      The MTS-4DIO is a 4 channel digital input and output module.  It provides bidirectional digital input and output capability for an MTS series telemetry system.  There are 4 digital inputs (wet or dry) and 4 Digital outputs (form A Relay contacts). The MTS-4DIO communicates with another MTS-4DIO module. 

      Each input can be configured as a dry or wet contact input.  An adjustable ON/OFF delay can be invoked to provide hysteresis.  The input status of each channel is indicated individually.  While an input is in its ON or OFF delay mode the indicator flashes.

      Relay outputs can be configured to go into a predetermined state during communication fail events.

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