NP900 Series:  CEE's latest relay products.  These are multi-function devices with programmable HMIs, 3-level password protection and advanced communication options including IEC61850, Modbus TCP and Modbus RTU protocols.  Some products are available with built-in arc detection. 


NP800 Series:  Microprocessor-based multi-function relays.  Some models are designed as retro-fits to systems with older single-function relays using CEE's plug-in base design "R-Case".  Available with Modbus communication options.


PROCOM Series:  CEE's original microprocessor products for more specialist applications.  Robust and reliable products with J-Bus 0-20mA communications (selected models available with Modbus)



7000 Series:  Static single-function relays without microprocessors.  Highly reliable with a long service life, selected models are available with class E1 certification for Nuclear applications.  These products also serve as useful replacements for obsolete GEC MIDOS relays.


Auxiliary Relays:  Relays for logic and back-up functions not directly related to power system protection.  Includes timers, latches and lock-out relays. 



Railway Relays:  Specialist relays for railway, tramway and traction applications which don't fit our standard product categories.  Includes protective devices for catenaries and traction transformers. 



Generator and Motor Control Products:  Control devices from our sister organisation Technirel.
