MexTRACE-RMO-EXE-06
Description
Distribution and control module MexTRACE-RMO-EXE is a device used to monitor and control six heat tracing lines as part of an automated EHT control system.
The unit is capable of delivering control of heating circuits based on the data received from measuring and control module MexTRACE-RMM-EXE or its own measurement.
MexTRACE-RMO-EXE is a kit in a X-proof housing accommodating a controller and terminals.

Operation
Heating sections are controlled by switching between the following modes:
- Heater OFF – The line is always off
- Heater ON – The line is always on
- Remote – The line is controlled with higher level signals via communication interfaces
- Thermal Relay – The device supports custom object temperature relying on temperature sensor data
- PWM – The line is alternately turned on and off subject to user-defined period and PWM duty cycle duration.
- Proportional PWM – PWM duty cycle duration is interpolated linearly between two points, i.e. between the top and lower setpoints. The temperature and duration of the duty cycle are defined for each setpoint. As long as air temperature does not exceed the lower setpoint, the duty cycle value remains constant and equal to the value at the given setpoint. In case air temperature exceeds the top setpoint, the duty cycle value is equal to zero, i.e. the line is off. The time the line goes on between the top and lower limits is determined by interpolation.
