TCA-AO applies to connection between output signals of the control system and the field intrinsically safe circuit. After being isolated, it transmits 4-20 mA analog signals to the field actuator.
TCA-AO applies to connection between output signals of the control system and the field intrinsically safe circuit. After being isolated, it transmits 4-20 mA analog
signals to the field actuator. It can also transmit HART communication signals in a superimposing manner while transmitting the analog signals (optional).
Accuracy ±0.05% FS Temperature drift (typical value) <±1μA/10 ℃.-20 ~ +80 ℃ temperature test, typical value < ±10 μA.
The test preheating time is 0.
Output signals can be extended to 0~20 mA.
Output self-adaptive load: 0~800 Ω. High limit of the output current is 25 mA. Load change error < ±2 μA/800 Ω; impact of load open circuit on the other output < ±2 μA.
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.
There is no power light on the instrument panel. The power supply indicator is replaced by a model printed on 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.
