Came magnetic induction loop detector, 2-channel, 230 V

The Came SMA220 (009SMA230) is a version of the 2-channel loop detector that you power directly from the 100–240 V AC mains. It is suitable where you do not have a 24 V supply in the distribution board. The detector evaluates two induction loops in the road surface and switches the output relay when a metal vehicle is present.

Functions

• Modes – gate, barrier, closed-circuit or direction logic according to the order in which the vehicle passes over the loops.
• Outputs – 2 relays (max. 240 V AC / 2 A or 30 V DC / 1 A) and an optional fault output.
• Settings – with the Mode and Data buttons: time functions, 9 sensitivity levels, ASB function and 4 frequencies.

Things to bear in mind before installation

• Power supply – 100–240 V AC, 50/60 Hz, power consumption max. 2.9 VA. Only connect it with the power off.
• Location – 35 mm DIN rail in a distribution board, protection rating IP20.
• Loop and feeder – inductance ideally 80–300 µH, resistance including feeder below 8 Ω, feeder twisted at least 20 times per metre. The site preparation diagram is in the attachment.

The 24 V AC/DC version is the Came SMA2; for one loop, the Came SMA. You will find barriers in the road barriers category. Send any questions to eshop@saver.sk; for wiring in the Košice and Prešov regions, see the section.
