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.
