Kingfisher Plus+ Hardware Manual
The IO-5 provides two signal ranges, 0 to 20 mA and 4 to
20 mA. The default range is 4 - 20 mA. A link on the rear
of the module selects 4 - 20 mA (link installed) or
0 - 20 mA I/O for all channels.
Digital Inputs
For high speed isolated digital inputs are provided on the module. All four digital inputs share
on one common rail.
All channels can be configured as pulse counters that appear 16 bit unsigned integer values
in the analogue 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-11/12/21 and PC-1 processors (Toolbox 32). All four channels can be used as pulse
counters when used with CP-30 processor module (Toolbox PLUS+).
Input characteristics are compatible with a wide range of user supplied input devices, such
as push buttons, limit switches, Hall sensors, proximity switches, etc.
Digital Outputs
The IO-5 provides 4 open-drain (sinking) outputs for controlling various loads. Power for the
loads can be provided from the on-board isolated +24 V
DC
power supply or from an external
power source.
The IO-5 output channels provide continuous protection from overloads.
