OUTPUT WIRINGS

NOTE: shielded cables are recommended for inputs and outputs wiring.

Output on/off 1250Hz



Opto-insulated output with collector and emitter

terminals floating and freely connectable



Maximum switching voltage: 40V



Maximum switching current: 100mA



Maximum saturation voltage between collector

and emitter @100mA: 1.2V



Maximum switching frequency (load on the

collector or emitter, RL=470

Ω

, VOUT=24V

1250Hz



Maximum reverse current bearable on the input

during and accidental polarity reversion (VEC):

100mA



Insulation from other secondary circuits: 500V



Opto-insulated output



Maximum load 1000Ω



Maximum voltage without load 27V



Refresh frequency equal to the sample frequency

of the connected sensor



Protected against persistent over voltages up to

30V



Opto-insualted output with collector and emitter terminals

floating and freely connectable. In order to get the

maximum speed performances it is necessary to connect

the emitter to the common terminal of the outputs (0V),

while the load has to be on the collector. This output is

internally connected to the power supply source 24V

available on the terminal block.



Maximum switching voltage: 40V



Maximum switching current: 100mA



Maximum saturation voltage between collector and emitter

100mA, load on the collector and internal power supply:

0.3V



Maximum saturation voltage between collector and emitter

100mA, load on the emitter and internal power supply: 3V



Maximum switching frequency, load on the collector and

internal power supply: (RL=470

Ω

, VOUT=24V

): 12500Hz



Maximum switching frequency, load on the emitter or

external power supply: (RL=470

Ω

, VOUT=24V

): 2500Hz



Insulation from the other secondary circuits (except 24V

and 4-20mA outputs): 500V

OUTPUT 1/2 standard - OUTPUT 3/4 with modules

Only with ME 201 module

Output on/off 12500 Hz

The converter detect a loss of load on the 4 to 20mA output; to disable this

function set the value "mA val. fault" to 0 (Pos. 4.6)

4-20mA output
