Application Precautions For Output Signals - Toshiba PROSEC T1-16S User Manual

3. I/O Application Precautions

3.2 Application precautions for output signals

!
WARNING
!
CAUTION
(1) 2 points of solid-state output
The leading 2 points of output (Y020 and Y021) are solid-state outputs, transistors on
the DC input types.
These solid-state outputs are suited for frequent switching applications.
Note that the specifications of the solid-state outputs and other outputs (relays) are
different.
(2) Switching life of output relays
Expected relay life is more than 100,000 electrical cycles at rated maximum voltage
and current, and more than 20 million mechanical cycles. The expected contact life
(electrical cycles) is shown on the table below.

T1-16S User's Manual
Configure emergency stop and safety interlocking circuits outside the
T1-16S. Otherwise, malfunction of the T1-16S can cause injury or serious
accidents
1. Turn on power to the T1-16S before turning on power to the loads.
Failure to do so may cause unexpected behavior of the loads.
2. Configure the external circuit so that the external 24Vdc power required
for the transistor output circuits and power to the loads are switched
on/off simultaneously. Also, turn off power to the loads before turning off
power to the T1-16S.
3. Install fuses appropriate to the load current in the external circuits for the
outputs. Failure to do so can cause fire in case of load over-current.
