MaxWell programmable temperature controller (MTC-48)

1 ) MaxWell programmable temperature controller (MTC Series) detailed Features:

Input Signals:

TC:K,S,E,J,T,B,N,R
RTD:Pt100
Analog signal:0-5V,1-5V,0-10V,2-10V,0-20mV,0-50mV,4-20mA, 0-10mA,0-20mA

Display:
Dual line four digits LED display, bar graphic display. Celcius and Fahrenheit switchable

Measuring accuracy and resolution:
0.2%F.S accuracy, maximum 0.1 resolution for TC and RTD input, 0.001 resolution for analog signal
such as 4-20mA.

Main output:
Relay contact output, SSR Drive output, 4-20mA output, 0-20mA output, 0-5Vdc output
0-10Vdc output, 1-5Vdc output

Control action:
Heating or cooling control configurable, PID algorithm. when P=0, ON/OFF control

Alarm and alarm mode:
Maximum 3 alarms,15 different alarm modes, refer to user manual for detailed alarm modes

Auto/manual control switch:
Auto/manual bumpless switch between each other, available for all sizes except size 48mm*48mm

PV/SV Re-transmission function:
The process value or setting value can be re-transmitted as analog signal such as 4-20mA

Decimal pp:
The process value or setting value can be re-transmitted as analog signal such as 4-20mA

Programming:
Maximum 4 programs can be programmed, each program with maximum 8 segments, all different
program can be linked as one program with maximum 32 segments

Output restriction:
The maximum output can be restrained in certain range, for example 80%, maximum output can be
defined at specific segments

System timing:
The system timing unit can be seconds, hours, or minutes and field configurable

Program monitoring:
Be able to check current running segments and program running time. RS-485 optional for remote
monitoring and configuration

Program control:
>Program can be executed from “0" or from the process value
>Program can be executed automatically right after power on
>Program can be executed or terminated from front panel
>Program can be restored after power failure situation.
>Program can be configured to repeat itself after finish a program
>Program can be configured to STOP itself after finish a program

Holdback function:
Holdback indicates that the process value is lagging the set point by more than a preset amount and
that the program is in HOLD, waiting for the process to catch up.

Master/Slave communication mode:
Number of controllers can be connected to a master controller as slave controller, any setting you
made to the master controller will be reflected to the slave controller, This will save a lot of time if more
controllers are doing the same job at the same time with same settings.
