High-Capacity Relay Outputs for Switchgear Control

The Siemens 6MD1022-0AA00 provides 16 relay outputs rated at 250V AC and 5A continuous. This high capacity suits direct control of circuit breakers and contactors. Each relay makes 30A for 100ms during initial energization. The module breaks inductive loads up to 2A for motor and coil applications.

Fast Response for Critical Switching Operations

This command output module achieves switching times of 10 ms for both operate and release. This rapid response meets the demanding timing requirements of protection schemes. The relays maintain consistent performance across their mechanical and electrical life. Mechanical life reaches 10 million operations for long-term reliability.

Comprehensive Channel Diagnostics and Status

Sixteen yellow LEDs illuminate when each output channel receives an active command. A green module OK LED confirms proper power and communication status. This visual feedback helps operators verify output states quickly. The module stores diagnostic data in EEPROM for fault analysis.

Individual Fuse Protection per Channel

Each relay output includes a replaceable 2A fast-blow fuse for short-circuit protection. This per-channel fusing prevents a single fault from disabling multiple outputs. Users can replace blown fuses easily without removing the module. The fuses protect both the relay contacts and the downstream wiring.

Latching and Non-Latching Relay Options

The module supports both latching and non-latching relay configurations. Latching relays maintain their state without continuous coil power for energy efficiency. Non-latching relays provide fail-safe operation by de-energizing on power loss. Users can configure each channel independently through software parameters.

Robust Mechanical Construction for Substation Environments

The module measures 185 x 145 x 40 mm and weighs 0.55 kg for stable installation. Two 20-position screw-clamp blocks accept wires from 0.2 mm² to 4 mm². The IP20-rated housing protects internal components from dust and accidental contact. The unit operates reliably across -25°C to +70°C for harsh substation conditions.
