Interfaces

The Mini Switch Monitor is an interface within an entirely new housing. Designed in response to customer feedback, the smaller Mini Switch Monitor can be fitted onto a 35mm DIN-Rail with a twist-click motion or mounted in an enclosure such as a manual call pointIt is designed to monitor the state of one or more single pole, volt free contacts connected to a single pair of cables and to report the status to Apollo compatible control equipment

The Input/Output Unit provides a voltage-free, double pole changeover (DPCO) relay output, a single monitored switch input and an unmonitored, non-polarised opto-coupled input.

The Output Unit provides a voltage free single pole, changeover relay output. It is a simplified version of the Input/Output Unit without circuitry for monitoring inputs.Capable of switching up to 30V at 1AVoltage free, change-over relay outputShort-circuit isolatorCapable of switching up to 30V at 1AWall mounted (surface)Dimensions: 150x90x48mm

The Three Channel Input/Output Unit provides three voltage-free, single pole, changeover relay outputs and three monitored switch inputs
