TX 100

Product Description

TX-100 Trip Amplifier is a compact single-input, dual-trip output device designed for reliable process monitoring and protection in industrial applications. It supports universal inputs including RTD, thermocouple, current (4–20 mA), and voltage signals, ensuring high application flexibility. The unit provides isolated analog output (4–20 mA or 0–5 V) along with two potential-free relay trip outputs for alarm or control action. A bright 4-digit red LED display offers clear indication of process values and engineering units. With high isolation of 1.5 kV, fast response time, and DIN rail mounting, it ensures safe and dependable operation. Optional RS-485 MODBUS RTU communication enables seamless integration with automation systems.
