IMPACT67 Pro EtherNet/IP IO-Link Master – 8 Ports (Art. No. 54631)
The Murrelektronik IMPACT67 Pro E DIO8 IOL8 M12L 5P is an IP67 EtherNet/IP compact I/O module in a fully potted plastic housing. Its eight M12 ports work as IO-Link masters (IO-Link V1.1, Port Class A and B) or as digital inputs and outputs, so IO-Link devices, sensors and actuators connect directly in the field. Power is supplied through M12 L-coded 5-pole connectors, and the network connects through two M12 D-coded Ethernet ports.
Key Features:
- 8 IO-Link Master Ports: IO-Link V1.1, Port Class A and B, COM1/COM2/COM3 with automatic baud rate detection, 32 byte process data in and out
- Digital I/O: PNP inputs for 3-wire sensors, mechanical switches and IO-Link devices; outputs up to 2 A per pin and 4 A per port
- EtherNet/IP: CIP Sync, Device Level Ring (DLR) and multiple connections; Composite Test Revision CT16
- Easy Addressing: BOOTP, DHCP or DIP switch, plus an integrated web interface
- IT Integration: OPC UA (UA TCP, Binary Encoding, Secure Conversation) and JSON via REST-API and MQTT
- High Power Capacity: 24 V DC US and UA, up to 16 A each, via M12 L-coded connectors
- Rugged: IP67, fully potted housing, -40 to +70 °C operating temperature
- Drop-In Mounting: mounting compatible with Murrelektronik MVK series I/O modules
Diagnostics:
- Diagnostics per module and per channel, via LED and via the bus
- Actuator warning per channel; cable break detection per port
- Current monitoring, voltage monitoring and temperature control
- IO-Link events for undervoltage supply and no voltage
- LED display of Ethernet connection and data traffic
