RS definition of RoHS Compliance:
- The product does not contain any of the restricted substances in concentrations and applications banned by the Directive,
- and for components, the product is capable of being worked on at the higher temperatures required by lead–free soldering
The restricted substances and maximum allowed concentrations in the homogenous material are, by weight:
| Substance | Concentration |
| Lead | 0.1% |
| Mercury | 0.1% |
| PBB (Polybrominated Biphenyls) | 0.1% |
| PBDE ( Polybrominated Diphenyl Ethers) | 0.1% |
| Hexavalent Chromium | 0.1% |
| Cadmium | 0.01% |
| DEHP (Bis (2-Ethylhexl) phthalate) | 0.1% |
| BBP (Benzyl butyl phthalate) | 0.1% |
| DBP (Dibutyl phthalate) | 0.1% |
| DIBP (Diisobutyl phthalate) | 0.1% |
The supplier of the item listed below has informed RS Components that the product is "RoHS Compliant".
RS Components has taken all reasonable steps to confirm this statement. Information relates only to products sold on or after the date of this certificate.

Product Details
Mitsubishi Alpha 2
ALPHA 2 is an enhanced version of the existing ALPHA, achieving solutions that were not previously possible. With many powerful new features, it is ideal for building and smaller industrial automation applications. Key enhancements include a tripling of program capacity to 200 function blocks, two 1kHz high speed counters, an enlarged LCD display, I/O expansion options, extended operating temperature range and a second communications port.
Telemecanique Zelio 2
Smart Relay
Mitsubishi Alpha 2
Telemecanique now offers a new generation of expandable intelligent relays, offering substantial advantages in flexibility and functionality. Zelio Logic 2 Smart Relay is the optimum solution to control tasks such as automating small machines within industry, lighting, HVAC and access control within buildings.
With the small footprint, simple programming, powerful control functions and the possibility of changing or modifying the program in case of changed application requirements, it offers great savings in space and price compared to other options.
Choose between two new series - Compact and Modular. The Compact series is not expandable and is available with the following I/O block sizes: 10 I/O, 12 I/O and 20 I/O.
The Modular series is available with 10 and 26 I/O basic units and is expandable up to 40 I/O with the latter. Apart from this flexibility both new series are programmable using FBD, ladder and Grafcet SFC programming languages.
User friendly design for easy programming and operation, either directly from the module using the navigation buttons or via Windows based software.
New features
Fifteen new function blocks have been added to the instruction set, including mathematics calculations, and PWM and SMS text messaging. Providing new possibilities for analogue signal processing and automatic status reporting
An enlarged backlit information display screen with 4 lines each with 12 characters, features new options such as bar graphs and moving text displays
Each of the four DIN rail/panel mount base units can be expanded with a choice of one of four I/O expansion modules to give a total of up to 28 I/Os. The expansion modules available are: Four digital 24V DC inputs with two integrated 1kHz counters, 4 digital 240V AC inputs, 4 relay outputs and 4 transistor outputs
As with the earlier version of the Alpha, up to eight of the inputs on the base unit of the dc powered/input types can be configured as 0 - 10V analogue inputs. The resolution on the Alpha 2 has been improved to 20 mV (9 bits)
Operating temperature range has been extended from 0 to 55°C to -25 to +55 °C, with the same precision and reliability, making the unit suitable for enclosed outdoor use and refrigeration applications
A second communications port enables SMS text messages to be sent to mobile phones, e-mails to PCs and faxes in addition to using remote maintenance functions via modem. The control unit can also communicate with other controllers or peripheral components
Security can be ensured by three-levels of password protection to prevent unauthorised access to program and process variable data
The ALPHA 2 can be programmed directly using buttons on the front panel, but for significant improvements in programming speed and ease, ALVS programming software stock no. 443-3864 and cable stock no. 340-1939 is recommended. (See Alpha range for cable details and also panel mounting kits)
The starter kit stock no. 443-3820 offers a significant cost saving to get you started
Two new series: Compact and Modular
The Modular series is expandable up to 40 I/O points
The software includes ladder logic, Grafcet and FBD programming languages. (Up to 200 function blocks with 23 pre-programmed functions).
Large backlit easy to read LCD display (4 lines of 18 characters each)
Up to 10 years backup of data, date and time in the event of power failure
Automatic 1 hour clock summer/winter change.
16 up/down counters (0-9999)
1 fast counter
8 counter comparators
16 text blocks for viewing messages
28 auxiliary relays
8 week timers, depending on model
Up to 16 analogue inputs, depending on model
16 analogue comparators, depending on model
Plus
User friendly programming and operation using keyboard and LCD display or via Windows based software.
Powerful program simulator
Online monitoring
Choose between 24 V DC and 230 V AC supply voltage with analogue inputs available on some DC modules
DIN rail or panel mount
Menu driven display for easy navigation
Password protection
