REL.44: Modbus slave relais
The REL.44 module has 2 bistable, potential-free 16A relay contacts and 2 low-power solid-state outputs for switching connected consumers.
In addition, there is also a P1 connection for reading the digital meter* and 2 pulse inputs for counting and/or time measurement of consumers via pulses.
This module can be connected to a MEMo3 wired via Modbus and configured and controlled from there. Multiple REL.44 can be connected to the MEMo3 web server.
The REL.44 is a 'Modbus slave' i/o module and can therefore also be used to interface with any Modbus master, as a Modbus relay, but also as a P1 to Modbus and or pulse to Modbus interface. The list of Modbus registers can be found below.
- Activate the Belgian digital meters in advance to be able to work: via this link
If the digital meter display shows a triangle above “GP” (GP is laser marked below the display), then ports P1 and S1 are active.
- Some (slightly older) digital meters supply insufficient or no current to supply ReMI (about 200mA), in which case you have to provide a 15 VDC power supply yourself.
- If no digital meter is available, you can connect Modbus meters yourself to register the (total) consumption, and then an external power supply is also required.
