Houston, TX – SIS-TECH announces the latest revision of the Diamond-SIS- an alarm/trip module used for safety alarms, equipment protection interlocks, and safety instrumented systems in the process industry. The same input signal used to trigger the safe state of the Diamond-SIS output (rated for 5 amps total load) is easily transmitted back to the process control system through the isolated 4-20mA output now included in the same hand-sized footprint as the original release. No 3rd party equipment is needed to send the input signal to other systems. The Class 1 Div 2 rating of the din-rail mountable Diamond-SIS supports installation near tanks, boilers, heaters, furnaces, pumps, and other applications where the operator needs to interact with the process equipment locally, while being monitored for safe operation.
