CompactBlock LDX I/O blocks are available as either base blocks or expansion blocks. Base blocks contain a maximum of 32 digital or 4 analog I/O, as well as a built-in DeviceNet or PROFIBUS DP network adapter. Thermocouple and RTD base blocks are also available.
CompactBlock LDX I/O expansion blocks contain 16 digital I/O and connect to a base block or another expansion block through a ribbon cable. An expansion block cannot be used alone.
The digital base modules support up to 3 digital expansion modules and up to 80 points of I/O for the DeviceNet network and 64 points of I/O for the PROFIBUS DP network. The analog base modules, both current and voltage, support two additional modules of up to 32 points of digital I/O. The RTD and thermocouple base modules do not support any expansion.
The wide variety of base and expansion combinations lets you eliminate unnecessary I/O points. In addition, CompactBlock LDX I/O modules, including digital (24V DC , 120V AC , and relay), analog (current and voltage), and temperature (resistance temperature detector and thermocouple), are compatible with a variety of sensors.
The DeviceNet network supplies power to DeviceNet base blocks and expansion blocks. A separate external 24V DC power supply is required for PROFIBUS DP base blocks and expansion blocks. Inputs and outputs are powered by an external 24V DC source that is independent of the network.
CompactBlock LDX I/O blocks are available with either D-shell or screw terminal I/O connectors. The blocks can be mounted on a panel or DIN rail in virtually any orientation.
