Any I/O slot in any rack (Controller or I/O expansion) can accommodate any
module type available for use in the HC900 system. Also, racks can
accommodate any mix of modules within constraints regarding power
availability.
Power supplies are identical for all racks.
Scanner modules are identical for IO Expander racks(C50 CPU only).
Every module has the same 20-pin (inline) connector on the printed wiring
board, that mates with either style of wiring terminal board available for the
HC900.
Two types are available: 20-connector barrier strip or 20-connector "Euro"
style. Both styles fit any type of I/O module available for the HC900 System.
Blocks have color code: red block, with tin plating on terminals for higher
voltages, and black with gold plating for lower voltages. Coding system
applies to both block types.
Key matches module to connector, ensuring correct board replacement
Every terminal board assembly includes a hinged door that accommodates a
color-coded, pre-printed label. Eight label types are available (label type per
I/O module type).
All I/O modules include microcontrollers for handling communications with the
Controller Module, and for performing and reporting diagnostics
All I/O modules include an integrated set of light pipes on the back of the
circuit board that convey:
- Status of the module (Tri-color)
- for digital modules, activity status of each channel (in green)
All modules include a metal cover that protects the front of the board. The
metal cover includes a formed-in loop at front for module extraction.
Standard. Modules are automatically sensed and configured on insertion.
Field power shall be disconnected before removing terminal blocks.
