Conlab has released a new 8 channel 4-20mA to MODBUS wireless interface unit. The unit will interface to 8 galvanic isolated 4-20mA signals sources or any mix of other sensors.
A built in wireless interface module enables remote monitoring of these inputs, when using MODBUS protocol. In addition, there are two digital input/output signals that can be used for remote ON/OFF commands.
The wireless section can utilise one of three different radios: ZigBee 2.4GHZ short range, 922MHZ medium range and 922MHz long range.
