RS-485 I/O Expansion Racks
-
RU-87Pn I/O expansion units are used to expand I-87K series I/O modules via the RS-485 interface. They are equipped with one power module, one RS-485 interface, one CPU module and several I/O slots. High profile I-87K series I/O modules can be plugged into the unit. RU-87Pn series I/O Expansion Racks have auto configuration. Each slot configuration can be pre-configured and stored in the CPU module. Once a module is plugged in, the CPU module will write the pre-configured data to the module. They are also hot swappable.

SparkFun USB To RS-485 Converter
-
This is the newest revision of this board and this breakout board pairs an SP3485 RS-485 transceiver with an FT232RL USB UART IC to convert a USB stream to RS-485. The SP3485 is a half-duplex transceiver, so it can only communicate one way at a time, but it can reach transmission speeds of up to 10Mbps.

PCI-104 8-Port, 4-port, And 2-port Multi-Protocol RS-232, RS-422, RS-485 Serial Communication Boards
104i-COM-8SM Family
-
The 104i-COM-8SM (PCI-104) family of multi-port, multi-protocol (RS-232, RS-422, RS-485), serial communication boards deliver up to eight high-speed serial communication ports for use in a wide variety of applications. The boards were developed for use by system integrators and manufacturers in the design of industrial and commercial systems. Based on the XR17D158, the boards have eight enhanced 16550 UARTs, each with a set of modem signals (CTS, RTS, RI, DTR, DSR, CD) in RS-232 mode.

Product
RS-422 RS-423 RS-485
-
The low-power, high-speed transceivers of this family are designed for RS-485, RS-422 and RS-423 communication applications. They usually contain one driver and one receiver in half duplex configuration. Each driver output and receiver input is protected against electrostatic discharge up to ± 15 kV and has no latch-up. These transceivers operate with a 5 V supply and draw a very low supply current when unloaded or fully loaded but with disabled drivers.

DCON RS-485 Data Acquisition
-
DCON ASCII modules communicate over RS-485 and come in many analog and digital I/O configurations including current, voltage, thermistor, thermocouple, RTD, and strain gauge. They can be daisy chained together over insulated copper wires. The I-7000 series is distributes I/O communicate over DCON ASCII Protocol over RS-485 and are available in a bevy of digital and analog configurations, much like the M-7000 series. The tM series, tiny compact modules, communicate over Modbus RTU and DCON protocols and provide Analog and Digital I/O functions like isolated digital input, relay and open-collector output.
