The PM645B is a multimode fiber optic communication module that supports multiple fiber wavelengths and data interface standards. Here are some of the main features and parameters of the PM645B:

Fiber interface: The PM645B supports multi-mode 850nm and 1310nm, as well as single-mode 1310nm and 1550nm fiber wavelengths. It is compatible with multiple transmission fiber types, including multimode 50/125um, 62.5/125um, 100/140um, and single-mode 8.3/125um, 9/125um, and 10/125um. In terms of transmission distance, multi-mode fiber can reach 2Km, while single-mode fiber can reach 20Km.

Data electrical interface: The module provides 1 to 2 5Pin terminal interfaces, which comply with the recommendations of the CiA organization and ODVA organization. In addition, it supports BUS standards such as CAN BUS/DeviceNet/CANOpen with communication rates up to 1M.

Power supply and protection: The PM645B uses dual power supply redundancy input, the voltage range is DC(9-36)V, and the typical operating voltage is DC24V. Its power consumption is less than 4W, and has DC1500V voltage isolation and reverse protection functions. In addition, it has an optional 120R terminal resistor built in and can be added by shorting the corresponding pin in the 5Pin data electrical interface.

Lightning and overcurrent protection: The module has 4000V lightning protection, as well as 1.5A overcurrent protection and 600W surge protection.

Mechanical characteristics: The PM645B has an outline size of 132mm105mm52mm (high depth and wide), and the housing is reinforced by wavy aluminum with IP30 protection grade. It supports 35mm rail mounting and has a net weight of 800g.

Operating environment: The operating temperature of the module ranges from -10 ° C to 70 ° C (-40 ° C to +85 ° C wide temperature is optional), the relative humidity does not exceed 90% (non-condensing), and the storage temperature ranges from -40 ° C to 80 ° C.
