From a solid-state circuit (proximity sensor, photoelectric sensor, or
the like) with rated power supply voltage ranging from 6 to 30 VDC,
input signals can also be applied by other than an open collector type
transistor as shown in the following diagram. The input signal from a
solid-state circuit is applied when output transistor Tr turns ON. In
terms of signal voltage, the signal is input when it goes from a high to
low level. Again, the residual voltage should be 1 V (max.) when the
transistor is ON. As the current output from the timer to Tr is
approximately 0.1 mA, this connection is possible provided the
residual voltage is kept to a maximum of 1 V.
Solid-state circuit (proximity sensor,
photoelectric sensor, etc.)
Note: Except for the power supply circuitry, avoid the laying of input
signal wires in parallel or in the same conduit with high-tension
or power lines. It is recommended to use shielded wires or
wiring with independent metal conduits for the shortest
possible distance.
