0-20ma Analogue Fiber Mux

Adam module Industrial rail 1-4 channel 4-20mA analog optical transceiver

Overview
This series of devices adopt large-scale FPGA design and original technology and can support 1-4 channel analog signal (current/voltage) to optical fiber relay at the same time. The device is powered by 12-55V AC or DC power supply high performance FPGA programmable devices no MCU processing high-speed conversion sampling frequency can reach 20KHZ 12-bit AD conversion chip which solves the problems of electromagnetic interference ground loop interference and lightning damage greatly improving the problem. Control signal reliability security and confidentiality and also solve the problem of limited cable transmission distance.
Features
◆ The device is paired the local signal input and the opposite signal output; 
◆ Support 4~20mA 1-4 way current; or support 0~10V/0~5V 1-4 way voltage; 4 channels of analog input and output can be combined arbitrarily;
◆ 4-channel analog AD/DA channel uses FPGA parallel read and write non-MCU sequential read and write mode each channel analog delay <0.1ms;
◆ Each analog quantity reads high-speed sampling data through FPGA and the sampling rate is 20K times/second which is much higher than similar products in the market;
◆ Multimode fiber/single mode fiber is optional multimode can transmit 2KM single mode can transmit 20KM ST/SC/FC interface is optional;
◆ Signal failure protection function; display of electrical interface and fiber running status in all directions 4-20ma interface anti-radar to IEC61000-4-5 (8/20μS) differential mode: 6KV impedance (2Ω); common mode: 6KV impedance (2Ω) standard;
◆ Support wide range of AC and DC input support internal isolation redundant dual power input power supply overload protection anti-reverse protection;
◆ Super lightning protection function: lightning protection anti-induction high voltage anti-surge etc.;
◆ No fan to efficiently dissipate heat and reduce repair time;
◆ Provide DIN 35mm rail mounting or wall mounting mounting;
◆ Wide temperature type: working temperature -40 ° C ~ +85 ° C;
◆ All models are tested by 100% baking machine.
