For connection and galvanical insulation of devices with interfaces RS232, RS485, RS422 (RS485F) and current loop.
Common technical features:
- Own power supply 230 VAC, built-in overload protection.
- Three-way galvanic insulation.
- Baud rate - up to 125 Kbps.
Specific technical features:
- ISO485DR-B, REP485DR-B, REP485DR-C - automatic send data control.
- ISO485DR-B - Plug & play insulator and converter of RS232 – RS485/422 interfaces.
- ISORS422-C – control of transmission direction by RTS signal in half duplex mode, no transmission direction control in full duplex mode.
- REP485DR-B – Plug&Play repeater, extends the line / increasing the number of the devices in the RS485 network.
- REP485DR-C - extends the line / increasing the number of the devices in the RS422 network.
- ISORS-CL - an active device, feeds the current loop, capable to operate from 4 to 54 mA. No control of the data transmission direction.
- ISORS422-C, ISORS-CL – cable are leaded via cable glands.
