Specialty Protection Modules

Specialty protection modules provide monitoring solutions for speed, overspeed, acceleration, reverse rotation, locked rotor, thrust, case expansion, differential expansion, common process measurements and differential measurements, and temperature and differential temperature. These solutions are typically applied in the monitoring of steam and hydro turbines, aeroderivative and industrial gas turbines, turbo-expanders, large pumps, and compressors. All specialty protection modules communicate via DeviceNet™ network.

1440 Dual Speed Module

Bulletin 1440 Dual Speed Modules

The 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.

1440 Position Module

Bulletin 1440 Position Modules

The XM® 320 Position Modules are general-purpose monitors that accept inputs from a variety of measurement devices. These modules can collect trend data on events and can monitor as many as two alarms, making them complete position monitoring systems. 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.

1440 Process Module

Bulletin 1440 Process Modules

The XM® 360 Process Modules are intelligent general-purpose monitors. They are complete process monitoring systems. These modules can collect trend data on events such as relay actuation. 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.

Relay Modules

Bulletin 1440 Electronic Overspeed Detection System Relay Modules

The 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.

Temperature Modules

Bulletin 1440 Isolated Thermocouple Temperature Modules

The XM® Isolated Thermocouple Temperature Modules are intelligent 6-channel monitors. They measure grounded or isolated thermocouples. These modules provide 250V DC of channel-to-channel isolation and are specifically designed to measure temperature with thermocouple inputs.
