Product Details

■ Overview

 TC-TP is used to input the current, thermal resistance, thermocouple, millivolt, sliding

resistance and other signals; provide the power distribution for the field transmitter and

receive the current signal input from the transmitter. Following isolation, it converts it into

the standard current signal and then transmits it to the control systems or other instruments.

 The universal signal isolator switches signal inputs such as power distribution, current,

thermocouple, thermal resistance, millivolt and sliding resistance in various wiring modes.

Input signals can complete the configuration settings by means of the calibration software

and interfaces (accessories optional). Configuration parameters only include three items, i.e.

signals (or graduation), null point and full scale, which can be conducted in the state of no

power. The accuracy after normal use is greater than 0.03%FS. Input is open circuit or short

circuit, the output is above the high limit or below the low limit, the default value of the

configuration is output greater than 22mA. The configuration can also be reset.

 Thermal resistance input range: 10 Ω~400 Ω; minimum resolution: ±2 mΩ; stability: ±3 mΩ.

When the compensating lead error of three-wire input is not less than 50 ℃ range (Pt100),

the additive error is not more than ±0.02 ℃.

 Thermocouple input voltage range: 4~80 mV; minimum resolution: ±1 μV; stability:

±2 μV. The additive error of cold junction compensation is not more than ±1 ℃.

 The maximum range of the sliding resistance is 0~500Ω. When the range is less than 50Ω,

the three-wire form should be used for connections. Input mode offsets the lead error.

Accuracy ±0.05% FS

 The maximum range of DC millivolt should be 0~100mVDC, and the minimum should be

0~5mVDC, with the accuracy of ±0.05%FS. Minimum resolution: 1μV; stability: 2μV;

temperature drift: ±20PPM/℃.

 The power distribution voltage is more than 16VDC. The power distribution output clamp

current can be customized as required, but must be specified upon ordering. The factory

default is 28 mA (±2 mA).

 For power distribution or current input/output, the typical accuracy value is ±0.05% FS;

and the temperature drift is ±0.1 μA/℃.

 The output signal can be extended from 4~20 mA to 0~20 mA.

 The output self-adaptive load is 0~800 Ω (Note: 1-input & 3-output load is 0~550 Ω, and

1-input & 4-output load is 0~350 Ω).

 The power supply range can be chosen from within range of 20~42VDC or 15~42VDC.

 See the “Technical Data Sheet” in the specifications for current consumption or other

functional indices.

 The instrument panels for universal signal isolators include two types: LCD and LED

backlight. The LCD can display the input value, output value, or the position number

required by the user. In case of no LCD, the LED backlight design shall be used for the

instrument panel. After the power is on, the model on the panel becomes illuminated by

means of the LED backlight.

 Clamping type structure, a 35 mm DIN standard guide rail clamping type installation is

used. Screw terminal, the wire is connected and fastened by M3 screws.
