Legislation and Compliance
RoHS Certificate of Compliance
EU Directives 2011/65/EU and 2015/863 restrict the use of the 10 substances below in the manufacture of specified types of electrical equipment.
Whilst this restriction does not legally apply to components, it is recognised that component “compliance” is relevant to many customers.
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
Interface Converter RS-232/RS422, RS-232/RS-485
From Phoneix Contacts, the DIN-Rail mounted PSM-ME-RS232/RS485-P Interface converter is designed to convert RS-232 interface signals bi-directionally to the RS-485 and RS-422 standard. The robust dual-channel converter is a category 3 device designed for installation in zone 2 potentially explosive areas. It meets the requirements of EN 60079-0:2012+A11:2013 and EN 60079-15:2010.
Featuring diagnostic and status indicator LEDs for supply voltage and RS232 data reception and transmission. The PSM-ME-RS232/RS485-P Interface converter offers the user the flexibility to meet the many demands of today’s industrial applications.
Programming
The PSM-ME-RS232/RS485-P signal conditioners are configurable dip switches and slide switches, accessed via opening the housing and sliding out the PCB.
Features and Benefits
• RS-422 4-wire point-to-point operation
• RS-485 2-wire operation, half-duplex
• RS-485 4-wire operation, full-duplex
• Automatic RS-485 transmit/receive changeover
• Transmission speed of 4.8 kbps to 115.2 kbps
• Integrated data indicator for dynamic indication of transmit and receive data
• High-quality 3-way isolation between the power supply, RS-232, and RS-422/RS-485
• Integrated surge protection with transient discharge to the DIN rail
Application Examples
RS-232 to RS-485
The RS-485 standard is employed where more than two devices need to communicate with each other. By converting the RS-232 point-to-point interface to the bus-capable RS-485 standard, up to 32 devices may be networked via a 2-wire cable (semi-duplex) or 4-wire cable (full-duplex).
Possible applications:
· RS-232 master adjustment
· Programming/parameterization connection
· In networking RS-232 devices, the software must ensure devie addressability
RS-232 to RS-422
The RS-422 interface is an interface for point-to-point connections.
Possible applications:
· Interface adaptation to RS-422 devices
· Point-to-point connections of up to 1200 m; for range increase and interference-free transmission of RS-232 signals
