The 2085sc-OF8 Expansion I/O module provides current and/or voltage outputs.
The module supports:
• Eight output channels. The module outputs either voltage or current
signals for each channel.
• Current output. When the module receives a new command value from
the output image, the module converts the digital value to an analog
current signal using a Digital to Analog Converter (DAC).
• Voltage output. When the module receives a new command value from
the output image, the module's circuitry converts the digital value to an
analog voltage signal using a Digital to Analog Converter (DAC).
• Output fault detection.
Range scaling of output data.
•
• Over or under voltage detection (from user-defined values).
• Four data formats.
All outputs have fault tolerance and ESD protection to avoid damage to circuitry
on the board. The modules use 50 VAC working Reinforced Insulation between
the output channels and the backplane. Individual channels are not isolated from
each other.
The 2085sc-OF8 module uses a 16-bit digital-to-analog converter to achieve a
16-bit resolution with ±10 V full scale ranges. The module also uses 8 separate
output drivers to provide for either current or voltage output signals on each
channel. Each output channel is individually configured via Rockwell-provided
Connected Component Workbench (CCW) software for Micro850 and Micro870
family controllers or with the Module Configuration Converter (MCC) utility
from Spectrum Controls, Inc.
The module is factory calibrated and tested before shipping. After installation,
the modules begin operation in a default, usable condition. During startup, all
outputs are disabled and off until a valid configuration has been received. Default
configuration is 4 to 20 mA.
The module normally requires no further user intervention. However, if the
module experiences a hard fault condition, you may need to cycle power.
