RS-422 serial interfaces

Four potential-separated channels with fast and flexible communication

The slide-in module provides four 9-pin serial interfaces.

The devices connected to a serial interface can communicate with the automation unit in various ways:

• Standard driver for "known" laboratory devices
• NAMUR driver for "unknown" laboratory devices

The channels are potential isolated (insulation voltage 35 V) and assigned according to the DTE configuration.

Features & benefits

• Independent SIO channels with FIFO storage, supports RTS/CTS hardware handshake
• Parallel processing of all channels, thus reducing time loss
• Max. transfer rate 38,400 baud (per channel)
