PRODUCT CLASSIFICATION
Safety Barrier
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-PI is a combination of output-type intrinsically safe isolator and input-type intrinsically safe isolator.
TCA-AT intrinsically safe thermocouple converter is a temperature transmitter which converts field thermocouple millivolt resistance into standard current.
TCA-DI applies to OC, level, contact switch or NAMUR proximity switch input.
TCA-DO is used to control the power supply in safe areas by means of the switch or logic level signal and drive intrinsically safe equipment on site in hazardous areas such as the electromagnetic valve and alarm.
TCA-PI applies to supplying isolated DC to transmitters in hazardous area and accepting current signal input from the transmitter.
TCA-RS485 is used to convert the RS485 signal or RS232 signal or USB communication signal in safe areas into RS485 digital signal by means of isolation, and then transmit the signal to field instruments in hazardous areas.
TCA-RTD intrinsically safe Thermal resistance converter is a temperature transmitter which converts field thermal resistance value into standard current.
TCA-TP is an intrinsically safe instrument for signal transmission, connecting various sensors and actuators in dangerous areas. After isolation, it transmits and outputs the standard current signals to control systems or other instruments in safe areas.
For TCA-TP11BJ, one set of relay contacts are added on the basis of universal signal input intrinsically safe isolator for the alarm output of power distribution, current, thermal resistance, thermocouple, millivolt signal, sliding resistance, etc.
TCA-TPTESU Intrinsically safe 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.
TCA-ZT applies to thermal resistance or thermocouple signal input in hazardous areas.
