IO-5 Combination Analog Digital I/O Module – 8 Input/5 Output
Features:
The combination analog/digital I/O module provides:
- 4 x AI Analog inputs
- 1 x AO Analog output
- 4 x DI Digital input / 10 KHz counters
- 4 x DO Digital outputs (solid state sinking)
Analog I/O
This module provides two signal ranges, 0 to 20mA and 4 to 20mA. The default range is 4-20mA. A link on the rear of the module selects 4-20mA (link installed) or 0-20mA I/O for all channels.
This module provides two signal ranges, 0 to 20mA and 4 to 20mA. The default range is 4-20mA. A link on the rear of the module selects 4-20mA (link installed) or 0-20mA I/O for all channels.
Resolution of the converted signals is 12 bits binary (1 part in 4096). The sign bit is not used in the conversion process. All channels are updated four times per second.
All inputs share a single common and all outputs share a separate common at the zero volt rail.
Input protection for the module is sufficient to guarantee operation with reduced performance with up to 1500V common-mode. The module provides electrical isolation of externally generated noise between field wiring and the backplane through the use of optical isolation.
Digital I/O
Input characteristics are compatible with a wide range of user supplied input devices, such as push buttons, limit switches and electronic proximity switches, while outputs can control a wide range of user supplied load devices such as: motor starters, solenoids and indicators.
All four Digital Inputs share one common rail. All channels can be configured as pulse counters that appear as 16-bit unsigned integer values in the analog input registers of the RTU processor module. Because of processor module limitations, only channels 1 and 2 can be configured as pulse counters when used with the CP-11 and PC-1 processors (Toolbox32). All four channels can be used as pulse counters when used with CP-30 processor module (Toolbox PLUS+).
Four isolated Digital Outputs are provided on the module. All four Digital Outputs share one common rail. Solid state output switches are protected from over-currents and shorts and also from overheating. Digital Outputs can control a wide range of loads such as: motor starters, solenoids, indicators, etc. The user must supply the DC power to operate field devices.
