Trip amplifiers suit for SIL 1 applications

Edited by the Engineeringtalk editorial team May 25, 2005

Omniflex reckons the Omniterm Dual Trip Amplifier has to be considered for any application where hardwired trips are required.

Omniflex reckons its Dual Trip Amplifier is all you need for safety critical applications where set points being reached by 4-20mA, 0-10V (1-5V), universal input thermocouple, millivolt, RTD, volt or frequency signals are to be alarmed to either alarm annunciators, PLCs or DCS systems.

These high accuracy dual trip amplifiers are equipped with two settable limit alarms/trips with an optional retransmit, and are user configurable in minutes.

This allows the user to keep only one type on the shelf, minimising stock holding and reducing inventory costs.

No field calibration is required on these units, which also means low installation and commissioning costs.

The trip amplifiers have been designed to meet the criteria for SIL 1 applications with high reliability in mind.

For example, a built-in wire break detection circuit that will de-energise the trip relays is a standard feature.

With high accuracy, reliability and a significant cost saving over its competitors, Omniflex reckons the Omniterm Dual Trip Amplifier is a real winner and has to be considered for any application where hardwired trips are required.
