Wago 750-651 WAGO I/O-SYSTEM 750 Communication Module
Serial TTY-Interface, Type of signal: TTY 20 mA, Baud rate: 1,2-19,2 kBd, Parity: None, No. of Data Bits: 8, No. of Stop Bits: 1, Bit transfer: 2x 20 mA, Transmission channels: 1-TxD/1-RxD, full duplex, Bit width: 1x 24 Bit input/output (3 Byte User Data) 1x 8 Bit control/status, Buffer: 128-Byte Input/16-Byte Out
The interface integrated into the I/O module allows the connection of any device which is equipped with a 20mA current interface (TTY).
This interface is passive both at the sending and at the receiving end.
It can be connected with active, semi-active or passive (with external power source) subscribers.
The module communicates with the control unit via the fieldbus coupler.
The active communication channel works independently of the higher-level fieldbus system and allows full duplex operation up to 19200 baud.
The TTY interface guarantees high interference immunity because of the electrical isolation and the driven loop current.
Internal bit width:
1x 24-bit input/output (3-byte user data)
1x 8-bit control/status
