Technical Parameters Category Specification Model MTL5575 Product Type Safety Relay Module / Safety Loop Monitor Typical Safety Standard IEC 61508, IEC 61511 (SIL 2 capable) Input Channels Typically one or two Dual-channel inputs (for monitoring E-Stop circuits etc.) Input Type Dry contacts (volt-free contacts) from safety devices. Outputs 3 C/O (Changeover) relays - 2 "Auxiliary" and 1 "Safety". Contact Rating Typically 8 A, 250 V AC / 5 A, 30 V DC (resistive) Supply Voltage 24 V DC (nominal), with a wide operating range (e.g., 19-32 V DC). Key Features Fault Detection Yes. Automatically detects cross faults, earth faults, and loss of supply. Reset Modes Manual, Automatic, or Monitored reset (selectable). Status Indication LED indicators for Power, Inputs, and Faults. Safety Integrity Level Suitable for SIL 2 applications (as per specific safety manual). Operating Temperature -40°C to +70°C (standard for industrial MTL products). Mounting Standard 35 mm DIN rail. Safety Function Upon a valid input signal or detected fault, it de-energizes the safety relay, breaking the circuit to the controlled device.
