Low-cost data acquisition modules that provide direct connection to four analog signals of the same type and range to any host with an RS-232 or RS-485 port. The modules provide direct connection to a wide variety of sensors and perform all signal conditioning, scaling, linearization and conversion to engineering units. The data values are transmitted to a host computer via RS-232 or RS-485 using either the DGH ASCII protocol or Modbus RTU binary protocol. The protocol is user-selectable.
Input Types: Voltage Inputs: (+/-100mV, +/-1V, +/-5V, +/-10V, +/-100V); Current Inputs: (4-20mA); Thermocouple Inputs: (J, K, T, E); Thermistor Inputs: (2252 Ohm)
