The Hubbell Intelligent Radio Locomotive Systems features a microcomputer with status display and built-in diagnostics along with our high speed, digital, biphase modulation to provide reliable, efficient and economical operation of diesel-electric locomotives from a portable transmitter. Each radio control system operates on a licensed frequency in the 72– 76 MHz or the 450–470 MHz bands. The receiver is crystal controlled. A synthesized 72–76 MHz receiver is also available. Pneumatics Cabinet Benefits • Easy to Maintain — Self diagnostics identify problem areas via the status display. • Fast Response — High Speed data rate offers fast, responsive operation. • Frequency Conservation — Up to four systems can share the same radio frequency, which also saves on spare parts requirements. • Cost Reduction — Operating crew is reduced on each shift. Payback is realized in just a few months. • Better Visibility — Remote control takes the operator out of the cab providing him with improved visibility and total control from grade level. • Simple Operation — Portable, lightweight transmitter is easier to operate than manual controls. Midsize Transmitter (See Spec 31110) Hubbell 72 & 450 MHz Remote Control System for Locomotive Applications Receiver Cabinet By operating the transmitter switches, a radio message is sent to the locomotive mounted receiver to control the direction and speed of the locomotive. Additional data bits are available to perform special auxiliary functions such as sounding of horn, application of brakes or control of couplers. Microprocessor Radio Locomotive Control

System Features Secure Control — Hubbell’s biphase data transmission scheme and Cyclic Redundency Check code (CRC) prevent false motions and provides for controlled shutdowns. Digital messages are checked for address, format, and content before any motion or function is activated. While in motion, check circuits continuously monitor the received message and the quality of the RF carrier signal. Any error or loss of signal integrity will de-energize all controlled functions and apply the brakes. Frequency Conservation — It is possible to have several transmitters operating in the same area,...

comotive magnetics and pneumatic systems in response to decoded control commands. The configuration of the manual control switches is duplicated and wired to industrially rated terminals for interconnection to the locomotive controls. A manual-remote transfer switch is provided to completely isolate the radio system from the manual controllers. The receiver antenna is normally mounted on the locomotive cab, and sufficient co-axial cable is provided to connect the antenna to the radio receiver module in the cabinet. Pneumatic Cabinet The pneumatics enclosure is of NEMA 12 construction and...
