integrated with various production operations. The following factors
will affect the performance of the switch logic circuit:
• Excessive leakage current in parallel-connected load-
powered devices
• Excessive voltage drop in series-connected devices
• Inductive feedback with line-powered sensors with parallel
connections
2.9.6.1 Parallel-Connection Logic-OR Function
The binary OR logic in Table 1.9 indicates that the circuit output is
ON (1) if one or more of the sensors in parallel connection is ON.
0 = OFF
1 = ON
