Omron E5DC-RX2ASM-802 Digital Temperature Controller
The Omron E5DC-RX2ASM-802 Temperature Controller is a compact and precise Digital Temperature Controller designed for stable, fast-response industrial temperature control. Its 22.5 × 96 mm DIN Track-mounting design supports a versatile 1 point input for accurate sensing across various temperature applications. Operating on 100 to 240 VAC, 50/60 Hz with an allowable range of 85% to 110% of rated supply voltage , it provides ON/OFF or 2-PID control with auto-tuning for consistent temperature stability. The controller features Relay output, 2 auxiliary outputs, and a bright 11-segment digital display for clear visibility. Its Screw Terminals wiring system ensures quick installation and easy maintenance, while its removable terminal block simplifies replacement. Designed for efficient connections to HMIs and PLCs Manufactured by Omron, part of the Omron Temperature Controller ecosystem within the Omron E5DC Series.
