1: Overview - Curtis 1353 User Manual

Return to TOC
The Curtis 1353 is a CANopen interface module with hydraulic system oriented functions, inputs,
and outputs. It provides simple, flexible, and cost-effective control of up to nine proportional or on/
off hydraulic valves. It can be used on internal combustion engines and electric vehicles.
The 1353 can extend the I/O capabilities of the Curtis VCL-driven system and enhance the systems
that use Curtis AC controllers by providing additional I/O. Although the 1353 has specific features
orienting it towards hydraulic valve control, the I/O and firmware are designed to give it the flexibility
to be used in many generic applications, such as Mobile Elevating Work Platforms (MEWPs) and
aerial lifts.
The housing is designed to meet the difficult environment seen in material handling and outdoor
equipment. This water-tight design can survive high shock, vibration, freezing, and dust. One section
of the housing is aluminum which allows a simple method for heat-sinking the internal drivers.

Features include:
• 9 high-frequency output drivers, which can also be used as active-high digital inputs.
• Closed loop constant current, constant voltage, or direct PWM control on each output.
• Built-in programmable dither control for hydraulic valves.
• Min/Max current and Ramp up/down time setting for driver outputs.
• Built-in coil flyback diodes.
• 6 analog inputs (0–15V), which can also be used as virtual digital inputs.
