Relay Modules

Our Bulletin 1440 XM® 440, 441, and 442 Relay Modules are components of the Electronic Overspeed Detection System (EODS). Three relays act as redundant shutdown relays, and a fourth relay provides alarm annunciation. Overspeed alarm inputs come from three independently connected XM-220 Dual Speed Modules, and the module requires no configuration.
