The 6ES7132-7RD00-0AB0: SIMATIC DP electronics module for the ET200iSP intrinsically safe distributed I/O system. Four digital outputs rated at 23.1 V DC no-load voltage and 20 mA output current, with an internal resistor of 275 Ω that defines the loop characteristic for hazardous-area circuits.
Diagnostics and fault detection
Per-channel wire-break detection triggers when load resistance exceeds 10 kΩ or current drops below 100 µA. Short-circuit detection flags a resistance under 800 Ω on a single output, or under 40 Ω when outputs are paralleled. A parameterizable diagnostic alarm and a group error SF (red) LED provide annunciation without shutting down the rest of the rack.
