The DSP-262 vehicle detector has been specifically designed to handle all traffic applications.
Working on virtually any size loop, the DSP-262 tunes itself automatically to the best operating frequency within the selected range. The DSP-262’s inherent noise filtering algorithms allow it to work reliably in any electrical situation.
With its easy to understand front panel switches and builtin flexibility the DSP-262 is the most “user friendly” detector on the market today.
Ordering Information
Standard part numbers are below:
DSP-262-x
x = S = 24 VDC, solid state outputs, timing (NEMA)
x = R = 24 VDC, relay outputs, timing (NEMA)
Sensitivity: Almost all traffic control applications can be handled with sensitivity set at NORMAL (level 4). The sensitivity DIP Switches (S1, S2, and S4) should rarely be moved from NORMAL. However, the Model 262 has seven sensitivity settings varying from a LOW of level 1 to a HIGH of level 7. Sensitivity 0 will disable the channel.
Sensitivity | S1 | S2 | S3 | DL% | Response Time (ms) |
0 | Off | Off | Off | Off | Off |
1 | On | Off | Off | .64 | 0.5 |
2 | Off | On | Off | .32 | 1 |
3 | On | ON | Off | .16 | 2 |
4 | Off | Off | On | .08 | 4 |
5 | On | Off | On | .04 | 8 |
6 | Off | On | ON | .02 | 18 |
7 | On | On | On | .01 | 32 |
Pulse / Presence: With this switch turned on, the main output will be a 125 ms pulse each time a vehicle enters the loop detection area. If the vehicle remains within the loop for two seconds, the detector will automatically retune, making itself ready for the next vehicle to arrive. If this switch is turned off the detector will output presence.
Delay: Delay is the interval between vehicle arrival and output activation. Delay time can be programmed from 0 to 63 seconds in one second increments. During the delay interval, the CALL LED is flashed slowly. If the vehicle leaves before the delay interval times out, the output will not occur.
Extension: Extension is the interval after vehicle exit and output deactivation. Extension time can be programmed from 0 to 15.75 seconds in quarter second increments. During this interval, the CALL LED is flashed rapidly. If another vehicle arrives before the interval times out, the output will not be dropped.
Frequency: One of four operating frequencies can be selected by using the front panel DIP switches: FREQ1 and FREQ2.
NOTE: Changing any DIP switch setting automatically resets the detector, which cancels the call output.
Fail Safe Operation: In the standard fail safe mode, the main output is normally energized and will de-energize for either of the following conditions: vehicle detection or loop failure. The relay version of the DSP-262 will place a call during power failure as well.
