Product Description
C9900-M974 is a Beckhoff accessory in the C9 PC Accessories series. It uses a shielded CAT.5 cable as its data medium to reduce electromagnetic interference during communication. The interface supports a data rate of 100 Mbit and permits an EtherCAT cable length of up to 100 m. Its EtherCAT connection is a four-pin, D-coded M12 socket, providing an industrial network connection.
The unit operates from a 24 V DC power supply. Its maximum current draw is 300 mA, and its maximum power draw is 7.2 W. The emergency-stop contact arrangement consists of one normally open contact and two normally closed contacts, supporting safety-circuit switching. The contacts operate between 5 V and 35 V AC/DC, with a minimum contact current of 1 mA AC/DC and a maximum contact current of 100 mA AC/DC. Maximum switching capacity is 250 mW, which limits the electrical load controlled by the contacts.
The IP65 protection class provides resistance to dust ingress and water jets when the unit is properly installed. Four M6 holes on the rear provide mounting points for securing the accessory.
