Minimum input time (see note 2)

16 ms

Operating voltage range

12 to 24 VDC (10.8 to 26.4 VDC) (see note 1)

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

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)

Storage:

–25 to 65

°C (with no icing)

Ambient humidity

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

Note:

1. The transmission distance values stated in this table are possible if the Input or Output Link Terminal is connected to an independent

power supply. If a single power supply is connected to the Input or Output Link Terminal, the supply voltage must be 24 VDC

±10%,

in which case the transmission distance is 100 m maximum. Refer to

Power Supply on page 89 for details.

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

Mounting strength

No damage when 49-N pull is applied for 1 min each in all directions

(except direction of DIN track)

---

Terminal strength

No damage when 49-N pull is applied for 1 min each in all directions

---

Tightening torque

0.78 to 1.18 N

S m

---

Weight

Approx. 100 g

Approx. 12 g

Note:

1. The polarity of the B7A-TS10S1’s B

j terminal is negative. Therefore, supply power to the three-wire sensor from the positive pow-

er supply terminal or a power supply.

2. Consumption when all 10 points are ON. Excludes external sensor current for Input Terminals.

3. The minimum input time is required for the B7A to read an input signal.
