Multipurpose I/O module MVMIO24-CO-x

Product description

The multipurpose I/O module is designed for both stand-alone and networked applications. The module includes a wide variety of different types of I/O and the connections are all made with spring-loaded connectors enabling easy modification of systems prior and after installation. The module software is written in C, and the application can be written by either Axiomatic Technologies Oy or by customer. The standard application is a CANopen slave module application conforming to CiA draft standard DS-401 (device profile for I/O modules).

The basic configuration of the module includes 8 PNP inputs which can be changed to NPN types in groups of 4 (in ordering). The outputs have a current limitation of 3A / channel, and the outputs are also protected against short-circuit and overtemperature. The PWM outputs have a current measurement in each channel (12 bit resolution), and they are suited for driving proportional valves in range of 0...2000mA. Output polarity, ramps, dead band and current feedback controller parameters can all be configured by software.

The analog inputs are suited for VDO automotive sensors. These sensors are quite cheap, resistive sensors, which are a good solution for measuring for example temperatures of oil, coolant liquids, air, or other variables in automotive or hydraulic systems. The inputs can be factory-configured also for other input signals, like 4...20mA current signal.

The I/O module is designed for harsh environments. The module is mounted in an IP65-protected case, and IP67 rating is also available on request. The standard module has spring-loaded connectors inside the module case, which require no seperate external connectors for the wiring. The module can also be supplied with customer-specific connectors.

Power supply for the module can be on the range 9 - 28V. The module is protected against reverse battery connection, overvoltage, and load-dump situations.

I/O can be controlled either using RS-232 or CAN buses. A connector for RS-232 or CAN (or both) of desired type can be mounted on the case on request. The module is available with CANopen protocol. The CAN bus node id is changed through the RS-232 interface using normal terminal software. CAN bus termination can be switched on by using a jumper.

Applications

Typical applications include for example: mobile applications, vehicles, work machines cranes, elevators, robotics, material handling machines.
