The Honeywell ControlEdge HC900 900G02-0001 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.
The following I/O modules are available to create a custom control solution.
• 16 Channel Universal IO Module Galavanically isolated Input/Output to chassis .• 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.
• 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. 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.
• 8-point analog output, galvanically isolated in 2 groups of 4 points. Galvanically isolated point to chassis. Supports from 0 to 20mA each.
• 16-point analog output, galvanically isolated in 4 groups of 4 points. Galvanically isolated point to chassis. Supports from 0 to 20mA each.
• 16-point digital input modules: Contact closure type, DC Voltage, AC Voltage and AC/DC voltage types. Galvanically isolated in groups of 8 channel to chassis.
Insert and Removal of I/O under Power
For ease of maintenance, the ControlEdge HC900 900G02-0001 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.
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.
