Expanding the iba system with I/O modules of the 750 series from WAGO/Beckhoff

Modul Types

The following I/O module types are supported:

• analog and digital I/O modules
• incremental encoders
• SSI inputs
• RTDs
• thermocouples
• measuring bridges
• modules for power measurement.

Coupling to K-bus

A maximum data volume of 2048 bytes can be transferred via the K-bus. The sampling rate depends on the cycle time on the K-bus.

Connection via fiber optics or Ethernet

There are two ways of simply integrating the I/O modules into the iba system with automatic detection (plug & play): on the one hand via a standard Ethernet connection with the central unit ibaW-750, on the other hand via fiber optics (FO) with ibaNet750-BM-D. The two variants differ mainly with regard to the possible sampling rates, the necessary cabling and the operating distance.

Measure power, calculate characteristics

ibaW-750 also supports various modules for power measurement of the 750-494 and 750-495 series. The modules measure current and associated voltages in the three-phase supply network and calculate characteristic values, e.g.

• effective/reactive/ apparent power
• effective/reactive/ apparent energy
• power factor
• phase angle
• frequency

The power measurement modules are particularly suitable for acquiring power characteristics in the low-voltage range directly at consumers. In addition, simple, but not standard-compliant grid analyses can be carried out on consumers. The Power Quality Unit ibaPQU-S is available for a standard-compliant measurement of the power quality.

Easy configuration, automatic detection

Both central units can be easily configured in ibaPDA as usual. The devices including the connected I/O modules are automatically detected in ibaPDA. When using ibaW-750, the device and the ibaPDA computer must be in the same LAN.

Comfortable configuration in ibaPDA

The power measurement modules are comfortably configured in ibaPDA. In addition, a large number of diagnostic signals are available, which can trigger an alarm in ibaPDA if, for example, a preset limit value is exceeded or not reached.
