16 ms

2.4 ms

Operating voltage range

12 to 24 VDC (10.8 to 26.4 VDC)

Insulation resistance

100 M

Ω min. (500 V) between each terminal and external parts

Dielectric strength

1,000 VAC, 50/60 Hz for 1 min between each terminal and external parts

Noise immunity (see note 3)

Noise level: 1.5 kV; pulse width: 100 ns to 1

µs (on transmission line due to coupling)

Vibration resistance

10 to 55 Hz, 1.5-mm double amplitude

Shock resistance

300 m/s2

Ambient temperature

Operating: –10 to 55

°C (with no icing or condensation)

Storage:

–25 to 65

°C (with no icing or condensation)

Ambient humidity

Operating: 35% to 85% (with no condensation)

Note:

1. A shielded transmission cable or a VCTF cable with a thickness of 0.75 mm2 minimum must be used for signal transmission. If the

VCTF cable is used, however, the transmission distance will be 10 m maximum regardless of whether or not independent power

supplies for the Input and the Output Link Terminals are used.

2. The minimum input time is required for the B7A/B7AS to read an input signal.

3. For high-speed models, these values are possible without grounding the shielded line.

S m

Weight

Approx. 230 g

Note:

1. Two-wire sensors must satisfy the following requirements:

Residual voltage:

4 V max.

Current leakage:

1.5 mA max.

The lower limit of control output:

3 mA (Use a bleeder resister to eliminate this restriction.)

2. Consumption when all 32 points are ON. Excludes external sensor current consumption.

3. Factory-set to normal speed (typical 19.2 ms).

4. The minus sign indicates that the current is flowing out from input terminals.
