| Our intelligent site- and PC- programmable alarm features an integral digital display; fast setup using either on-board controls or a PC; two or four relays; and an auxiliary analog output. |
|
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.
