FMX550

This RCR module is to be built into the poly phase electricity meter ZE310. with a standard opto interface. It has a separate panel that can be easily inserted into the meter compartment and is covered with the meter box. K2 and K3 relay contacts (with switching current of up to 8 A) are led to terminals that are accessible only after removing the terminal box cover. K1 and K4 relays used for switching the meter rates are optron based in the FMX552 type.

Both the contact programming connector and selftest button are accessible only after removing the meter cover. The module is completely (except for the power supply) galvanically separated from the meter.

Function:

• Optical interface
• 1 up to 2 relays
• Back-up time
• Programmatically optional program code
• Switching current 8 A
