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

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. 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 B7AM to read an input signal.

3. As for the high-speed model, these values are possible without grounding the shielded line.

Note:

1. Consumption when all 16 input/output points are ON. Excludes external sensor current for Input Terminals and external load current

and error load current for Output Terminals.

2. Power must be supplied to the three-wire sensor via the positive power supply terminal or from an independent power supply.

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.)

3. Default settings are 19.2 ms and LOAD OFF.
