97-4698 REV.A H0NEYWELL Control module
Overview
The Honeywell ControlEdge HC900 Controller is an
advanced loop and logic controller offering a modular design
sized to satisfy the control and data acquisition needs of a
wide range of process equipment.
I/O Modules
The following I/O modules are available to create a custom
control solution.
16 Channel Universal IO Module Galavanically isolated
Input/Output to chassis (p.27)
8-point universal analog input modules: Galvanic
isolation point to chassis inputs may be mixed on a
module and may include multiple thermocouple types,
RTDs, ohms, voltage or mill voltage types – all easily
assigned using the Process Control Designer
configuration tool. High point-to-point galvanic isolation
simplifies installation and saves the expense of external
isolation hardware (p.6).
16-point high level analog input module: each point is
configurable for V or mA. Galvanically isolated point to
chassis. Galvanically isolated point to point (p.10). 250
ohm shunt resistors can be added per channel.
4-point galvanically isolated analog output module.
Galvanically isolated point to chassis supports from 0 to
20mA each (p.12).
8-point analog output, galvanically isolated in 2 groups
of 4 points. Galvanically isolated point to chassis.
Supports from 0 to 20mA each (p.13).
16-point analog output, galvanically isolated in 4 groups
of 4 points. Galvanically isolated point to chassis.
Supports from 0 to 20mA each (p.14).
16-point digital input modules: Contact closure type, DC
Voltage, AC Voltage and AC/DC voltage types (p.15).
Galvanically isolated in groups of 8 channel to chassis
32-point digital input module: DC voltage. Galvanically
isolated point to chassis. Galvanically isolated in 2
groups of 16 points (p.1915).
8-point AC or 16-point DC digital output modules
(sinking type). Galvanically isolated point to chassis.
Galvanically isolated in 2 groups of 8 points (p.18).
32-point digital output: DC voltage (sourcing type).
Galvanically isolated point to chassis. Galvanically
isolated in 2 groups of 16 points (p.23).
8-point relay output module: four form C type and four
form A type relays. Galvanically isolated point to
chassis. Galvanically isolated relay to relay (p.20).
4 channel Pulse/Frequency/Quadrature I/O module.
Galvanically isolated point to chassis (p.24).
Insert and Removal of I/O under Power
For ease of maintenance, the ControlEdge HC900 controller
supports removing and inserting I/O modules from the
module rack without removing power from the controller.
Each module is sensed for validity by the controller
and auto-configured on insertion.
Other Modules
In addition to I/O, the following modules are available.
Scanner 1 module, single port (p.31)
Scanner 2 Module, dual port (p.32)
Universal AC Power Supply, 60W (p.4)
Power Supply 24VDC, 60W (p.4)
Redundant Switch Module (p.33)
Power Status Module (p.33)
Failsafe
All ControlEdge 900 Platform I/O modules support a user
specified failsafe value (analog) or state (digital) that the
module outputs or inputs will assume if communication
between the controller and the module is interrupted. Output
modules are also disabled if the controller fails to start.
Module diagnostics are not initiated if the control strategy
does not call for the inputs or outputs on the modules to
execute.
Failsafe is restricted to de-energize in safety applications.
