Our IO modules are designed for every application in the fields of building automation, industrial automation and infrastructure. With a size of 4/8 or 12MU depending on the total amount of build-in IOs, these IO modules fit in every switchboard cabinet. We offer only IO modules suitable for the 45mm cutout of a standard electric switchboard cabinet.
Basically we deliver two versions of every IO module: One with build-in RS485 interface with MODBUS/RTU Slave protocol and one with Ethernet interface and MODBUS/TCP protocol. All IO modules support also simple ASCII protocol to use the IOs with a media control system or with a IoT controller using Node-RED, NodeJs or Phython. The versions with Ethernet support in addition to MODBUS/TCP Server protocol also MODBUS/RTU protocol via Ethernet. All of our modules have a wide range power supply of 12-48Vdc.
HOW TO CONFIGURE?
Use our free software RESIConfigurator to parameterize and test our IO modules. We deliver for every product a complete ASCII command list and a MODBUS register table with extensive explanation.
In this product group
you will find all of our IO modules with analog inputs and/or analog outputs. Our flagship analog IO modules offer universal analog inputs or outputs. You can select a different analog IO function for every channel: Analog input (0/2-10V or 0/4-20mA) or analog output (0/2-10V or 0/4-20mA), resistor input (0-1MOhm), PT100, PT1000 or NI1000-DIN43760 temperature sensor input or digital input for dry contact or 24Vdc. But we offer also traditional analog input or output modules for -10V to +10V signals. Last but not least we produce IO modules for temperature sensors: Read the actual temperature from up to 8 RTD sensors. Cabling of the temperature sensors can be 2-wire, 3-wire or 4-wire. Sensor types can be PT100, PT1000 and NI100-DIN43760.
