Shelly 1PM Gen4: eher Smart-Relais mit Strommessung als Haus-Energiemeter

Der Shelly 1PM Gen4 ist vor allem dann interessant, wenn du einen einzelnen Verbraucher schalten und gleichzeitig den Stromverbrauch sehen willst. Das kann zum Beispiel bei Licht, Heizung oder einzelnen Geräten sinnvoll sein.

Wichtig ist aber die Einordnung: Das ist keine Lösung für die komplette Haus-Energieüberwachung, keine klassische Mehrkreis-Messung und auch nicht die passende Kategorie, wenn du Wallbox, Wärmepumpe oder mehrere Stromkreise getrennt überwachen willst.

PL-100 mini programmable logic controller by GIC India is a real-time system designed for multiple inputs and output arrangements. The PL-100 monitors' inputs and changes outputs as controlled by the user program, including Boolean logic, counting, timing, complex mathematical operations, and communication with other intelligent devices. 

Features:

Supports up to 112 IOs

Relay Base & MOSFET Low Side Base modules

Stacking using FRC cable up to maximum 6 Expansion Modules

Isolated Digital Inputs with sourcing & sinking capability

Isolated Digital Transistorized Outputs (Low Side and High side driver)

High-Speed Inputs – Single / Quadrature (1x/2x/4x)

High-Speed Outputs (PTO / PWM / S-Profile)

Analog Voltage/Current Inputs and Outputs of 0-10 V / 4-20 mA

PC Software for programming, online & offline simulation

Standard RS232/RS485 port with RJ11 for HMI/SCADA Interface

Mini PLC has Modbus RTU support

128 Weekly, Monthly & Yearly Time Switches each

All but the simplest of powered equipment needs to be controlled in some way. Even brightness, which can be managed adequately with a single switch, can benefit from additional controls, as then the intensity can be made to stay on for defined periods, switch on and off at planned times, or switch on when one or more sensors are triggered. Traditionally such a control system would have been constructed using relays and timers, but 'smart relays' are a simple, low-cost alternative that offers an additional advantage in that they can be reprogrammed to modify the existing functions or to enable the smart relay to be reused on an entirely different application.

Smart relays have further in common with programmable logic controllers (PLCs) than conventional relays. Yet, the term 'smart relay' is used to differentiate them and emphasize the lower price compared with even the smallest of traditional PLCs. People are processed either appropriating pushbuttons and a small screen on the front panel or via a computer. Smart relays were first started over a decade ago; very soon, there were numerous different models available from suppliers of automation products, and it quickly became apparent that some were rebranded versions of others.

There are lots of ‘Smart Relay’ solutions possible today and to be honest, it is hard to choose one from another because they are all very similar and offer the same features.
