Intrinsically Safe Signal Converter for 4-20 mA Applications

Purpose: intrinsically safe transmission of current signal from the explosion-proof area to the explosion-proof area and support bidirectional transmission of signals via HART protocol. Intrinsic barrier type: active with galvanic isolation Signal type: current 4-20 mA with HART protocol Connection: 1 channel 4-20 mA analogue current input, 1 channel 4-20 mA analogue current output Conversion error: basic conversion error not more than ±0.1 per cent Time of setting of output signal after a sudden change of input signal: not more than 0,2 s Galvanic isolation: input, output, power supply, RS-485 interface - 2500 V Configuration and data exchange: via RS-485 interface with Modbus RTU protocol. Power supply voltage: 10-30 V Power consumption: not more than 2 W Explosion protection marking: [Ex ia] IIC/IIB/I Operating temperature range: -40°C to +70°C Overall dimensions (HxWxH): 99.4x22.5x109 Degree of protection: IR20 Warranty: 18 months
