Isolated Output
Isolated Output Simplified schematic
The output port implements an isolated contact output.
DC characteristics
Parameter | Conditions | Min. | Typ. | Max. | Units |
---|---|---|---|---|---|
Current | 100 | mA | |||
Differential voltage | Open state | -30 | 30 | V | |
Closed state @ 1 mA | 0.4 | V | |||
Closed state @ 100 mA | 1.0 | V |
□ | The output port in the closed state has no current limiter, the user circuit must be designed to avoid excessive currents that could destroy the output port. |
□ | The output port remains in the OFF-state until it is under control of the application. |
AC characteristics
Parameter | Min. | Typ. | Max. | Units |
---|---|---|---|---|
Pulse rate | 0 | 100 | kHz | |
Turn-on time | 5 | µs | ||
Turn-off time | 5 | µs |
Typical switching performance @ 25°C
Current [mA] | Turn ON time [µs] | Turn OFF time [µs] |
---|---|---|
0.5 | 2.0 | 4.8 |
1.0 | 2.0 | 3.9 |
4.0 | 2.2 | 3.3 |
10 | 2.3 | 2.7 |
40 | 2.3 | 2.7 |
100 | 2.3 | 2.7 |
Isolation characteristics
Parameter | Value |
---|---|
Isolation grade | Functional |
Max. DC voltage | 250 V |
Max. AC voltage | 170 VRMS |
The functional isolation is only for the circuit technical protection. It does not provide an isolation that can protect a human being from electrical shock!
Logical map
The state of the output port is determined as follows:
Logical State | Output port state |
---|---|
HIGH | The contact switch is closed (ON) |
LOW | The contact switch is open (OFF) |
Compatible loads
The following loads are compatible with the isolated contact output ports:
● | Any load within the 30 V / 100 mA envelope is accepted. The power originates from an external power source or alternatively from the power delivered through the 12 V and GND pins of the I/O connectors. |
