Product Description

Product overview

It can convert the three channel switching signal in the dangerous area isolated into the digital signals, and according to MODBUS RTU protocol provide the digital signals to PHM7100, PLC or host computer systems.

PRODUCT ADVANTAGES

1.Leading technology, adopts PCB planar transformer

2.A wide range of inputs like Al, AO, DI, DO, Pl, PO, TC and RTD etc. can be provided

3.Bus power and communication (RS485 of Ethernet), flexible and convenient

4.Intrinsically safe, in the intrinsic side can be connected with intrinsic equipment in 0, 1, 2 zones, safe and reliable with excellent performance

5.High module/channel densities, save space and cost
6.Compare with traditional PLC+isolated safety barrier, avoid the failure through twice signal conversion, increase the transmission accuracy and system stability
