I/O Module Installation and Wiring - Remote Termination Panel (RTP)

Remote Termination Panel (RTP)

The optional Remote Termination Panel (RTP) provides an easy way to connect the HC900 controller to the field wiring. The RTP integrates some of the typical externally connected components, reducing wiring and setup time. It also minimizes the need for multiple wires under a single screw connection by expanding the connectivity of the shared terminals of the I/O modules.

See Appendix B Installation of Remote Termination Panels (RTPs) for details.

Terminal Block-to-Field (Signal) Wiring

Although both of the two available terminal block styles can be used on all I/O module types, wiring methods vary with the module type and with the type of field devices connected to the terminal block. The descriptions that follow provide details.

Wiring can be routed through the terminal block at the top, at the bottom, or both. Wiring should be fixed in place using wire ties at the slotted tabs that are molded in at top and bottom of each terminal block.

Wiring Rules and Recommendations

In general, stranded copper wire should be used for non-thermocouple electrical connections. Twisted-pair wiring with shielded cable will improve noise immunity if wire routing is suspect.

Wire Gage

Observe all local codes when making power connections. Unless local electrical codes dictate otherwise, the recommended minimum wire size for connections is given in Table 12.

Routing and Securing Wires

Typically, field wiring is routed to connections at a terminal panel near the controller and then from the terminal panel to the terminal blocks on the I/O modules.

Whatever method of routing is used, wiring must be mechanically supported along its length, and must be protected from physical damage and electromagnetic (noise) interference. (Refer to Installation Planning, Environmental Considerations, in this manual.)

Also, all wires must be securely terminated, using appropriate wiring practices.
