Efficient transport of signals
I/O blocks from Balluff connect discrete I/O and analog sensors and actuators to the control level via a fieldbus or network. The number of lines is substantially reduced by the use of the blocks.
Moreover, I/O blocks offer additional functions for signal preprocessing and expanded diagnostic options. Different designs and connection techniques enable solutions for a wide variety of applications, even under the most extreme environmental conditions.
Our I/O modules with their robust housings are suitable for use in a harsh industrial environment. The I/O hubs are based on M12 or M8 plug connections and are easy and economical to install and maintain.
The port-specific single-channel monitoring detects short circuit and overload as well as a cable break at the port. This degree of selective diagnosis is unique among I/O modules.
Our configurable I/O hubs variant BNI IOL-302…offers the highest functionality with the best flexibility. It combines two modules into one. Its maximum sensor load current of 500 mA is best suited for the operation of sensors with high current consumption. If configured as an output, up to 2 A is available at the port. This is ideal for the use of hydraulic valves with a high consumption level.
Balluff I/O hubs offer unique ability to expand I/O using the Balluff expansion port on the I/O hubs. This port can either be used as a standard dual channel I/O port or can be expanded with the same type of hub once over - perfect solution for optimizing the machine design by reducing number of network nodes and cables.
You can use the advantages of IO-Link even for the valve banks you are currently employing. Balluff offers a comprehensive portfolio of valve connectors with IO-Link connection.
The portfolio includes a D-sub connector, M23 connector as well as simply flying leads options for custom valve terminals. For example when using the D-sub (25-pin) connector, It is the same connector that connects to the valve bank, on the other end though, is simply a 4-pin M12 connector that connects to the IO-Link master port.
These valve connectors are IO-Link devices distributing signals to the individual coils. These IO-Link devices drastically reduce labor work for wiring the valve connector and promise error free installation. Additionally, it offers diagnostics for open coil or short circuit.
