EtherCAT Relay IO Module from KEB

Jake Wattenphul | August 9th, 2017


The EtherCAT Relay IO Module is the newest addition to the KEB Automation catalog of products. The Relay IO module combines a pilot relay with an IO module, providing the functions of two blocks on a DIN rail in the space of one. At only 25mm wide, the Relay IO module is a great space-saver in any installation cabinet.


The module is used to interface with both 120 volt and 230 volt AC field wiring. Typically a power contactor is signaled by a pilot or control relay. Traditionally the pilot relay is connected to an I/O module which then receives signals from a push-button, a sensor, or via the PLC. The signal going through the pilot relay will trigger the contactor to turn the load on and off. KEB’s relay module combines the function of an I/O module and DIN-mounted pilot relay.


When multiple loads are required you save significant space on the DIN rail by removing pilot relays and consolidating up to eight loads into a single module. Similar to other KEB I/O blocks the relay module measures only 25mm wide and has pluggable connectors. It is DIN rail-mounted and mechanically locks into other modules for a secure connection.


The I/O signals communicate from the C6 Smart to the relay module through a high-speed EtherCAT backbone. KEB’s EtherCAT relay module features eight Form A normally open contacts. The contacts are rated two amps each for inductive loads and five amps each for resistive loads.


The relay module is UL-listed and available for immediate sale.
