Our Bulletin 1440 XM® 220 Dual Speed Modules accept inputs from standard tachometers. These modules operate in dual-channel, single redundant channel, or reverse rotation mode to control how sensors calculate the speed, acceleration, and peak measurements. They can operate stand-alone or on DeviceNet™ networks to provide real-time data and status information to other XM modules, programmable controllers, distributed control systems, and condition monitoring systems.
