■ Overview

 TC-TPTESU special I/O universal signal isolator is a general instrument used for various special

input and output signals, external power supply and other special output forms. The application

scope of output signals is wide. The output current zero extends to value 0. Output voltage zero

extends to negative value.

 Switches signal inputs such as power distribution, current, thermocouple, thermal resistance,

millivolt and sliding resistance according to different wiring modes. Setting of the configuration for

input signal types or range can be made under during the power-off state. 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 22 mA. 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 DA converter has 14-digits. The current output load range is 0-550 Ω, and the output

current high limit is 25mA. Load change error < ±2 μA/550 Ω. Output voltage internal resistance <

250 Ω.

 Range of the output current: 0~20 mA, null point and range within this scope can be shifted as

required.

 Range of the output voltage: -10~+10 VDC, null point and range within this scope can be shifted

as required.

 During current output application, an external power supply can be used for the output circuit.

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

 The instrument panel of TC-TPTESU special I/O universal signal isolator includes 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. There is no power light on the intrinsically safe isolator panel. The power supply indicator is

replaced by the basic model printed on the panel. After the power is on, the model on the panel

becomes illuminated by means of 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.
