The power output modules are an important component of the heater control.
Three different power output modules can be used depending on the application:
- LA724I – the universal version:
24-channel power output module for an output of up to 1,150 W per channel - LA724I HP – the high-power version:
12-channel power output module for voltages up to 400 V/max. 10 A per channel - LA724I SSR – the high-current version:
24-channel power output module for controlling external solid-state relays SSR (up to 90 A/load)

LA724I SSR power output module
- Robust, industry-standard design (metal enclosure, small footprint)
- Distributed structure without enclosure possible
- 4 diagnostics LEDs for indicating channel/module faults
- Internal parallel bus interface
- Connection of the phases via conductor rails
- No settings have to be made on the power output modules.
