Product Introduction

ADM-3142 can solve the fiber optic conversion of RS-485/422/232 serial port signals in industrial communication systems, and address the interference factors and long-distance transmission issues of RS-485/422/232 serial port signals in complex electromagnetic field environments.

The ADM-3000 series serial fiber MODEM can connect remote terminal units (RTUs) to hosts (HOSTs) or distributed data acquisition system (SCADA) controllers, and supports communication protocols such as PPI and MODBUS for PLCs. 35mm standard rail installation, wide voltage supply of DC9~48V, excellent performance and stable operation, fully meeting the system communication connection requirements in industrial environments.

Product Features

1. The fiber optic interface is a dual fiber SC port, which does not distinguish between single-mode and multi-mode fibers

2. Equipped with 2 RS-485 or 1 RS-422 or 1 RS-232 interfaces

3. When applied, one end can be RS-232 and the other end can be RS-485

4. Zero latency automatic forwarding, asynchronous transmission, point-to-point transmission

5. Automatically detect serial port speed, distinguish and control data transmission direction

6. RS-485 maximum communication rate 250Kbps, RS232 maximum communication rate 115.2K

7. The interface provides 600W surge protection and 15KV electrostatic protection

8. Wide voltage supply of DC9~48V, meeting the industrial 24V power supply requirements

9. 35mm DIN rail installation
