I would like to know if the DT80 can send a controlling voltage that is proportional to what is being read on an analog channel.

Good morning gsc,

Sorry but the DT80 doesn't have an analog or PWM output.

Cheers,
Roger

Hi gsc,

You can use an ASCII or even MODBUS to analogue converter. The device would connect to the Serial Sensor Channel or the Host Communication port on the DT80 or DT85.

Try Amalgamated Instruments in Sydney Australia. http://www.aicpl.com.au/

I think the unit listed below might be the correct one, but please confirm this with Amalgamated Instruments.

Model: RM4-485-DC-5E-A DIN rail RS422 process module
Input: RS485 serial data
Supply: DC (wide range 12 to 48VDC nom)
Display: 5 digit 7.6mm LED plus front panel programming keypads
Output: 2 x setpoint relays (standard)
Option: Analogue 4-20mA (or DC volts) 12 bit isolated retransmission

Good afternoon Michael,

Have you used these? There are several devices on the AIC web site that look very useful and if you have found they work well you could add them to the 3rd party products list in the FAQ.

Cheers,

Hi everyone,

We have released series 4 logger in 2017 which has one analog output. Users may set the output either as voltage (0-10000 mV) or current (0-20 mA) and also this output can be linked with the measurement directly or indirectly through scaling.
