ADAM-4017+ 8-channel Differential Analog Input Module
Here comes a solution to the demand for more channels of analog input.
Similar to its counterpart, the ADAM-4017+ enables eight differential
channels with multiple input ranges. This multi-ch/multi-range structure
allows channels with different input ranges at the same time, say channel 1
with the range +/- 5 V meanwhile the others with +/- 10 V and +/- 20 mA.
Instead of leaving two single-ended channels in ADAM-4017 module due
to the limit number of pins, the ADAM-4017+ uses a jumper to switch
AGND and INIT* to Vin6- and Vin7-, respectively, to allow 8-channel input.
Additionally, the ADAM-4017+ has been expanded to accept 4 ~ 20 mA so
the user can employ it in various applications
ADAM-4018+ 8-ch. Thermocouple Input Module
Here comes a solution to the demand for more channels of thermocouple
input. Similar to its counterpart, the ADAM-4018+ enables eight differential
channels with multiple input types. This multi-ch/multi-type structure
allows channels with different input types at the same time, say channel 1
with K input type meanwhile the others with R and S types.
ADAM-4018+ is an 8-channel T/C input module. Compared with the
universal analog input module ADAM-4019, it is rather dedicated to T/C
and 4 ~ 20 mA inputs for those with special request. It improves ADAM-
4018, the traditional design six differential and two single-ended channels,
to enhance the steadiness and reliability of wiring. Usually, broken external
will lead to inaccurate current value. ADAM-4018+ provides burned-out
detection so that users can easily troubleshoot broken wiring problems.
