Fig. 12 EXTERNAL SWITCH IN SERIES WITH THE INTERNAL
CONTACT
In this case it is recommended to install an additional RC
network across the external contact as show in Fig. 12
The value of capacitor (C) and resistor (R) are shown in the
following table.
Anyway the cable involved in relay output wiring must be as far
away as possible from input or communication cables.

Logic level 0
Logic level 0 Logic level 0 Logic level 0 Logic level 0: Vout < 0.5 V DC.
Logic level 1
Logic level 1 Logic level 1 Logic level 1 Logic level 1:
- 14 V + 20 % @ 20 mA
- 24 V + 20 % @ 1 mA.
Maximum current = 20 mA.
NOTE NOTE NOTE NOTE NOTE: This output is not isolated.
A double or reinforced insulation between instrument output and
power supply must be assured by the external solid state relay.
