(2) Output circuit
+24 V
If an incandescent lamp is used, be sure to insert a protection resistor (120 Ω or
Note:
over) in series with the incandescent lamp to limit the rush current to 200 mA or
less.
(3) Over Load Protection
Over load protector is added onto output signal circuit. When a output signals is
shorted, the protector works and cut the current to protect the output circuit.
The protector works for each 8 points of output. In order to work a circuit properly,
separate the 24VDC power for each 8 points of output from the 24VDC for other
outputs as shown Fig. 4.6.8.
