PR Electronics 佩勒 5116B 本质安全栅

特性

• Linearized, electronic temperature measurement with RTD or TC sensor.
• Conversion of linear resistance variation to a standard analog current / voltage signal, i.e. from solenoids and butterfly valves or linear movements with attached potentiometer.
• Power supply and signal isolator for 2-wire transmitters.
• Process control with 2 potential-free relay contacts which can be configured for advanced functions.
• Galvanic separation of analog signals and measurement of floating signals.
• Within a few seconds the user can program PR5116B to suit the specific application.
• By way of the front push-button the input can be calibrated to the exact span of the process. Zero drift on the process signal can be adjusted by a single press of the front buttton.
• A green front LED indicates normal operation and malfunction. A yellow LED is ON for each active output relay.
• Continuous check of vital stored data for safety reasons.
• 3-port 3.75 kVAC galvanic isolation.
• Mounted vertically or horizontally on a DIN rail. As the devices can be mounted without any distance between neighboring units, up to 42 devices can be mounted per meter.
