3.2Application precautions for output signals

!	WARNING	Configure emergency stop and safety interlocking circuits outside the
		T1-16S. Otherwise, malfunction of the T1-16S can cause injury or serious
		accidents
!	CAUTION	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.

(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.
