9116B isolator and trip amplifier

The 9116B unit is a DIN rail mount multifunction device that powers and controls all the SST Control gas, pressure and temperature transmitters.

Equipped with one status relay and one control relay plus active or passive mA output the 9116B can work from within Zone 2 or safe area locations to provide isolation, rescaling and control of hazardous area signals.

SIL 2 Full Assessment and certified in accordance with IEC
61508

Configured using a clip on mini display, signal inputs and control parameters can be set quickly and relays tested simply by button push. Password protection and cable break indication can also be set.
