The MTS-4AI is a 4 channel analog input module. It provides analog input capability for an MTS series telemetry system. The MTS-4AI communicates with its counterpart, the MTS-4AO analog output module. Inputs can be wired to be sinking or sourcing depending on the 4-20mA signal source. 24VDC is also available on the input terminals for 3- and 4-wire connections. Input resolution is 16-bits for high accuracy.

Deployment and installation is as simple as plugging the needed I/O modules into the communications module and assigning unique module IDís. Power and communication for the modules are provided through an integral bus.



  • Inputs: 4-20mA sinking, 4-20mA sourcing, 3- & 4-wire
  • Input Impedance: 200 ohms
  • Power Consumption: 2VA (sinking inputs)
  • Reverse Polarity Protection: Yes
