Protection circuit for load short-circuiting
A short-circuit at a load connected to an output terminal could cause burnout at the output device or the PCB.
To prevent this, a protection fuse should be inserted at the output.
■
Minute current load
C-R absorbers are connected in parallel at the triac output circuit for turning off the triac. When a minute current load of 0.4VA
or less/100VAC or 1.6VA or less/200VAC is connected, a surge absorber must be connected in parallel with the load. Select a
surge absorber with voltage rating that is suitable for the output used. For other specifications, refer to the following.
Standard
Electrostatic capacity: Approx. 0.1
F
Resistance value: Approx. 100 to 200
■
Interlock
For loads, such as forward/reverse contactors, where a hazardous condition could result if switched on simultaneously, an
external interlock should be provided for interlocking along with an interlock in the programmable controller program as shown
below.
■
In-phase
Programmable controller output contacts (*1) should be used in an "in-phase" manner.
