Description: TCS temperature centralized system transmits RTD, thermocouple signals, millivolt and resistance signals from 16 or 32 points in the field to the DCS system through a pair of twisted pairs of wires, and is mainly applied in the area where the temperature points are relatively centralized and collected.

TCS temperature centralized system consists of two modules:

TCM Temperature Concentration Module: directly receives on-site temperature sensor signals and transmits them as HART signals.
HMC Protocol Conversion Module: Receives TCM HART signals and converts them into standard MODBUS signals for DCS system.
16-point temperature acquisition

32-point temperature acquisition

Centralized acquisition solution features

One transmission line instead of multiple signal lines
One communication card instead of a large number of temperature IO cards
Save safety barriers (Ex-area)
Save wiring terminals
Save wiring construction
Advantage:

Each input channel of the TCM module is independent of each other and does not interfere with each other.
Each channel can be independently and precisely set, such as input range, sensor type, etc., and each channel built-in cold end compensation can be selected.
Adopt HART and MODBUS communication protocol, open and universal.
2、Using the PC software or hand manipulator provided by Moore for remote configuration.
3、RTD, thermocouple, resistance and millivolt signals, and can be arbitrarily mixed inputs
