Product Introduction
ABB YPH108B is a measurement board used in the field of industrial automation. It is usually available in models such as YPH108B/SPC. It is mainly used for high-precision measurement, and can achieve accurate monitoring and control of physical quantities such as temperature, pressure, and flow. It can also be used for speed measurement to provide reliable data acquisition for industrial automation systems. Equipped with an RS-485 Modbus communication interface, it is easy to connect to the existing industrial network and enhance system integration capabilities.

Product Details
YPH 108B Functional blocks:
-Interfaces for the 2 incremental encoders with 3 fast optochannels and a synchronizing binary input
-Pulse and time counter ASICs (IEI)
-PLD circuit for
control logic
status registers
configuration registers
-2 analog outputs
-Crystal oscillator for the time base clock (32 MHz).
Two incremental encoders can be connected to the card, each of them having 3 optoisolated fast input channels: CHA, CHB, CHZ, and
an optoisolated binary input for synchronizing. The incremental encoder inputs can be connected to be either single-ended inputs or differential mode inputs. The input mode (encoder type) selection is made with the coding straps.
The incremental encoder input signals are filtered so that the maximum input frequency is 300 kHz.
There is software selectable filtering for the quadrature decoder inputs CHA and CHB to remove edge oscillation interference.
There are two basic types of Speed Measuring Board YPH 108B: YPH 108B/GP and YPH 108B/SP.
The YPH108B/GP board provides two incremental encoder interfaces for speed and position measurement, two inputs for synchronization, and two analog outputs.
The YPH108B/SP board provides the same features as the YPH108B/GP board and, in addition, it has 4 programmable 16-bit counters with load and hold registers, 4 digital inputs, and 4 digital outputs. The counters and their registers can be configured in various ways to count external or internal pulses (i.e., length, angle, time, etc.) in applications where greater accuracy is needed.
The inputs of both boards can receive 5 V signals from single-ended pulse encoders as well as signals from differential pulse encoders. High-frequency signals from single-ended encoders can, however, suffer from timing delay if the pulse encoder cables are long and if the encoder has a low driving capacity. This is because the falling edges of the signals are not received separately. In such a case, use board types YPH 108B/GP/GPC and YPH 108B/SP/SPC.
There are also Speed Measuring Boards YPH 108B/GP/GPC and YPH 108B/SP/SPC, which functionally correspond to types YPH108B/GP and YPH 108B/SP, respectively, but which are equipped with capacitors.
The inputs of these boards can receive signals from both single-ended and differential pulse encoders with equal timing accuracy, provided that the capacitor input is used for 12 V and 24 V single-ended signals. Note the jumper settings. The capacitor input cannot, however, be used for 5 V single-ended signals.
