Product catalog summary

Overview: The DT1122 is a dual-output galvanic isolator designed to transmit signals from a transmitter or other signal source to two galvanically isolated outputs. This is useful for applications requiring parallel signal processing or local signal indication.

Key Features:

4-way galvanic isolation between input, outputs, and power supply.
Selectable input and output signal ranges: 0-20 mA / 4-20 mA current or 0-10 / 2-10 V voltage.
20 V / 24 mA transmitter power available for passive two-wire transmitters.
Two types of power supply options: 24 VDC ±10% (DT1122) and 230 V AC/DC ±10% (DT1122 PS).
Outstanding transmission characteristics with nonlinearity < 0.02% and temperature coefficient of 25 ppm/°C.
Front LED indicators for power and fault conditions.

Technical Specifications:

Input Parameters: DC current (0-20 mA / 4-20 mA) with 10.6 ohm resistance, DC voltage (0-10 V / 2-10 V) with 102 kohm resistance.
Output Parameters: DC current with ≤ 500 ohm load resistance, DC voltage with ≥ 500 ohm load resistance.
Transmission Characteristics: Output signal error of 0.1% FSR at 25 ºC, settling time of 250 ms (10-90%).
Galvanic Isolation: Working voltage of 250 Veff, test voltage of 4250 VDC (type test) and 2500 VDC (routine test).
Power Supply: Power consumption of ≤ 2.2 W for DT1122 and 3.3 W, 5.2 VA for DT1122 PS.
Ambient Conditions: Operating temperature range of 0-50 °C, relative humidity up to 90% non-condensing.
EMC Compliance: EN 61326-1 standard, with specific immunity and noise emission levels.

Safety and Compliance: The device complies with EN 61010-1 standards, with pollution level 2 and measurement category II. It features overcurrent protection and is designed for cabinet installation with vertical mounting.

General Information: The DT1122 is housed in a TS-35 rail mounting polyamide PA6.6 enclosure, with pluggable screw-terminal connections. It has dimensions of 12.5 × 99 × 115 mm and weighs 0.15 kg. Protection level is IP 20.

Type designation Product features Dual-output galvanic isolators / power supplies (Splitters) • signal splitting: transmission of an input signal to two independent outputs • switch-selectable signal ranges on inputs and outputs: 0-20 mA / 4-20 mA / 0-10 V / 2-10 V (in any combination) • 4-way isolation • 20 V transmitter power at the input for two wire transmitters • nonlinearity: < 0,02% TYP • temperature coefficient: 25 ppm / °C TYP • 24 VDC ±10% or 230 V AC/DC ±10% power supply • TS-35 rail mounting, 12.5 mm width 24 VDC POWER SUPPLY 230 V AC/DC POWER SUPPLY The DT1122 transmits the signal of a transmitter (or other signal source) connected to its input to two galvanically isolated outputs. This feature may be required for applications where two parallel signal processors (PLC, DCS) are operating or a local indicator of the transmitter signal is required in addition to the signal processor. Galvanic isolation is 4-way, i.e. the input, outputs and power supply are galvanically isolated of each other. The input and output signal ranges can be selected in any combination using the front switches. The signal ranges are as follows: 0-20 mA / 4-20 mA current or 0-10 / 2-10 V voltage A 20 V / 24 mA transmitter power is available at the input to power passive 4-20 mA two-wire transmitters. The device has two inputs: • current: 0-20 mA / 4-20 mA * • voltage: 0-10 V / 2-10 V * * only one input can be used at a time and two outputs: • output 1: 0-20 mA / 4-20 mA / 0-10 V / 2-10 V • output 2: 0-20 mA / 4-20 mA / 0-10 V / 2-10 V The device can be ordered with two types of power supply: • DT1122: 24 VDC ±10% • DT1122 PS: 230 V AC/DC ±10% The transmission characteristics are outstandingly good: nonlinearity < 0,02% TYP, temperature coefficient: 25 ppm / °C TYP Front LED indicators provide information on the presence of power and possible fault conditions.
