Performance Parameters​

Bus update cycle matches the robot or motion controller communication timing

Channel-level fault indication supports maintenance diagnosis

Input filtering and output driving are optimized for 24 VDC industrial signals

Short-circuit protection limits damage during wiring faults

Material Composition​

Housing: flame-retardant ABS plastic

Internal circuit: industrial-grade multilayer PCB

Terminals: spring-clamp or screw-type terminal block according to configuration

Connectors: bus input and bus output industrial interfaces

Structural Characteristics​

DIN-rail mounting form factor for control cabinet installation

Front-face LED indicators for each I/O channel

Separate bus-in and bus-out connectors for daisy-chain topology

Dedicated 24 VDC power terminal group

Clearly separated input and output wiring areas

Working Principle​

Field digital sensors send on/off signals to the input circuits. The module transmits input status over the dedicated motion bus to the main controller. The controller returns output commands through the same bus, and the output stage switches actuators such as relays, solenoids, indicators and robot peripheral devices.

Installation Requirements​

Mount on a standard DIN rail inside a ventilated control cabinet

Use 24 VDC power supply with correct polarity and adequate current rating

Connect bus-in and bus-out cables with shielded industrial cable

Keep clearance around the module for natural convection cooling

Set node or address parameters according to the controller I/O configuration

Usage Notes​

Do not exceed the rated current of each output channel

Keep humidity non-condensing to avoid internal circuit damage

Separate signal cables from high-power motor drive cables

Verify bus node address before applying power

Inspect terminal tightness and LED status during commissioning
