Product description The outputs can be switched by means of standard registers via a Modbus master. Module address, bit rate and parity are set by means of two address switches on the front or by software.
With strong inductive loads, we recommend protecting the relay contacts additionally with an RC element. The module is provided with a manual control for manually switching the relays.
Suitable for decentralized mounting on DIN TH35 rail according to IEC 60715 in electrical distribution cabinets.
