Key Features

• Integrated Transmitter Power:​ The /LP suffix​ provides a built-in 24V DC power supply for 2-wire transmitters (4-20 mA), eliminating the need for an external power source in the loop.

• High-Density Alarm Logic:​ Supports up to 9 configurable relay outputs (3 standard) with advanced functions like deviation, PV high/low, and latch for complex alarm sequencing.

• Universal Input Flexibility:​ Pre-configured for a wide range of signals (TC Types K/J, Pt100, 0-10V, 4-20mA) without requiring hardware changes.

• Space-Saving Design:​ 65mm shallow depth allows installation in slim control panels and crowded instrument racks.

Applications

• Process Alarm Annunciator:​ Monitoring critical process variables (pressure, temperature, flow) with visual indication and relay-based alarm tripping.

• Transmitter Indicator:​ Serving as a local display and isolator for 4-20 mA loop-powered pressure or temperature transmitters using the internal 24V LPS.

• Batch Process Control:​ Providing setpoint and deviation alarm functions in chemical, pharmaceutical, and water treatment control rooms.
