LLD-ModbusIO-01
The ModbusIO series provides 5 general module slots and 1 EXT expansion slot, so you can configure 9 ModIO function modules to match on-site point requirements — digital or analog signals, with a choice of resolutions. It uplinks over Modbus-RTU／TCP and supports LLD-DDC for programmable logic control.
Enclosure Version
Anodized, baked finish, 228 × 109 × 33 mm (incl. mounting flange)
Nameplate
Available with nameplate labeling
Product Highlights
Low-Power Compute Core
ST STM8L152R8 low-power microcontroller — fanless, suited to continuous operation.
AC/DC Power Input
Takes 24 V as either AC or DC, so whichever supply the site already has can be used directly.
DDC Programming & Tooling
Control logic is written in the ICDT graphical compiler and downloaded to the board; the same tool handles parameter setup and online debugging.
Modular I/O Expansion
Five general slots plus one EXT expansion slot take nine ModIO module types in any mix — a failed module is replaced on its own.
Environmental Tolerance
Runs continuously inside an unventilated control cabinet; clips onto a standard DIN rail for quick installation.
