Eltako MSR12-UC electrical relay Blue

Multifunction sensor relay for brightness, twilight, wind, rain and frost, 5 OptoMOS semiconductor outputs 50 mA/8..230 V UC.
Standby loss without Multi sensor MS 0.5 watt only.
Modular device for DIN 60715 TH35 rail mounting.
2 modules = 36 mm wide, 58 mm deep.
The multi-sensor relay MSR12-UC evaluates the signals from the multisensor MS once per second, and sends appropriate control signals to the downstream EGS12Z-UC or EGS12Z2-UC actuators depending on the setting of the rotary switch on the front.
The OptoMOS semiconductor outputs switch the voltage applied to the universal voltage input terminal +B1. Only a single Multisensor MS can be connected to a Multifunction sensor relay MSR12-UC. Several MSR12-UC can be connected to a multisensor MS, e.g. for evaluating up to three directions with the light sensor of the MS. Only a single MSR12-UC must provide the outer terminal resistance. It must be removed if there is a further MSR12-UC. Supply voltage 24 V DC from power unit SNT12-230 V/24 V DC (chapter 17). This power unit simultaneously supplies the multisensor MS connected to the terminals MS1, MS2, MSA and MSB, including heating of the rain sensor surface. After installation wait for the short automatic synchronisation of approx. 1 minute. During this process three LEDs fl ash in a slow sequence.
