TRICONEX 9565-810 output circuit module

The qualification of the TRICONEX 9565-810 is based on a system design which connects Non-lE input/output circuits to modules installed in one or more separate chassis which are interfaced to the Class lE portion of the PLC by fiber optic cables (through Model 4200 and 4201 Remote RXM modules). This design provides electrical isolation of the Non-lE input/output circuits because the fiber optic cables are incapable of transmitting electrical faults. Based on this system design, only the communication modules, which can not be installed in fiber optically interfaced expansion chassis, are required to provide Class lE to Non-lE electrical isolation capability (if these module are used to interface to Non-lE communication equipment). 

The TUT was configured with TCM communication modules in Chassis I and 2. Each of these communication modules includes a MODBUS serial communication interface to simulated Non-i E equipment. The Chassis 2 TCM Module MODBUS serial communication interface was tested to demonstrate Class 1E to Non-IE electrical isolation capability. In addition, the TRICON vi0 Model  9565-810 relay output module was tested for electrical isolation capability. This allows interface to Non-lE circuits (such as alarms or annunciators) without having to install a separate, fiber-optically isolated chassis. A Model 9565-810 relay output module was installed in Chassis 3, Slot 5 of the TUT.
