Specifications
Input data
Inputs | 0(4) ... 20 mA，0 ... 50 mA |
Operating current | <2 µA |
Voltage drop | Approx. 1.2 V (20 mA) |
Approx. 1.6 V (50 mA) |
Overload | 100 mA, 20 V |
Output data
Output | 0(4) ... 20 mA/max. 15 V (corresponds to 750 ohms load) |
0 ... 50 mA/max. 15 V (corresponds to 300 ohms load) |

Residual ripple1) | <1.5 mVpp / mA |
Transmission behavior
Transformation error 2) | 0.02 % meas. val. |
Load error | <0.02 % meas. val. per 100 ohms |
Rise or fall time | Approx. 2.5 ms at 500 ohms load resistance |
Isolation
Test voltage | 2.5 kV AC |
Working voltage (basic isolation) | 500 VDC across any inputs and outputs with overvoltage category II and pollution degree 3 according to EN 61010-1 (with type 41 A2/3 between neighboring inputs and outputs with pollution degree 2 inside the housing, degree 3 outside). For applications with high working voltages, you should ensure there is sufficient spacing or isolation from neighboring devices and protection against electric shocks. |
