4.1 DIGITAL OUTPUT LED
LEDs O01 to O24 represent outputs DO1 to DO24, respectively.
In the MOD1, the LEDs of the digital outputs light RED whenever the digital output is active, Figure 5.2 on page 5-5.
4.2 DIGITAL INPUT LED
LEDs I01 to I24 represent inputs DI1 to DI24, respectively.
The LEDs of the digital inputs are bicolor. They light RED if the digital input is activated through the positive of the
power supply, and the negative connected to the common of the inputs (PNP). They light GREEN if the positive
of the power supply is connected to the common of the inputs, and the negative of the power supply connected
to the respective input (NPN), Figure 5.1 on page 5-3.
4.3 RELAY OUTPUT LED
LEDs RL1 to RL6 of MOD7.00 represent, respectively, relays RL1 to RL6.
With the relays disabled, that is, with the NC contact closed and the NO contact open, the LEDs are off. When
a relay is enabled, that is, the NC contact opens and the NO contact closes, the LED representing this relay will
light GREEN; see Figure 5.1 on page 5-3.

5 ELECTRICAL INSTALLATION
The expansion boards are incorporated to the RUW100 in a simple and fast way, using the "Plug and Play" concept
by the user. When the RUW100 is powered up, the electronic circuit identifies the number of connected expansions,
the model and the firmware version of each one. They also receive an address according to the position of each
one, so that it is possible to access them through the communication bus.
ATTENTION!
Accessories must be installed or removed with the RUW100 de-energized to avoid burning
components and also to allow them to be identified.
5.1 GROUNDING
Use the screws indicated in Figure 2.1 on page 2-2 to ground the product. The screws are connected internally;
however, the connection of both ensures better grounding.
5.2 EXPANSION LIMITS
The WEG remote unit (RUW100) allows coupling up to 8 of the expansions described in this manual. However,
due to some characteristics of the modules, some limits have been defined for coupling some specific modules.
5.2.1 MOD3.00
The coupling of MOD3.00 expansions to the RUW100 is limited to two; however, other digital input/output, analog
input, thermocouple and load cell expansions can be coupled up to the limit of eight modules.
If there are two MOD3.00 expansions coupled, it is not possible to couple MOD7.00 expansions.
If there is only one MOD3.00 expansion coupled, it is possible to couple up to three MOD7.00 expansions, and it
is also possible to couple other expansion models up to the limit of the RUW100.
5.2.2 MOD7.00
The coupling of MOD7.00 expansions to the RUW100 is limited to five; however, other digital input/output, analog
input, thermocouple and load cell expansions can be coupled up to the limit of eight modules.
If there are five MOD7.00 expansions coupled, it is not possible to couple MOD3.00 expansions.
If there are three (or less) MOD7.00 expansions coupled, it is possible to couple a MOD3.00 expansion, and it is
also possible to couple other expansion models up to the limit of the RUW100.

5.3 MOD1.YZ - DIGITAL INPUTS / OUTPUTS
5.3.1 MOD1.00 - 24DIS
5.3.1.1 Digital Inputs
The MOD1.00 has 24 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.
Three common pins are available, one for DI1 to DI8, another for DI9 to DI16 and another 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 MOD1.00 inputs.
The input activation levels are 10 to 28.8 Vdc for high level and below 3 Vdc for low level.
The example of Figure 5.1 on page 5-3 shows inputs DI1, DI3, DI5, DI9 DI11 and DI13 activated by +24 V from
the power supply (PNP), and inputs DI17, DI21 and DI24 activated by the negative of the power supply (NPN).
Table 5.1 on page 5-3 contains the name and function of each of the pins of the Digital Input connectors.
For those connectors, use AWG 30-16 cables.

5.3.2 MOD1.10 - 24DOS
5.3.2.1 Digital Outputs
MOD1.10 has 24 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, 11 and 21) and COM (pins 2, 12 and 22) of the I/O connectors,
as shown in Figure 5.2 on page 5-5.
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.
Table 5.2 on page 5-5 displays the name and function of each of the Digital Output connector pins.
For that connector, use AWG 30-16 cables.
In the example below, outputs DO1, DO3, DO5, DO9, DO11, DO13, DO17, DO19 and DO21 are activated.
