G34205501115 Carlo Gavazzi

G34205501115, Transmitter for Digital Signals Type G 3420 5501, G34205501115, Dupline® transmitter for exter-nal supply. Detects the states of 8 volt free contacts and signals from devices with open collector NPN transistor output, e.g. inductive proximity switch EI .... N... , G34205501115, 8-channel transmitter with 8 inputs for contacts or NPN transistors. An external power supply is not required. Each input may be coded individually by means of the code programmer GAP 1605. For details, please refer to the respective data sheet. When a contact is used to short-circuit terminals 24 and 25 (input 1), the transmitter transmits on the channel coded for input 1. When an NPN open collector transmitter between terminals 24 and 28 (input 4) pulls the input low (< +1 V), the transmitter transmits on the channel coded for input 4. Whenever the contact of the input is opened, the transmitter stops transmitting on the respective channel. Notes: - Terminals 4 and 24 are internally connected. - Terminals 4 and 24 are common (minus).
