2.3.6.2 Relay output circuit
Output terminal
This model has a total of 4 common terminals for 14 relay outputs. Therefore, each
common terminal block unit can drive loads with different supply voltage systems
(such as 200VAC, 100VAC, and 24VDC).
Loop insulation
The internal circuit of the programmable controller and the load circuit of the
external circuit are electrically insulated between the relay output coils and
contacts. Besides, the common terminal blocks are separated from each other.
Response time
The response time from when the coil of the output relay is powered on or cut off to
when the output contact is ON or OFF is about 20ms.
Output current
For <250VAC AC voltage, it can drive resistive loads of output current 2A/1 point, and
support inductive loads of <80VA (100VAC or 200VAC) and lamp loads of <100W
(100VAC or 200VAC).
Service life of relay output contacts
Standard life of inductive AC loads such as contactors and solenoid valves:
According to the approximate relays standards derived from our life tests, the
service life of relays is approximately 500,000 times for 20VA loads, 300,000 times for
35VA loads, and 100,000 times for 80VA loads. However, if the load is connected in
parallel with a surge absorber, the service life will be significantly prolonged.
Inductive load
When an inductive load stops, a large directional electromotive force will be
generated between the load and the contacts, and there is an arc discharge in the
process.
Capacitive load
During the use of capacitive loads, the instantaneous inrush current is about 20 to
40 times the conventional current, so please note that the inrush current shall be in
accordance with the current values in the resistive load specifications.
