Schneider Electric SR2 B121JD Zelio Compact PLC Module

This Zelio Logic module is a compact smart relay designed for simple control systems. The unit has 12 I/O (8x discrete inputs/4x relay outputs) and a supply voltage of 12V DC. The module comes with a large LCD screen that makes the system easy to use and also has an internal clock.

The module is easy to install and program using either FBD or LADDER and the Zelio Soft 2 programming software is intuitive to use. Zelio Logic smart relays are operationally versatile with test, simulation and monitoring modes along with excellent supervisory functionality.

Suitable for a wide range of simple control system applications carrying out tasks such as small machine control systems, decentralised control systems, lighting management, access control, control and monitoring, heating and air conditioning control, etc.

• Extremely compact
• May be DIN rail mounted
• Display is back-lit LCD 4 lines x 18 char x 1 row icons
• 6x Buttons for contextual navigation
• Zelio Soft 2 intuitive programming software
