C1-45 – RS485/422 repeater.Power 9-36Vdc.Optically isolated Low Profile
C1-45 ensures the regeneration of the signals on RS422 or RS485 standard, allowing to overcome the limits imposed by the law on cable length and the number of devices. The insertion of a device, allows you to extend the RS485 or RS422 over the maximum allowed distance of 1200 m.for each repeater , C1-45 does not introduce appreciable delays or distortion in the signals.C1-45 is used to expand the coverage area of the transmitted signals to RS485 or RS422 ensuring transmission quality far better than wireless technologies.
No drivers to load
The device does not need any driver software to be configured.
Both side termination
User can set by microswitches : termination and bias resistors independently in the 2 sides of the line.
The model C1-55 function as a concentrator / expander from 1 RS485 into two sections RS485.Via DIP switches you can set: line type (RS422 or RS485), baud rate (from 1.2 to 115 kbit / s) and terminating resistors and polarization.
A triple optical isolation galvanically separates the power supply section from the two sides of the line.
Although installed in locations difficult to access, these devices once put into operation don’t need any assistance (power on – off, reset, etc..) to ensure proper operation (technology “no-stop” based on hardware watchdog).
