3.4.1
Transistor output specifications
*1 When using an instruction related to pulse train output or
positioning, make sure to set the load current to 10 to 100mA
(5 to 24V DC).
*2 The transistor OFF time is longer under lighter loads.
For example, under a load of 24V DC 40mA, the response time
is approx. 0.3ms. When response performance is required
under light loads, provide a dummy resistor to increase the load
current.
3.4.2
Handling of transistor output circuit
Output terminal:
The main unit and FX
2NC
input/output extension block have 16
transistor output points per common.
Two COM or +V
U
terminals connected to each other inside the
PLC are provided for outputs.
Connect two COM or +V
U
terminals outside the PLC so that the
load applied to each COM or +V
U
terminal is smaller.
Where indicates:1 to 3
Where
U
indicates:0 to 2
Output current
The ON voltage of the output transistor is approx. 1.5V. When
driving a semiconductor element, carefully check the input voltage
characteristics of the applied element.
