Описание товара: 542175 Pepperl Fuchs Digital Output with Shutdown Input / 1 digital output, 2 digital inputs / Inputs and output Ex ia
Features • 1 digital output, 2 digital inputs • Inputs and output Ex ia • Installation in suitable enclosures in Zone 1 or Zone 21 • Positive or negative logic selectable • Simulation mode for service operations (forcing) • Line fault detection (LFD) • Permanently self-monitoring • Output with watchdog • Output with bus-independent safety input • Up to SIL2 acc. to IEC 61508 • Module can be exchanged under voltage (hot swap) Function The digital output features 1 output with 2 feedback inputs. The device can be used to switch solenoids, sounders, or indicators (without line fault detection) in the field. Furthermore, the device accepts digital input signals of NAMUR sensors or mechanical contacts from the field. The output can be switched off via a contact. This can be used for bus-independent safety applications. Open and short-circuit line faults are detected. The intrinsically safe inputs and the output are galvanically isolated from the bus and the power supply.
