INTERFACE Serial - Serial interface converters for industrial applications

Due to the increasing use of different kinds of automation techniques in all areas of industry, larger and larger amounts of data must be processed. More and more, serial data lines serve to control complex processes and detect process data, thus making them the "arteries" of these processes. A great variety of serial interfaces are used and they are often neither compatible with each other, nor do they meet the increasing requirements regarding resistance to interference, range, or rate of transmission.

PSM interface converters solve your transmission problems


INTERFACE Serial - Interface converters


The PSM-ME... product line was developed especially for the exacting requirements in a process environment - that is to say, in the control cabinet or junction box. The following versions are available for the different industrial applications:
  • RS-232 / RS-422 or RS-485
  • RS-232 / TTY (CL)
  • RS-232 / RS-232 and
  • RS-485 / RS-485.

The narrow 22.5 mm modules are simply snapped onto the DIN rails and at the same time automatically contact the shield discharge function. For a high degree of transmission reliability, the serial interfaces are also electrically isolated with high-quality 2 kV 3-way isolation.

Interface converter for all applications



INTERFACE SERIAL - Fiber optic (FO) converters


Maximum resistance to interference, constant availability, convenient diagnostics
Fiber optic data transmission in the industrial field has increasingly gained in importance over the past years. In particularly critical applications with very high requirements regarding availability it has become standard. This is due to the many advantages that fiber optic data transmission has over traditional copper systems. The main advantages are:
  • Maximum resistance to interference, even when exposed to extreme electromagnetic influences
  • High-grade electrical isolation between the stations
  • Maximum transmission distances of several kilometers with extremely high data rate
  • Maximum number of stations is not limited by the electrical properties of the communication interface used



INTERFACE SERIAL - Ethernet components - Factory line

Serial INTERFACE - Industrial modem


Remote diagnostics and maintenance for maximum system availability
The new rail-mountable RS-232 modem PSI-DATA/FAX... is specially designed for the industrial requirements of remote maintenance. It allows access to machines and systems anywhere in the world via point-to-point and dial connections following the V.34 standard. Comprehensive safety functions, e.g. presettable, selective call acceptance, password protection and call-back function prevent unauthorized access.

Particularly valuable for remote system monitoring is the configurable warning or fault warning input. When it is activated, the modem dials a freely defined telephone number and sends a saved text message as a fax or SMS. The modem is approved for operation in the public telephone networks in Europe, USA and Canada. Further certifications are possible on request.

This modem has been tested with the most common PLCs from various manufacturers and industrial PCs in numerous applications for remote maintenance.




INTERFACE SERIAL - Bluetooth data transmission


Wireless data transfer is particularly suitable for flexible and temporary data connections to changing communication modules or for addressing moving or mobile system components.

The international license-free radio standard BluetoothTMis suitable for applications in industrial environments. Depending on the system concept, it is possible to realize radio connections across distances of up to 150 m. This radio standard fulfill the requirements for interference-free data transfer via the so-called frequency hopping system (FHSS) in the 2.4 GHz ISM band. The permissible transmission capacity here is 100 mW (20 dBm).

Two different device designs are available based on BluetoothT. The Bluetooth converter PSI-WL-RS232-RS485/BT is the preferred solution in the control cabinet, using an external antenna, and is characterized by the following performance characteristics:

  • Mounting on EN mounting rail
  • Supply with 24 V DC or AC
  • Transmission rate up to 187.5 kbps
  • RS-232, RS-422, RS-485 adjustable
  • Supports all common 10/11 bit UART data formats
  • 3964R-compatible
  • Range up to 150 m
  • Protected Bluetooth access via password, fixed device pairing or device access list
  • Scalable transmission capacity (-28...20 dBm) for the spatial limits of the radio cell
  • Integrated Bluetooth path diagnostics show the signal quality of the wireless connection

The Bluetooth plug adapter PSI-WLPLUG... is already equipped with an integrated antenna. It is simply plugged onto the 9-pos. serial RS-232 port and supplied with 5 V DC via the separate plug-in power supply unit IBS-ECO-LINK... The transmission capacity is 0 dBm and this allows ranges of up to approximately 30 m. This adapter is preferred for temporary maintenance and diagnostics connections.

INTERFACE SERIAL - Quick mounting plug


Convenient connection system
The SUB-D connectors SUBCON can be connected fast and conveniently in field conditions without the need for soldering or crimping tools. The connector contacts are cleanly routed onto consecutively numbered screw terminal blocks.

High EMC shielding effect
The connector range SUBCON-.trimmed to the smallest dimensions provides high shielding against EMC influences in industrial environments by virtue of its metallic housing.

Optional cable infeed
The connection block can be inserted in either the upper or lower shell. This allows the cable to be fed in at 0° to 90° from right or left.

A wide product range
Irrespective of whether the application requires 9, 15 or 25-pos. connectors with one or two cable infeeds for point-to-point or RS-485 bus connections.
