4-20mA Current Output module (Modbus RTU)
Two varieties are available, a 1-channel and 4-channel models, providing independent 4-20mA output signals,
controlled using Modbus RTU commands. (FUTURE)
RS232 to HART (4-20mA) Output module
Provides a HART compatible 4-20mA output signal, controlled using the dataloggers RS232 port. A CRBasic library is
provided for serial communications to the interface. (FUTURE)
RS232 to UART
Converts datalogger RS232 port to TTL UART.
