Channel Type
Transducer Type
The thermocouples or mV-level signal from the hazardous field
is picked up by this product, converted to the standard current
or voltage signal which is isolated with the hazardous area and
transmitted to the control cabinet, PLC, DCS, display etc.. The
product is equipped with cold junction compensation.
Furthermore, it is armed with RS485 digital bus interface, which
makes network configuration and the input or output configuration
possible in many application fields. It is an intelligent safety
barrier, and the type or range of the thermocouples can be set
through the host computer, moreover, cold junction compensation
does work automatically.
One independent power supply is required. Moreover, within
the product power supply, input and output are mutually isolated.
Field devices connected and regions:
J, K, T, E, S, B thermocouple, millivolt signal sensor;
Zone 0, Zone 1, Zone 2, IIA, IIB, IIC, and hazardous area of
T4~T6.

3. The length of bare wire is about 8mm, locked up by the M3 bolt.
Application about Surge Protector
Connect the ground of protected equipment or case, and ground of surge protectors directly, and connecting wire is as short as possible. Single
point grounding can make surge protectors avoid high-voltage between surge protectors and the ground, which makes protection more effectively.
Selection guidelines for intrinsically safety explosion protection system
1． The explosion protection grade of the barrier must be not less than that of intrinsically safety explosion protection device in spot.
2． Take in consideration of hazardous end output resistance and loop resistance make sure the barrier output voltage meets the minimum operation
voltage requirement of intrinsically safety device in spot.
3． The safety parameters about intrinsically safety end meets:
Uo
≤
UI, Io
≤
Iin, Po
≤
Pin
Co
≥
Cin, Lo
≥
Lin
4. Select suitable safety barrier which matches the intrinsically safety device in spot according to the power polarity, signal type and transmission
mode about the device.
5. Much more protection is required, which can avoid the influence of the leakage current generated by safety barrier on intrinsically safety device in
spot.
