Models XT1530 and XT1540 have been added to the BusWorks XT series of Ethernet I/O modules. Ethernet communication protocols offered are Modbus TCP/IP, i2o peer-to-peer, Ethernet/IP or Profinet. The XT1530 analog output ranges are 0-20 mA dc or 4-20 mA dc with discrete input range 0-32 Vdc TTL thresholds and discrete output 0-32 Vdc, open-source output. The XT1540 accepts analog voltage outputs of up to 10 Vdc and discrete inputs of 0-32 Vdc, TTL thresholds and 0-32 Vdc open-source output. They operate from -40 to 60 °C with noise immunity and surge protection, are high shock- and vibration-tested and are CE-compliant.
