Ethernet/IP I/O modules
Belden Inc. has released Ethernet/IP modules that can connect to discrete wiring devices via 16 digital I/O channels with universal input/output or input functionality
Belden Inc. (NYSE:BDC) introduced EtherNet/IP I/O modules facilitating the connection of discrete wiring devices (sensor/actuators) via 16 digital I/O channels with universal input/output or input functionality directly to industrial controllers.
These EtherNet/IP modules are available with 16 universal user-selectable digital inputs/outputs (0980 ESL 710) or 16 dedicated inputs (0980 ESL 711). The easy diagnostic concept helps to find the exact location of any faults for each I/O port with “on-board” LED diagnostic indicators. Access to this information is also available via the EtherNet/IP network: making it possible to evaluate the details on a centralized operating and display system, such as a Human Machine Interface (HMI), without having to configure the module.
Both modules fully support ODVA’s Device Level Ring (DLR) standard, enabling multi-port EtherNet/IP devices to operate in a ring or linear topology. DLR insures that a single-point failure does not prevent communication between the remainder of the functioning devices. The integrated switch allows both ring and line (daisy chain) topology. A substantial cost saving can be obtained as external switches are not needed.
Due to a rugged housing and IP67 terminations, these EtherNet/IP modules require no protective enclosure and can be mounted on machines. Operational temperatures are -10 C to +60 C; and 24 V dc (11-30 V dc) power input is through standardized 7/8-in. 4-pole power connectors. Network addressing is via rotary switches, BOOTP or DHCP.
