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.

20-screw Barrier style and Euro style terminal blocks are available

for use with all ControlEdge HC900 I/O Modules.

Red terminal blocks are used for high voltage connections

for added safety while black terminal blocks are used for low voltage connections.

A 36-terminal Euro style block is available with the 16 AI, the 8 and 16 AO

as well as the 32 DC DI and 32 DC DO module types.
