Considering the installation of a point io system, featuring a 1734-AENTR communications adapter along with ten 1734-IT2L modules. In the installation, a 1734-EP24DC module is added after every set of three IT2L modules. It may seem unnecessary to incorporate multiple EP24DC modules in this configuration. The 1734-IT2I module consumes 175mA, while the 1734-AENTR is capable of providing up to 1A of power (with a recommended maximum of 750mA) and the 1734-EP24DC can supply a maximum of 1.3A (with a recommended maximum of 1.0A).
I have encountered the limitation of only being able to use three 1734-IT2I modules per power supply. Additional modules can be added, but adding a fourth one often causes issues. While I have not found an explanation, it is clear that Rockwell is aware of this restriction as they do not allow configuration of more than three modules.
From a power perspective, incorporating multiple 1734-EP24DC modules actually makes sense in your configuration. Each 1734-IT2L module has a consumption of 175mA, so three would collectively consume 525mA power. If we take the 1734-AENTR's recommended maximum current of 750mA, after factoring in the three IT2L modules, you are left with just 225mA - which is borderline for buffering and system stability. Therefore, adding 1734-EP24DC after every set of three IT2L modules, with its ability to supply up to 1A power, gives you a more robust design and caters for any unexpected spikes in power consumption. Power considerations are crucial in any automation system design and it's better to safely exceed the needs than fall short.
Incorporating multiple 1734-EP24DC modules might seem like overkill at first glance, but it's actually a smart move. Given that each 1734-IT2I module consumes 175mA, having three underway quickly stacks up to 525mA. Add the consumption of the 1734-AENTR adapter into the mix, you'd easily be pushing the recommended upper limit. Inserting a 1734-EP24DC after every trio helps to distribute the power supply effectively, preventing any single module from getting overloaded. It provides a kind of reinforcing layer to your power distribution and ensures smoother operation. Think of it as a safety net for sustainable power management.
While it might seem overkill to include several 1734-EP24DC modules in your setup, it's actually a smart idea when you think about the power consumption of your other modules. The 1734-AENTR and 1734-IT2I modules alone are quite power-hungry, with the AENTR pulling its recommended max at approximately 750mA at times. That doesn't leave much room for the ten 1734-IT2I modules, each running at 175mA each. Adding a 1734-EP24DC module after every set of three 1734-IT2I provides you with an power buffering mechanism that can ensure safety and increase the stability of your system. It basically acts as a "power insurance".
While it may seem unnecessary to include multiple 1734-EP24DC modules at first glance, it's important to consider the fact that these modules are designed to mitigate power distribution issues within your point io system. Given that both your 1734-IT2I modules and 1734-AENTR adapter consume significant amounts of power, evenly distributing the power load across the system becomes crucial to ensure optimal operation and preventing any overload conditions. The 1734-EP24DC module serves the necessary purpose of providing that additional power, hence ensuring the longevity and reliability of the entire system.
