Isolated Output Simplified schematic

The output port implements an isolated contact output.

DC characteristics

Parameter	Conditions	Min.	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.	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 V_RMS

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.
