This product is part of the Harmony control relays range, an offer of Near Field Communication and conventional control relays (formerly known as Zelio Control Relays). The temperature controller features 11-segment 5-digit LCD display. It is a modular measurement and control relay with a rated supply voltage of 100V to 240V AC. It offers thermocouple, RTD, DC voltage or DC current analogue inputs and 2 relay outputs with normally opened contact. It also has 1 changeover contact alarm output. The relay outputs are rated to 250V AC/3A on resistive and 250V AC/1A on inductive loads. This Zelio temperature control relay features auto tuning and PID functions. It is an IP66/IP20 and NEMA 4X rated product. Its outer dimensions are 48mm (height) x 48mm (width). It weighs 120g. It is suitable for packaging, industrial machines, textiles and HVAC applications. This product is certified by CURus (873). It meets EN 61326-1, EN 61010-1 and CSA C22.2 No 24-93 standards. It supports 1/16 DIN panel mount. The RTC48 temperature controllers are key components for temperature regulation solutions. These control relays monitor and detect abnormal operating conditions.
