Applications
- Heating power control: Controls heating elements through 16 digital outputs, with percent setpoint input and star connection with neutral conductor for single-phase loads.
Key Features
- 16 digital outputs: The heating-power section has 16 digital outputs, with a maximum of 1 heating element per output.
- Heating-power output: Output voltage is 230 V; power-carrying capacity is 40 W to 1 449 W per output at 230 V AC. For heating elements with high inrush current, the maximum is 750 W at 230 V AC.
- AC supply: Rated supply is 230 V AC, phase-neutral conductor, with 10 % relative negative tolerance and 10 % relative positive tolerance.
- Rack mounting and connections: The module uses screw mounting to a rack and has a 3-pole push-in spring-type terminal for supply voltage plus an 8-pole push-in spring-type terminal for heating and fan output.
- Diagnostics and monitoring: Functions include voltage diagnostics, fuse-blown, load-failure, Triac, rotating-field, communication, supply-voltage, line-voltage, frequency, and internal-temperature switch-off diagnostics. Temperature monitoring uses an NTC thermistor.
- Protection and isolation: Protection is IP20. Electrical isolation uses an optocoupler and/or protective impedance between the main circuit and PELV.
