BAMO CST supply power isolator relay is convenient to use when no 24 V DC main supply available on site. It supplies power 15 V DC to a Maximat sensor and it is as well contact protection of the optocoupler output of any Maximat sensor.
Whereas BAMO coupling relay KRC is contact protection of the optocoupler output of any Maximat sensor when there is an existing main power supply of 24 V DC.
