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.

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.
Use of an Interposing Relay for Increased Contactor
One viable solution is to use an interposing relay. This allows room for the embedded bidirectional diode assembly to do its job. The interposing relay''s Normally Open (N.O.) will easily accommodate the higher voltage. At
6 FAQs about [Comoros interposing relay cabinet]
What is an interposing Relay Cabinet?
An interposing relay cabinet is a device used along with automation devices to control heavy load circuits like AC and refrigerators. It has auto/manual switches to bypass the loads from automation controls and provides feedback of switch positions to the control panels.
What is an interposing relay?
Interposing relays can ‘change’ a control (coil) voltage circuit into a higher or lower load voltage. Interposing relays can use a small control (coil) current and translate it into a substantially higher load current that would damage the sensitive digital controls.
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.
Which type of interposing relay is needed for a PLC?
The PLC relay is DC type with an output voltage of 24 V. But we need a DC type interposing relay with a coil voltage of 24V DC but the contact AC type with 230 V. The PLC operates interposing relay in the first stage & Contactor through its Auxiliary contacts.
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.
Do interposing relays need to be rated?
The coil of the interposing relay should require less voltage and current than the driving relay is rated for, and the contacts of the interposing relay must be rated to handle the requirements of the load ( Controller).
