1 CANBUS I/O EXPANSION MODULE MODELS 56 / 56P FEATURES Eighteen multi-purpose I/O pins provide simple, flexible vehicle control system expansion. Two high-frequency (A, A) PWM driver outputs support a variety of vehicle system loads (i. e. horn, buzzer, relays). Five analog inputs which can be enabled for voltage or resistance measurement, supporting a variety of sensor and voltage inputs. Quadrature encoder input provides rotation and directional sensing. V unregulated and +5V regulated power supplies (00mA total) support low current control loads (electronic throttles) as well as sensing based loads (resistive senders, encoders). Serial port option allows direct access by Curtis / programming tools, Curtis Model 80 Display or status LED configuration. Configurable CANbus connection provides communication with other CANbus enabled devices. Multi-purpose I/O pins in a compact, low cost, PCB based module. Short circuit protection on all output drivers limits potential for load, device circuit damage. The Curtis Model 56/56P CANbus I/O expansion module provides accurate control of up to 5 fingertip joysticks, or can be used to add additional digital and analog I/O to any CANopen* based control system. It is available as a conformally coated PCB (model 56) or in an epoxy filled enclosure (56P). APPLICATION Expands I/O capabilities on any CANopen* vehicle control system. Typically used on materials handling trucks, aerial lift platforms, airport ground support equipment, compact construction equipment and sweeper-scrubber floor care machines. *Contact your local Curtis sales office for SAE J99 support options. Analog inputs can also be used as virtual digital inputs with programmable On/Off thresholds and variable filters. Built-in programmable dither amount & frequency allow precise hydraulic proportional valve positioning. All outputs can also be used as active high digital inputs. Constant current or constant voltage output modes provide accurate control. Built-in coil fly-back diodes reduce voltage spikes when driving inductive loads/coils. Compact PCB design 00 X 70 mm overall size or epoxy filled enclosure, pin & pin Molex connectors. PCB version must be mounted within a protective enclosure. PCB is conformally coated for protection from moisture and dust. Epoxy enclosed model 56P mechanically sealed to IP65. IP65 rating does not apply to Molex connectors. Optional status LEDs provides immediate, visual status of vital system functions. Support of 6V or 6 80V nominal supply voltages. 6V models are suitable for use on internal combustion engine applications.
