The Intelligent Transmitter pairs with the iT Alarm, a DIN-rail mountable alarm with three programmable relays for use in vibration monitoring systems or process control systems. The iT401 Alarm, which compares the 4-20 mA input from the transmitter against user-defined high or low setpoints, triggers the relays and/or provides an alert when the input deviates from acceptable levels. The front panel controls and digital LED readout make this unit very user friendly.
The real advantage of this unit is that it can also be used with any 4-20 mA sensor, including pressure, temperature, flow, speed and especially Wilcoxon’s popular LPS™ vibration sensors.

Typical Applications
Warn of trouble by providing an alarm output if a process signal exceeds a high or low limit.
Create an independent emergency shut-down system to avert undesirable situations in the event of central power failure or DCS shutdown.
Combination alarm trip and transmitter modules reduce costs when both alarming and monitoring functions are needed at the same location.
Sense dangerous conditions, and shut down equipment, before it is damaged.
Compare two variables and trip an alarm when the difference between the two exceeds a preset value.
Install multi-trip alarms to provide several levels of warning and shutdown actions.
Use for reliable, and cost-effective, on/off control of pumps and motors.
