PEM-Expansion Modules

PEM I/O Expansion Modules

P iciorgros Radio RTU Modules each have an I/O expansion interface (Intel BitBus) through which up to 16 PEM I/OExpansion Modules can be bus-connected.With this, radio RTU stations can be configuredwith a large number of on-off inputsand outputs, analog inputs and outputs, and pulse inputs.

On-off input and output states are indicated by LED lamps on the front face of each module. On-off inputs and outputs are opto-isolated.

Analog inputs and outputs are electrically isolated using switched-capacitor analog isolators. It is nevertheless preferable that external isolation amplifiers be used with analog I/Os, and isolating relays with on-off I/Os.

All PEM I/O Expansion Modules can operate on 9.6 to 28.8 VDC supply, with the exception of the UCL--EM-04AO Analog Output Module.
The modules are housed in DIN rail mounting enclosures with tough extruded aluminum bodies and plastic end caps internally laminated with aluminum foil shielding.

PEM Modules are rugged industrial-duty products that can operate at temperatures in the range of -20ºC to +70ºC and tolerate wide supply voltage variations.

PEM-NT24 Power Converter Power Converter module for I/O Expansion Module If the available power supply is 24 VDC, then a PEM-NT24 Power Converter is required for providing the required voltage to the Expansion Modules.
Timeserver PTS-100 Der PTS-100 dient zur Erzeugung eines DCF-77-Zeitsignals aus unterschiedlichen Referenzquellen und zur Verlängerung der Standby-Zeit der Zentralfunkgeräte TRM, RTU und MDP bei Ausfall der Referenzquellen. Referenzquellen für das Zeitsignal sind: • GPS (Global Positioning System), GPS-Antenne im Lieferumfang enthalten • DCF-77, (aktive DCF-77-Empfangsantenne ist optional erhältlich. • RTC (Real Time Clock) integrierte Echtzeituhr für Ausfall sämtlicher Quellen.
