ABB  DP820  dual-channel pulse counting module

ABB  DP820  dual-channel pulse counting module

Basic information
Product type: Dual channel pulse counting module.
Signal specification: 24V DC (12-32V DC).
Applicable pulse transmitter interfaces: RS 422, +5V, +12V, +24V and 13mA.
Associated module terminal units: TU810V1, TU812V1, TU814V1, TU830V1, TU833.
Electrical parameter
Rated insulation voltage: 50V.
Dielectric test voltage: 500V AC.
Power consumption: 2.5W.
Current consumption: +5V module bus 120mA, +24V module bus 0mA, +24V external 0mA.

Signal processing parameter
Input impedance: 2.5kΩ (digital input).
Isolation mode: Separate between channels and the common end of the circuit.
Frequency measurement error: Absolute relative error (including temperature drift) is (320 / measurement time x, in ms) ppm, (320 / measurement time x) + 100) ppm.
Counters: Each channel has counters and registers for position/length and speed/frequency measurements, and pulse counts (length/position) are performed by summating 29-bit bidirectional counters.
Frequency measurement range: 0.25Hz-1.5MHz.
Diagnostic function
Indicator: The front panel has LED indicators, including pulse (P), direction (UP), gating (ST), digital input (DI), synchronization (SY), digital output (DO), transmitter power normal (TP), etc., each channel has a status indicator, but also can indicate module error, module warning, channel error.

Mechanical parameter
Dimensions: Width 45mm, depth 102mm (including connector 111mm), height 119mm.
Weight: 0.15kg.
