Intrinsically safe side:

• Only RS485 (2-wire).

Non-intrinsically safe side:

• Jumpers-selected transmission type: RS485, RS422, RS232.

Power supply:

• 24V_DC.

Additional information:

• RS485 line released after 3 bd. Adapted to operate with receivers which do not keep a delay (imposed by the Modbus RTU standard) between received request and sent response.
• Transmission speed jumpers-selected: 9600, 14400, 19200, 38400, 57600, 115200. Automatic transmission speed measurement from set: 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 33600, 38400, 57600 bd. Other speeds will change the RS485 line releasing to 15-20 bd (as standard type S2Ex-RS-[ic]).
• Transmission parameters: 7N2, 7O1, 7O2, 7E1, 7E2, 8N1, 8N2, 8O1, 8O2, 8E1, 8E2.
• Explosion-proof construction designation:
  
  • II (3) G [Ex ic Gc] IIC;
  • II (3) D [Ex ic Dc] IIIC;
  • II 3G Ex nA II T4.
• Input, output and power supply circuits galvanically separated from each other.
• 1 channel in rail housing.
