TIM, using your stuff as an example, you could easily show the PLC outputs on a sheet and to right or common/output give reference to any RUNG that uses that relay. That would add more pages but would eliminate a need to show interposing relays. A decent troubleshooter should easily understand that.

Why IRP Used for Interface Between DCS and MCC
IRP houses Interposing Relays. The reason for using interposing relays are: 1) To electrically isolate two systems with different voltage levels (e.g., DCS @ 24V, MCC @ 220Vdc, or 230Vac 0r 110Vdc). If there is any short circuit or any electrical disturbance at MCC side, Interposing Relays shall protect DCS from them and vice versa.

Interposing Relays: What Are They?
How Interposing Relays Work. Interposing relays operate by receiving a low-power signal from a control device, such as a PLC, and using it to control the switching of a higher-powered load. When the low-power signal is applied, the interposing relay''s contacts are energized, closing the circuit and allowing current to flow to the load.

6 FAQs about [Guernsey interposing relay cabinet]
What is an interposing relay?
Interposing_Relays_What_are_They.pdf An interposing relay is simply an auxiliary relay that is used to isolate two different systems or devices from one another. So why do we need to isolate different devices in the first place.
What is an interposing Relay Cabinet used for?
An interposing relay cabinet is usually installed in the Motor Control Centre for the purposes of starting/stopping/drive status and ESD of electrical drives in the Petroleum Industry. Interposing relays are commonly used to separate Electrical and Instrumentation systems.
What are interposing relay panels in industrial control?
Interposing relay panels in industrial control are used to communicate the signals and status between the Automation system such as DCS & PLC and electrical modules in Machine control centre (MCC) such as motor control units, motors, pumps, lamps, and so on.
How does a PLC interposing control relay work?
The interposing control relay is driven by the PLC. A N.O. contact of the interposing relay is then used to drive the coil of the large contactor. A circuit breaker is included as suggested in the PLC datasheet to minimize damage when something goes wrong. Figure 3: Wire diagram showing the PLC, interposing relay (CR 1), and contactor.
Can control relays be interposed?
It is worth noting that although control relays can be interposed for safety reasons, this is not synonymous with the category of devices called ' safety relays ' with redundant sets of input coils and contact sets which meet strict safety regulations, normally for motor and motion applications.
Why are relays used as interposing relays necessary?
Relays used as interposing relays are essential because the circuits being switched have voltages and/or currents which can't be accommodated by the driving relay. For example, if the relay of a PLC can only accommodate 0.5A at 220 VAC, but the solenoid which is to be connected to the relay requires 1.2A at 220 VAC.
