As per the subject I wanted to know if in the range of I / O modules you also have a version with PWM static outputs such as the TRP-C28H (I saw that this only has relay outputs).
In the meantime, it is necessary to understand the range of the PWM output frequency, all these modules do not have PWM management inside them, you should manage the On and Off command on each output via Modbus. If the PWM output is used to control, for example a heating resistor of a tank, therefore quite slow On / Off times of the order of 1 ÷ 10 seconds you can use the TRP-C24H module which has 16 transistor outputs. Remember that as an alternative to these modules you can use our module for example Compact Ethernet CPU which is also available with SSR static outputs. In reality it is a PLC that with a simple program can become a remote I / O with Modbus TCP. The module costs less than the remote I / O module and is expandable with other local I / O modules to increase the number of I. The programming tool is free and you will find many programming examples (Topic, See application). Since the device is equipped with a local program, you can also manage the PWM locally by setting the operating duty cycle only from Modbus.
I have to control a dimmer with a PWM input, the problem is that I would only need one PWM and only one analog input (for temperature) and the SlimLine Ethernet seemed "wasted" to me to do this one thing.
The waste is always in the price, at today's price list for just over € 100, you buy a PLC with 6 digital inputs, 4 digital outputs and 2 analog inputs. Ethernet connectivity and all the function library available with LogicLab.
