal.
*3. The minimum input time is the minimum time required by the B7A Interface Unit to read the input signals from the CPU Unit.
Note: 1. When separate power supplies are used, the B7A Interface Unit and B7A Link Terminal are supplied by separate external power supplies.

between input and output and with an output voltage of 30 V rms with a 42.4-V peak or an output voltage of 60 VDC max. We recommend
OMRON S8@@-series Power Supply Units for the external power supplies.
2. When a common power supply is used, the B7A Interface Unit and B7A Link Terminal are supplied by the same external power supply.
