5.3.4 MOD1.30 - 8DO/16DI
5.3.4.1 Digital Outputs
The MOD1.30 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+ (pin 1) and COM (pin 2) of the digital output connectors,
as shown in
Figure 5.4 on page 5-9 .
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 5.4 on page 5-9 .
In the example of Figure 5.4 on page 5-9 , outputs DO1, DO3 and DO5 are activated.
5.3.4.2 Digital Inputs
The MOD1.30 has 16 isolated digital inputs that must be excited by an external 24 Vdc source. The inputs are
bidirectional, which means the input common can be connected to either the negative or the Vdc of the power
supply.
Two common pins are available, one for DI9 to DI16, and the other for DI17 to DI24, thus allowing a group to be
connected to V+ and the other to the GND. This feature gives more flexibility to the project, since it allows both
PNP and NPN contacts of a device to be connected to the MOD1.30 inputs.
The input activation levels are 10 to 28.8 Vdc for high level and below 3 Vdc for low level.
Table 5.4 on page 5-9 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.
