描述

G34205501800 is an 8-channel Dupline transmitter designed to detect the states of volt-free contacts and open collector NPN transistor outputs from devices such as inductive proximity switches. The transmitter operates with a rated input voltage of 10 to 30 VDC (ripple included = 3 V) and features optoisolated contact or NPN transistor inputs with a maximum short-circuit current of = 8 mA and contact resistance of = 100 O. It includes LED indications for supply status (green), input activation (red), and Dupline carrier presence (yellow), with a power ON delay of typically 2 seconds and operates across a temperature range of -20°C to +50°C. The device is housed in an H4 enclosure rated for DIN-rail mounting (EN 50022) with IP 20 protection and is ideal for industrial automation and fieldbus installation applications requiring reliable signal transmission over cable lengths up to 25 m.
