Product Description

Ethernet to Serial Device with 2 Port software selectable as RS232, RS422/485 Full duplex or RS422 Half duplex. ES-522 has removable Screw Terminals Blocks for easy wiring, a slim ‘end on’ case and integral DIN rail mount. Our Industrial Ethernet to Serial has an operating temperature range of -30 to +80 degrees Celsius and with +5VDC to +30VDC Dual input reverse polarity protected power supply making it perfect for industrial applications. Data transfer rates up to 1,000,000 baud (1 MegaBaud), coupled with 1Mbit/s line drivers deliver uncompromising performance. Baud rates can be standard values such as 9,600, 115,200, 230,000, 921,600 or user definable non standard values.

Our Industrial ES range provides simple instant networked serial ports in demanding environments. Serial Port Tunnelling (peer to peer) allows serial cable replacement over any distance, no software required. Suitable to be wired into existing power and network infrastructure or can be used with our PW-600 power supply.
