The KSRC1-R-MTL is fitted into a compact protective enclosure.
Specifications:
Operation Frequency: 433MHz
Range: Up to 100metres line-of-sight - depending upon the transmitter selected.
Working Voltage: 12VDC
Standby Current: 6mA
Sensitivity: -102dBm
Contact: One Form C (Change-Over)
Maximum Contact Rating: 4 Amp 240VAC 3 Amp 30VDC (Resistive Load)
Case Size 40mm x 40mm x 25mm.

The KSRC4-1T1R-MTL Controller Set consists of a Key-fob 4 Channel UHF Transmitter with four control buttons and a four Channel UHF Receiver. A unique feature of the MTL series of controllers is that they offer three different, selectable,  control modes  M = Momentary - the controlled relay stays on onlt for the duration that the transmitter key is depressed.  T= Toggle - The controlled relay can be turned on with the first transmitter key depression and off by the second press (toggles)  L= Latched - This very useful function divides the receiver into two latchable sections.  The pushbuttons A and are used to latch and delatch two relays.  Pressing button  A latches Relay A and de-latches relay B. Pressing button B latches Button B and de-latches Button A.  In a similar fashion pushbuttons C and D can be made to operated relays Cand D

With these arrangement it is possible for operators to control up to 4 different items in various configurations.  Applications include controlling UP/Down counters in scoreboards, opening or closing of gates or windows, forward or reverse and  left right control of models. This unit may also be used in conjunction with PIR detectors, magnetic switches or pressure mats in wireless alarm systems.
