You should consider D series Modbus RS485 current input modules. Because they let you read current output sensing devices with spare Modbus RS485 ports for temperature measurement.
Modbus RS485 current input
The D series is a versatile family of Modbus RS485 input modules, because a signal range is available for many sensor measurement applications, the supply voltage range is a wide 10 to 30Vdc (DIN rail unit 5Vdc), as well as Modbus compatibility with a number of software options
When you have spare a spare RS485 port, and need to add current measurement, use D series current input modules. Because D series current input modules allow the simple measurement of industry standard signals. They use the standard Modbus protocol. So you can easily connect your existing current output sensing devices to modern control systems. They are a simpler way to add current measurement to a RS485 bus than other types. Current output sensing devices are commonly available sensor signal conditioners. Because they are common, they are in many cases used in HVAC systems, refrigeration systems, chillers, environmental monitoring, computer room monitoring, dryer, and a variety of other applications.
When you need simple to use Modbus RS485 current input module, use the D series. In other words D series Modbus RS485 current input modules are a simple way to add current measurement to a RS485 bus.
