Industrial relay module with Modbus RTU
This eight-channel relay module handles up to 30 A per channel and communicates over RS485 using the Modbus RTU protocol. It is built for industrial automation cabinets that need reliable high-current switching under direct digital control.
Digital input expands local control
The integrated digital input lets the module accept on-site switch signals without an extra PLC input card. This reduces wiring and cabinet space for systems that mix remote Modbus commands with local safety or override switches.

Questions about this item
Will the relay contacts need replacement after many switching cycles?
The module uses 30 A rated relays; contact life depends on load type and switching frequency, so plan inspection intervals based on your actual duty cycle.
What thermal limit appears first during continuous 30 A operation?
Sustained 30 A per channel heats the relay contacts and PCB traces; adequate enclosure ventilation is required to keep temperatures within the relay's rated limits.
