Electronic modules series 750 WAGO
Digital output module DO – 2 and 4 channel; short-circuit protected; high-side switching
The connected load is switched via the
digital output from the control system.
All outputs are electronically short-circuit
protected. All digital output modules
operate with any of the eldbuses.
Power connections are made
automatically from module to module
when snapped onto the DIN rail.
No. of outputs
2 or 4
Current consumption
7 or 15 mA
Type of load
Resistive, inductive, lamps
Output current
0.5 A; 2 A
(2 channels)
0.5 A (4 channels)
Current consumption
15 mA or 30 mA + load
(eld side)
Internal bit width
2 or 4
Analog input module AI – 2 and 4 channel; 4–20 mA and 0–10 V; single ended
The analog input module receives
signals with the standardized values of
0–10 V, 4–20 mA. The 4–20 mA input
module can also supply the voltage
for 2-wire transmitter. The input signal
is electrically insulated and will be
transmitted with a resolution of 12 bits.
The shield (screen) is directly connected
to the DIN rail.
RTD and TC inputs on request.
No. of inputs
2 or 4
Voltage supply
Via system voltage
(DC/DC)
Current consumption
60 mA typ. (10 V versions)
75 mA (20 mA versions)
Maximum input voltage
35 V
Signal inputs
0–10 V, 4–20 mA
Internal resistance
130 or 133 k Ω
(10 V versions)
Input resistance
220 or 270 k Ω (20 mA versions)
Resolution
12 bits
Conversion time
2 ms typ.
Internal bit width
2 x 16 bits data
2 x 8 bits control/status
Analog output module AO – 2 channel; 4–20 mA and 0–10 V
The analog output module creates a
standardized signal of 0–10 V, 4–20
mA.
The output signal is electrically insulated
and will be transmitted with a resolution
of 12 bits.
Current analog output modules use
power derived from the eld side
(loop powered), Voltage analog output
modules use the internal system supply.
No. of outputs
2
Current consumption
65 mA
(internal, 10 V versions)
60 mA max. (internal, 20 mA versions)
Output signals
0–10 V, 4–20 mA
Load impedance
>5 k Ω
(10 V versions)
<500 Ω (20 mA versions)
Resolution
12 bits
Internal bit width
2 x 16 bits data
2 x 8 bits control/status
Accessory modules (others on request)
Supply module, passive 24 V DC End module
The supply module provides I/O module power
through the power jumper contacts.
Maximum current supply to all connected
modules is 10 A.
In connection with the system conguration, it
is important to assure that this current is not
exceeded. Should higher currents be necessary,
intermediate supply modules must be added to
the assembly.
After the eldbus node is assembled with the correct
eldbus module and selected I/O modules, the ”end”
module is snapped onto the assembly. It completes the
internal data circuit and ensures correct data ow.
One is required for each eldbus module.
