Potentionmeter input safety barrier

Potentionmeter input safety barrier

The potentiometer is input to the safety barrier, and the 2-wire / 3-wire potentiometer signals in the danger zone are converted into current signals and output to the safety zone. This product requires independent power supply, and the three terminals of input, output and power are isolated. With online fault self-diagnosis function.
HD-5071Communication input safety

HD-5071Communication input safety

The RS485 digital communication signal from the danger zone is isolated and output to the safety zone, and the intrinsically safe power is provided to the instrument in the danger zone. Serial communication can be networked through a dedicated communication interface. This product requires independent power supply, and the three terminals of input, output and power are isolated.
Millivolt input ,millivolt output isolated safety barrier

Millivolt input ,millivolt output isolated safety barrier

The thermocouple / millivolt signal from the dangerous area is output 1: 1 to the safe area after isolation, and it can also output analog signals at the same time; it can be used with various types of thermocouples and weighing transmitters.
Analog output safety barraier

Analog output safety barraier

Analog output safety barrier, input 4 ~ 20mA current signal from safe area, output 4 ~ 20mA current signal to danger area through isolation, drive valve positioner and other equipment on site, and support HART signal bidirectional transmission. This product requires independent power supply, input, output and power are isolated at three terminals.
Resistance input, resistance output isolation safety barrier

Resistance input, resistance output isolation safety barrier

Output the resistance signal from the dangerous area to the safe area through isolation 1: 1. It can output two resistance signals at the same time, and it can also output one resistance and one analog signal at the same time.
HD-5011 Single channel digital input safety

HD-5011 Single channel digital input safety

Digital input, relay output safety barrier, dry contact in the isolation zone or NAMUR-type proximity switch signal, relay contact to the safety zone through isolation output You can independently set the output and input in-phase or reverse-phase logic control through the DIP switch (default in-phase), and set to enable or disable line fault detection (by default, the line fault is the LED flashing). This product requires independent power supply, and the three terminals of input, output and power are isolated.
