Core Features

1. 8 independent mechanical relay output channels, each channel supports wide-range load of 24~250V AC/DC, single channel maximum 3A continuous carrying capacity, can directly drive most on-site small industrial actuators.
2. Built-in channel-level surge suppression and isolation circuit, effectively suppress electromagnetic interference and voltage spike impact in thermal power, petrochemical, metallurgy harsh industrial workshop environment, avoid DCS main I/O module burnout caused by field short circuit.
3. Each channel is equipped with independent LED status indicator light, which intuitively displays relay pull-in and signal output status, convenient for maintenance personnel to quickly locate open circuit, short circuit and channel abnormal faults on site.
4. Standard dedicated connector docking design, plug and match with S800 series digital output I/O main module, no complicated wiring conversion, support hot plug maintenance without shutting down the entire remote station.

5. Adopts industrial flame-retardant PCB and detachable screw terminal block structure, convenient for field cable wiring, modification and later maintenance; good shock and vibration resistance, suitable for long-term stable operation of distributed field I/O stations.
