Ethernet I/O Module

Radix manufactures serial to ethernet converter, USB to serial converters, RS485 isolated repeater, etc. DCC621 is an IP based Ethernet I/O Module for monitoring and controlling applications. It can be operated over a LAN and has a variety of Input/Output functions. The module can be remotely controlled through a 10/100 M Ethernet network using the MODBUS TCP protocol. MODBUS is the de facto standard communications protocol, and is now the most commonly available means of connecting industrial electronic devices. This makes DCC621 ideal for integration with HMI, SCADA, PLC and other software systems. It has 5 opto-isolated digital input ports which can be configured as digital inputs (eg limit switches), counter inputs (eg flowmeter pulses) or frequency inputs. It also has five opto-isolated digital output ports which can be configured as digital outputs (eg to operate a relay) or PWM outputs (eg to generate a variable voltage). Digital outputs are open collector type with 100mA sinking capacity for each channel. DCC621 reads digital inputs and writes digital outputs either from a local web page or by using MODBUS TCP on SCADA software. It also has an RS485 port which is used to convert MODBUS TCP to MODBUS RTU protocol. DCC621 supports MODBUS TCP Client / Server protocol. DCC621 has a pairing function. This allows one DCC621 to be paired with another DCC621, or any other equivalent instrument of another make. After pairing, the input of the first instrument is recreated as the output of the second. DCC621 offers true IEEE 802.3af-compliant (classification, Class 1) Power Over Ethernet (PoE) functionality using a standard Category 6 Ethernet cable to receive power from a PoE switch such as the Netgear model FS108Pv3. If a PoE switch is not available, the module will also accept power input an external power supply (18 to 48 VDC). Radix also offers multihost to ethernet serial converter.

Radix also manufactures signal isolators, analog input modules, loop powered instruments, etc
