B7A Communications Specifications

Item	Specifications
Transmission method	One-way time-sharing multiplex transmissions
Transmission delay (communications delay on transmission path)	High-speed	3 ms typical, 5 ms max.
	Standard	19.2 ms typical, 31 ms max.
Transmission points	CS1W-B7A12	32 inputs (2 ports)
	CS1W-B7A02	32 outputs (2 ports)
	CS1W-B7A21	16 inputs (1 port), 16 outputs (1 port)
	CS1W-B7A22	32 inputs (2 ports), 32 outputs (2 ports)
External power supply voltage *1	12 to 24 V DC (allowable voltage range: 10.8 to 26.4 V)
External supply current *2	CS1W-B7A12	20 mA min.
	CS1W-B7A02	60 mA min.
	CS1W-B7A21	30 mA min.
	CS1W-B7A22	60 mA min.
Minimum input time *3	High-speed	16 ms
	Standard	2.4 ms
Transmission distance	High-speed	Power supply on one side (common power supply)	10 m max.
			50 m max. (with shielded cable)
		Power supply on both sides (separate power supplies)	10 m max.
			100 m max. (with shielded cable)
	Standard	Power supply on one side (common power supply)	100 m max.
		Power supply on both sides (separate power supplies)	500 m max.
Cables	VCTF, 0.75 mm2, 3 conductors (power supply on one side (common power supply)) VCTF, 0.75 mm2, 2 conductors (power supply on both sides (separate power supplies)) Shielded cable, 0.75 mm2, 3 conductors (power supply on one side (common power supply)) Shielded cable, 0.75 mm2, 2 conductors (power supply on both sides (separate power supplies))

*1. Use a SELV power supply with overcurrent protection. A SELV power supply refers to a power supply with double or
       reinforced insulation 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. 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.
           2. When a common power supply is used, the B7A Interface Unit and B7A Link Terminal are supplied by the same
                external power supply.
