Relays

Time Controlled

The relay can be automatically turned on and off based on a specific time and day. For example, it can

be set to turn on automatically every weekday at 7:00AM and to turn off at 5:00PM. This is an added

benefit for the customers to utilize the instrument as a small local control system.

Remote Controlled

Individual relay can be controlled remotely via the Modbus communication. Once the relay is set to

operate on communication command, it can be turned on/off by changing the Modbus coil registers.

This allows the DCS system to control another device via the XTDL-HT™ without setting up a Remote

Terminal Unit.
