Note: 1. A shielded transmission cable or a twisted pair or VCTF cable with a thickness of 0.75 mm
2
minimum must be used for signal
transmission. If the twisted pair or 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 transmission setting, these values are possible without grounding the shielded line.

Weight
Approx. 230 g
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.
