Schneider Zelio Smart Relay 24Vac 12 In 8 Out
Zelio SR2B201B (12 inputs, 8 outputs) programmable
Zelio Logic smart relays are designed for use in small automated systems. They are used in both the industrial and commercial sectors.
For industry: automation of small finishing, production, assembly, or packaging machines, small automated systems operating at 48 V a (hoisting application, etc.) , decentralized automation of ancillary equipment for large and medium-sized machines (in the textile, plastics, materials processing sectors, etc.), automation systems for agricultural machinery (irrigation, pumping, greenhouses, etc.)
For the commercial/building sectors: automation of barriers, roller shutters, access control, automation of lighting systems, automation of compressors and air conditioning systems etc. Their compact size and ease of setup make them a competitive alternative to solutions based on cabled logic or specific cards.
Programming Simple programming, backed up by the universal nature of the languages, meets the requirements of automation specialists and the needs of electricians. Programming can be performed: locally, using the buttons on the Zelio Logic smart relay (ladder language), on a PC using “Zelio Soft 2” software
When using a PC, programming can be performed either in ladder language or in function block diagram (FBD) language (see page 10). The LCD display unit backlight (1) is activated by pressing one of the 6 programming buttons on the Zelio Logic smart relay or by programming with “Zelio Soft 2” software (e.g. flashing when diagnosing a malfunction). The clock has a lithium battery, which gives it an independent operating time of 10 years. Data backup (preset values and current values) is provided by an EEPROM Flash memory (with the same lifetime as the smart relay).
