This document describes the features and characteristics of Carel products, including power requirements, input/output types, measurement accuracy, etc.
This manual provides the complete electrical specifications for the Carel MAC2SER000 controller, covering power supply requirements, analogue and digital inputs and outputs, PWM and relay functions, as well as environmental limits and protection ratings. It also includes wiring diagrams, connector details, and installation templates.
Key data include a 24Vac ±15% power source, 200 mA current absorption, 800 mA slow‑blow fuse, 10 digital inputs (5 mA each), 3 NTC temperature inputs, a 0‑10 V analogue output (10 mA load), PWM output at 4.8 V ±10%, and IP55 front‑panel protection. Operating temperature ranges from –30 °C to 70 °C with humidity up to 100 % rH. This manual is written in Chinese.
