Intrinsically Safe Relay Controller
FSIS-35P-4
SAFE STOPS & RELIABLE RESTARTS
The FSIS-35P-4 isolating switching amplifier initiates a safe, reliable response when a fault occurs, or an obstruction is detected. Equipped with complete galvanic isolation and an intrinsically safe input circuit, the FSIS-35P-4 enables safe operation of electrical equipment in explosive atmospheres. Reverse polarity protection ensures equipment is not damaged if the power supply polarity is reversed by cutting off power to the controller.
Applications
- Explosive atmospheres:
- Sensing mats
- Emergency stops
- Sensing edges
