Description

The Relay Contact Module is an ultra-compact DIN rail mounted unit with connections for four relay outputs and an M-BUS network. Each feed-through relay can switch 5 A with a maximum module load of 20 A.

Each of the four relays can be individually addressed and are all synchronised to zero crossing of the AC sine wave referenced to the module mains supply. This minimises the potential arc damage that can occur to the contacts.

The Relay Contact Module can be used in standalone mode where it can be set-up directly via the on-board keypad and display driven menu system without the need for a PC.

As part of a wider networked solution, Relay Contact Modules can be configured to operate as part of an EcoControls fully addressable lighting management system.
