This product range from PR electronics is used to measure e.g. flow in the food industry and frequency on offshore oilrigs. This is the range of frequency and pulse modules:

The 2200 series

The 2255 and 2288 for DIN rail mounting with 11-pole socket constitute the 2200-series. The front key configurable 2255 is designed for f/I – f/f conversion. The functional module 2288 is specifically designed for pulse inversion and can be programmed via DIP-switches. Additionally, both modules are suitable for pulse stretching, so that the signal can be adapted to the PLC.

The 4000 series

The 4222 is a DIN rail mounted I/f converter which is programmed by way of the detachable programming interface 4501. The 4501 guides the user through all the configuration steps via scrolling help texts.

The 5000 series

The 5000 series consists of several universal frequency and pulse modules that can be configured in PR electronics’ own windows-based program PReset. The following modules are part of the 5000 series:

• 5223A and 5225 are both universal, programmable f/I – f/f converters
• 5225 is similar to 5223A apart from the concurrent f/I – f/f conversion function

The complete range of frequency and pulse modules is ideal for:

• Speed measurement
• Pulse division
• Pulse stretching
• Pulse inversion
• Frequency generating
