QL1, Quick-Link universal relay module

The Quick-link is a simple but extremely versatile relay module comprising of input coil connections to isolated output contact connections - self contained into a plastic enclosure. Termination's are by screw terminals & an LED shows when the relay coil is energised. Various coil voltage options are available & the DPCO contacts have the option of fitment of snubber network capacitor + resistor across either the N/O or N/C contacts!

Depending on coil options these modules can be used to safely switch mains power from a low voltage feed or switch low voltage devices from a high voltage mains feed. Low current feeds can be 'converted' to high current.DPCO relay contacts enable inversion if required i.e.; turn on when coil is off.

Many applications are possible, these modules provide a quick & safe solution to link systems together without resorting to custom built 'black boxes'.

Coil options
6, 12, 24, 48, 60, 110VDC
6, 12, 24, 48, 60VAC

MDU-14-ET External Trip Unit

All of the features of our MDU-14 standard professional unit with the addition of a highly versatile external trip & manual reset feature! Auto reset mode enables unit to be remotely powered up & down. Fully featured yet simple to setup & use gives this MDU incredible flexibility.

For situations where over-current protection by its self is just not enough, over/under temperature, over/under pressure - you name it, this unit can do it! This is a product waiting for applications!

Applications
Test set-ups
Fire alarm, emergency power shutdown
Process control
Lighting control
Audio systems

External Trip (manual reset)
Sensors can be temperature, thermostat, pressure, light, Pir, sound, proximity, position, fire alarm - (or any combination) in fact any type can be used to safely shutdown power when predefined limits are reached! Manual intervention is then required to restore power to equipment.

Remote Control (auto reset)
This features allows power up & down from a wide variety of sources such as PCs, timers, remotely located switches, fire alarm panels, etc.

Sensor types
Sensors can be closing contact n/c, or n/o operation. Alternatively low voltage DC feed either volts present to switch on, or volts present to switch off.

Manual reset
Manual reset intervention is by front panel located push-button switch or remotely located push-button switch. This function is redundant when operating in auto reset mode.
