Digital input EPP1518 Digital input | 24 V DC, counter EtherCAT Box 298 Pulses often need to be captured in technical control applications. This can be done with fast inputs such as the EPP1018 and a central pulse counter. If the pulse length is the order of magnitude of the control cycle time or less, the controller cannot record these signals correctly any more. Pre-processing counter modules can then be used to count the number and direction of the pulses, which enables the controller to determine reliable values. The counter is adapted to the individual requirements, such as up/down counter or Gate/Latch-controlled, by fieldbus parameterisation. With a counting depth of 32 bit any overflow can be controlled reliably, even at high frequencies. The multi-functional EPP1518 EtherCAT P Box supports the following operating modes: – 1 x 32 bit up/down counter (the counting direction is specified via the input) – 1 x 32 bit gated counter (the counter is enabled via the input) – 2 x 32 bit forward counter (no direction detection) 2-channel up/down counter 24 V DC, 1 kHz, 32 bit, adjustable input filters 0…100 ms, M12 Technical data EPP1518-0002 Connection technology M12, screw type Specification EN 61131-2, type 1/3 Input filter adjustable 0…100 ms Number of inputs 8, 2 of which can be used as 32 bit up/down counters B 2 3 B A 1 4 5 A 3-wire 2-wire +60 °C -25 °C Nominal voltage 24 V DC (-15 %/+20 %) Counting frequency Protocol Bus interface Distributed clocks Sensor supply Current consumption max. 1 kHz EtherCAT 2 x M8 socket, shielded, screw type, EtherCAT-P-coded yes from control voltage, max. 0.5 A per 4 sensors, short-circuit proof typ. 100 mA from US Electrical isolation 500 V Special features adjustable filters Operating temperature -25…+60 °C Approvals CE, UL in preparation Further information www.beckhoff.com/EPP1518 We reserve the right to make technical changes.
