Connecting The 8X Input/Output Modules; Connecting The Output Module Load Supply - Emerson AVENTICS CMS B Instrucciones De Servicio

Dangerous voltages
A power pack without safe isolation may lead to dangerous voltages in the
event of a malfunction. Injuries from electric shock and system damage may
be the consequences.
Only use a power pack with safe isolation according to EN60747, VDE 0551
u
classification! The corresponding electrical circuits are thus SELV/PELV cir-
cuits in accordance with IEC 60364-4-41.
To connect the bus coupler load supply:
1. Set up the correct pin assignment on the plug connections if you do not use
pre-assembled cables. See g Table 5.
2. Connect the bus coupler operating voltages using the electrical connector.
See section g 11. Spare parts and accessories.
3. Check the operating voltage specifications using the electrical characteristics
and comply with them. See section g 10. Technical data.
4. Provide power according to g Table 6. Select the cable cross-section accord-
ing to the cable length and occurring currents.

6.3.4 Connecting the 8x input/output modules

Freely accessible conductive parts
Risk of electric shock on contact!
When connecting peripheral devices (I/O interface), observe the require-
u
ments to protect against accidental contact in accordance with EN 50178,
classification VDE 0160.
Input module
1. Wire the inputs (DI8_M8) or (DI8_M12). See g Table 10 and g Table 9.
2. Connect the electrical inputs/outputs to the I/O modules with M8 or M12 cou-
pling plugs (accessories).
3. To ensure the IP65 protection class, close unused sockets with M8 or M12
protective caps (accessories).
The total current for all sensor supplies (pin 1) on one valve system
must not exceed 0.7 A.

Output module
1. Wire the outputs (DO8_M8) or (DO8_M12). See g Table 8 and g Table 7.
2. Connect the electrical inputs/outputs to the I/O modules with M8 or M12 cou-
pling plugs (accessories).
3. To ensure the IP65 protection class, close unused sockets with M8 or M12
protective caps (accessories).

Total current is too high
Every output is supplied with a continuous current of max. 0.5 A. Current loads
over 0.5 A per output can damage the system.
Make sure that the current load of 0.5 A per output is not exceeded.

6.3.5 Connecting the output module load supply

Each output module has its own M12 connection for the load supply. Each of the
4 outputs are supplied via the load supply. The U
cally isolated.
The connection cable for the output module load supply must meet the following
requirements:
• Cable socket: M12x1, 4-pin, A-coded without center hole (to ensure correct
plug-in connection)
• Cable cross section: > 0.5 mm
• Length: Max. 20 m
1. Set up the correct pin assignment on the plug connections if you do not use
pre-assembled cables.
2. Connect the load supply using the M12 plug.
