PEPPERL FUCHS LB7004A-254846 Universal InputOutput
Introduction
- 4-channel
- Analog input, digital input, analog output, digital output
- Installation in Zone 2 or safe area
- Supply circuit 21.5 V (4 mA)
- HART communication via field bus or service bus
- Simulation mode for service operations (forcing)
- Line fault detection (LFD): one LED per channel
- Permanently self-monitoring
- Module can be exchanged under voltage
Function
The device is a configurable universal module. Each channel can operate in the following modes:
- As an analog input (AI) it feeds 2-wire transmitters.
- As an analog output (AO) it can drive proportional valves, I/P converters, or local indicators.
- As a digital input (DI) it reads dry contacts.
- As a digital output (DO) it can drive solenoids, sounders, or LED.
A combination of analog and digital I/O is possible.
Channel LEDs indicate the status of each channel. White LEDs indicate whether AI, AO, DI, DO are selected.
The signals are galvanically isolated from the bus and the power supply.
