Signal Conditioners with In-Circuit Calibration and High Panel Density Equals Lower Costs and Easier Installation 

• RTD, T/C, mV, mA, V input transmitters, alarm trips, combination transmitter/trips and computational transmitters.
• On-board plug-in sub-module facilitates change of range or sensor type.
• Convenient front panel access to span, zero, and setpoint controls.
• In-circuit calibration and input monitoring via front panel jacks,
• without disconnecting the input or output wiring.
• Signal to power supply isolation standard on all modules.
• Input to output isolation on temperature transmitters.
• Power On indicator on all modules.
• Single and dual setpoint alarm trip and combination transmitter/alarm trips.
• Plug and socket selection for relay operation and high or low setpoint.
• Sensor failure detection without shutdown on RTD modules.
• High density mechanical design, 20 modules in a standard 19 inch (48.25 cm) rack mount.

The Ronan X51N Series process signal conditioners, transmitters, alarm trips, and combination transmitter/trips, feature the most extensive selection of interface modules, providing high density packaging for the most economical price. The designs incorporate solidly based experience from the many thousands of installed and operating units, and offer superior performance based on today's technology and proven design techniques. The high density arrangement of the X51N Series, most suitable for system application in today's space-limited control rooms, is enhanced with the ultra high density combination of transmitter and alarm trip contained in the same module. These combination modules provide a unique solution to instrumentation requirements, where previously a transmitter and an alarm trip module occupied twice the space, thus providing an obvious economical advantage.
