Trip Amplifier

Application: Acts as an isolated intrinsic safety barrier interfacing NAMUR proximity sensors and dry mechanical contacts located in hazardous / explosive areas.

Key Features:

• Amplifies micro-current signals from NAMUR sensors into robust relay contact outputs
• Galvanic 3-way isolation between input, output, and power supply
• Line fault detection (LFD) for wire-break and short-circuit monitoring
• Ultra-slim DIN-rail housing saving cabinet space
• Supply options: 230V AC, 110V AC, or 24V DC

Application: Dual-channel monitoring for hazardous area switches, dual NAMUR sensors, and safety interlocks in chemical, petrochemical, and gas plants.

Key Features:

• Two completely independent isolated channels in a single mid-size housing
• Dual changeover relay contacts (SPDT / DPDT) rated for 250V AC / 2A
• Selectable direction of action (high trip / low trip / inverted) via DIP switches
• Front-panel LED indicators for channel status, alarm trip, and power
• Operating temperature: -20°C to +60°C

Application: Industrial process automation requiring limit value alarms from analog signals (4-20mA / 0-10V) or temperature inputs with potential-free relay switching.

Key Features:

• Configurable set-point trip levels with adjustable hysteresis
• High switching reliability with potential-free changeover contacts
• Wide range power input: 24V DC or universal 85-265V AC/DC
• Removable screw terminal blocks for quick wiring and maintenance
• High electrical noise immunity meeting industrial EMC guidelines
