WAGO 750-651 I/O System 750 TTY Serial Interface Module

Product overview

The WAGO 750-651 is a TTY serial interface module of the WAGO I/O System 750 for devices with a 20 mA current loop interface, wired through TxD, /TxD, RxD and /RxD. It works in active, semi-active or passive operation with 1 TxD / 1 RxD in full duplex at 1200 … 19200 baud, with MARK at I ≥ 12 mA and SPACE at I ≤ 2 mA, a load impedance below 500 Ω and line lengths up to 800 m depending on baud rate. It has a 128 bytes in / 16 bytes out buffer and exchanges 1 x 40 bits data with 1 x 8 bits control/status. The module draws 55 mA internally, has 500 V system/supply isolation and has no power jumper contacts. It measures 12 x 64 x 100 mm (W x H x L, height from the upper edge of the DIN rail) and weighs about 55 g.
