5.3.3 MOD1.20 - 16DO/8DI
5.3.3.1 Digital Outputs
The MOD1.20 has 16 own isolated and protected digital outputs. The digital output circuit must be powered
externally by a 24 Vdc power supply connected to the V+ (pins 1 and 11) and COM (pins 2 and 12) of the I/O
connectors, as shown in
Figure 5.3 on page 5-7 .
The outputs are PNP (activate the load connected to the negative of the power supply) and can supply a current
of up to 500 mA each. The description of each pin can be found on
Table 5.3 on page 5-7 .
In the example of Figure 5.3 on page 5-7 , outputs DO1, DO3, DO5, DO9, DO11 and DO12 are activated.
5.3.3.2 Digital Inputs
The MOD1.20 has 8 isolated digital inputs that must be excited by an external 24 Vdc power supply. The inputs
are bidirectional, which means the input common can be connected to either the negative or the Vdc of the power
supply (PNP or NPN).
The input activation levels are 10 to 28.8 Vdc for high level and below 3 Vdc for low level.
Table 5.3 on page 5-7 contains the name and function of each of the pins for the Digital Input and Output
connectors.
For those connectors, use AWG 30-16 cables.
