RTR-505-P Counter and pulse input recorder



RTR-505-P/RTR-505-PL is a data logger designed to record changes in the pulse count for contact signals (such as switches, relays, and thermostats) and the Lo / Hi voltage signals that occur during a set recording interval. It is also capable of recording the total count of pulses from the beginning of the recording.

Model RTR-505-PL includes a Long Life battery.

Includes Input Cable PIC-3150: Pulse Count 1ch
- Pulse Count: 0 to 61439
- Input Signal: Contact Input / Voltage Input

The TandD RTR-505-P is a Data Logger designed to record the changes in pulse count for contact signals (such as switches, relays, and thermostats) and Lo / Hi voltage signals that occur during a set recording interval. It is also capable of recording the total pulse count from the start of recording.

Download Data via Wireless Communication with a Base Unit

Recorded data can be downloaded from the RTR-505 data logger (Remote Unit) via wireless communication with a Base Unit. The wireless communication range between a Remote Unit and a Base Unit is about 150 meters [500 ft]. By registering an RTR-500 as a Repeater, it can be used to expand the wireless communication range.

Large Logging Capacity: Up to 16,000 Readings

16,000 readings means you can record every one second and still log four and a half hours of data; or at a recording interval * of 60 minutes you can keep logging for 666 days. A Base Unit can download via wireless communication one RTR-505 Remote Unit at full logging capacity (16,000 readings) in about two minutes.

Low Energy Consumption Design

The RTR-505 Data Logger uses one Lithium Battery (LS14250). At normal temperature, if recorded data is downloaded once a day or if monitoring is carried out once every ten minutes, the estimated battery life will be about ten months. Model names which include "L" are designed with a large capacity battery pack. Under the same conditions, L-type models will continue for about four years without the need to change the battery.

Battery life varies depending on the type of battery, the measuring environment, and the frequency of communication. All estimates are based on operations carried out with a new battery and are in no way to guarantee of current battery life.
