The single/dual channel voltage signals from the safety zone are isolated by safety barriers to output single/dual current or voltage signals to the danger zone, which can control instruments such as actuators (electric/gas converters) in the danger zone. It is an intelligent safety barrier product with online fault self diagnosis function. Users can also set the input signal type and output range of this product through a dedicated handheld Chinese programmer.

Explosion proof mark:
［Exia］ⅡC

Transmission accuracy:
±0.1%F.S

Number of channels:
Single/Dual Channel

The output signal of the safety barrier danger zone is:
DC current: 4-20mA
The signal type and range are determined at the time of ordering and can also be programmed by oneself

Output load capacity:
4-20mA：0~500Ω；0-10mA:0~1KΩ
0(1)-5V：≥500KΩ； 0-10V:≥1MΩ
(Please specify when placing an order if higher load capacity is required)

The safety barrier safety zone input signal:
DC voltage: 1-5V
Input impedance: ≥ 500K Ω
Note: Signal types such as 0~5V, 2~10V, 0~10V, etc. are required. Please confirm when ordering, or you can program them yourself.

power waste:
1.1W (24 power supply, single 20mA output)
1.8W (24 power supply, dual 20mA output)
Panel indicator lights:
When the instrument is working normally, the indicator light PWR is always on;
When an input signal fault alarm is triggered, the indicator light ALM (CH1, CH2 for dual channels) flashes or stays on.

Calibration:
This product adopts intelligent digital design, which can ensure long-term accuracy within the range specified in this manual. If calibration is required, please select the dedicated handheld Chinese programmer provided by our company for operation
