4. Digital output to drive a relay
When one digital output is used to a relay, it is necessary to add into the connection a protection diode
to avoid damage
to the equipment. The diode must be connected in reverse (the anode to the output
terminal of the equipment and the cathode to the positive terminal that feeds the relay).
The relay must be fed using an external power supply, sharing the GND terminal to the power supply of the
equipment, or if necessary you can use the same source which
feeds the RMS1-GR.
Output with relay (single power supply) Output with relay (double power supply)
5. The relay outputs
The relay outputs of the RMS1-GR allow us to open or close a circuit using the normal open and
common contacts of a relay.
The RMS1-GR has the particularity in relay outputs and has a common contact to each group of eight
normally open contacts. This common contact can be connected to a positive voltage as GND, taking
into account that this common contact is used for the eight terminals normally open.
