A Safe Way In Automation
GA-2101+
Data Intrinsic Safety Barrier
GA-2101 barrier is a communication bridge that sits between EVCDs or correctors and controllers like PLCs and RTUs. It can communicate with a hazardous area via three RS232 and one RS485 serial port. And it can transfer the collected data to the safe field through a two-port RS485 interface. The most significant feature of this device is that all these information exchanges are done through MODBUS, with a bit rate of up to 115.2 kbps via the previously mentioned serial ports. This makes the B-2101L+ barrier ideal for convenient, remote monitoring from a safe area.
The B-2101L+ barrier is able to make contact with common corrector vendors such as the VemmTech, RMG, and Course. However, it can also communicate with other corrector vendors outside of this list, by defining a custom device with the RS485/ RS232 MODBUS RTU standard.
The SAG B-2101L+ barrier has an operating temperature of -20 to +60 °C, a 24V DC power supply, and is able to power four isolated safe voltage channels in the range of 0-9 volts.
