Note: 1. A shielded transmission cable or a VCTF cable with a thickness of 0.75 mm
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:
Current leakage:
