Isolated RS-232 & RS-485 Transceiver Modules

The SUE - SUJ series of isolated COM port transceiver modules are converters from an UART TTL-level interface to either RS-485 or RS-232 cable connection. The small modules are optionally available with Micro-D, RJ45, or D-Sub front connectors. All modules are equipped with a 2.0mm socket for either direct mounting to a suitable carrier card, or alternatively to be attached by means of a micro ribbon flat cable assembly.

With their dimensions of 59mm (length) and 20mm (width), up to four SUE - SUH modules (Micro-D, RJ45) fit into a 3U/4HP front panel. The SUI - SUJ modules are provided with a classic D-Sub connector, which requires 31mm front space. All modules were designed for highest data rates and optimum isolation and ESD characteristics. The industrial temperature range makes them suitable for rugged applications (e.g. IoT, edge computing).
