HD5542 Zhejiang Supcon Safety Barrier

The HD5542 analog input intelligent isolated safety barrier provides a set of isolated power supply for intrinsically safe 2/3-wire transmitters on-site, isolates and replicates the (4~20)mA current signal from the field to the output end, and offers line fault alarm indication. For smart transmitters, the HD5542 supports bidirectional HART protocol communication.

Number of Channels 1 Field Device Explosion-proof Rating After proper certification, the field device can be used in hazardous areas of Zone 0, II C, T4-T6 Power Supply Voltage: (20~35)VDC Current: 51mA (at 24V power supply, transmitting 20mA) Signal Transmission Range (4~20)mA *Note: Supports a maximum signal range of (0~24)mA. Signal Output Characteristics Load Capacity: (0~360)Ω (at 24mA output) (0~450)Ω (at 20mA output) Output Impedance: Greater than 1MΩ Response Time 750μs (with a typical 250Ω load) Power Distribution Output (Hazardous Side Power Distribution Port) When transmitting 20mA, the distribution voltage is greater than 15VDC Fieldbus Protocol Supports bidirectional HART protocol communication
