Product Specification

  • Board Input Voltage: 12V DC or 24V DC (You can power this kit directly from a lead acid battery thanks to it’s inbuilt regulator and polarity & line stabiliser circuits)
  • Logic Voltage / Control Input Type: NPN Sensor, NO or NC
  • Precision programmed with enhanced clocking (allows you to set any time delay between 0 seconds and several days in blocks of either seconds, minutes or hours. Unlike many cheaper alternatives, the timer’s accuracy will not be affected by thermal conditions such as ambient temperature and you don’t have to guess what it is set to, you can have exactly 10 seconds delay for example.
  • Ability to have the timer continue monitoring the sensor and reset the program accordingly or you can have it ignore the sensor until it has finished counting down the timer’s delay.
  • Indicator LEDs show what the board is doing, power coming in, logic / program status and relay state (channel state).
  • The board can be built with a ‘beeper’ to give an audible beep on certain events / state changes (by prior arrangement)
  • We can customise the programming on the device (subject to an additional cost but out rates are quite reasonable).
  • Switching Form: SPDT (Normally Open, Common, Normally Closed)
  • Switching Power (Amps): 10 Amperes (10A @ UP TO 30V DC or UP TO 250V AC)
  • Switch Response Time (ms): Varies depending on time setting and mode, ‘instant mode’ reveals a response time of around 12ms maximum.
  • Protection Features include flywheel, optical isolation, reverse connection protection, surge suppressor, line regulation, and short-circuit protection on sensor.
  • Board’s Dimensions (L x W x H)   8 cm (+ 1.5 cm for pluggable terminals) x 5 cm x 1.8cm
  • No Soldering Required (We assemble and test it all for you
  • PCB Type: Industrial Grade FR-4, does not flex or corrode.
  • Treatments: HASL SMO Silicone Moisture Barrier
  • Place of Manufacture: ENGLAND – Hand Made & Tested on site.
  • Quality & Safety Control: CE, EMC, IEC 6100-6-1, 6100-6-3, RoHS, WEEE (Compliance Number WEE/FK 2902 UZ), IMS115
  • Safety Notices: Take care when working with high voltages, isolate before touching the unit. This device can be used to switch mains power and if using this it should be installed by a qualified electrician. Wiring is extremely simple and requires only a few minutes to wire your devices in to it.
  • VAT: Yes, inclusive at standard rate. A VAT invoice will be available on request
  • Quantity: This listing is for 1 unit unless otherwise stated, the pictures are a true representation of the quality but more than one item may be shown in the picture for multiple angles. This is illustrative only.
  • SENSOR:  2m Reflective Photoelectric Beam Sensor with Baffle board (Reflector) the sensor should be positioned directly opposite the baffle board at a distance of no more than 2 meters. Please note that steam, smoke / fog and condensation can affect the performance of light sensors and may shorten the detection range or cause false readings so if you are wanting to install the sensor anywhere that it may be exposed to smoke, fog or condensation we advise you to contact us first to check compatibility.
