Engineering SpecSheet LongRT Base Unit (LBU) Features Rugged High-Impact Polymer Enclosure Real-Time Clock Field Upgradeable Removable Antenna Weatherproof Design The LongRT Base Unit (LBU) represents the next generation of Cervis configurable command and control machine-mounted units. Designed for safety, the LBU employs a dual processor architecture compliant with ISO 13849 Category 3 Pld. Versatile and configurable, the LBU enables complex command and control solutions in harsh environments and industrial applications. Specifications Max. Power Ratings Operating Voltage Reverse Voltage Protection Up to -40VDC Over Voltage Protection Operating Power Environment Operating Temp Storage Temp Humidity Analog Output (Two, M19 & M20) Voltage Range Drive Current Analog Input (Four, M21–M24) Voltage Range Input Impedance Available for application specific use Lit when message transmitted Lit when message received Lit when safety-link is active Blinks during normal operation Frequency Counters Serial Communications CAN Protocol Enclosure Dimensions Total Weight High-Side switch Output Protection Over current; under current; over temp. External, RP-TNC 50 port INPUT Type I Sense Threshold *1000Hz max. when a single channel is configured for PWM output. Increasing the number of PWM channels decreases the max. PWM frequency. ** For best performance, do not connect antenna directly to the base unit. Instead, Cervis recommends to use an extension cable with an antenna base plate mount.
