About 1734-VHSC5

The 1734-VHSC5 is a product of Allen-Bradley. This module belongs to the POINT I/O product family of modular and compact Programmable Logic Controller (PLC) and Programmable Automation Controllers (PAC) that primarily support Allen-Bradley controller especially logix controller platform such as CompactLogix and ControlLogix. The 1734-VHSC5 has One (1) Ð 1 group of A/Aret, B/Bret and Z/Zret inputs, with input voltage of 5V DC along input current of 19.1 mA at 5V DC 25.7 mA at 6V DC. The input channelÕs maximum OFF state current is ² 0.250 mA and maximum ON state current of ³ 2.6V DC. The input channelÕs OFF state voltage is ² 1.25V DC and ON state voltage of ³ 2.6V DC and maximum ON state voltage of ± 6V. Each input channels has user selectable filter selections of Off, 10 _s, 100 _s, 1.0 ms and 10.0 ms. Input filters are used to eliminate processing of falsely triggered signals as well as line noise which may be interpreted as valid signals by the module. Caution must be applied when setting input filters as adjustment to lesser and higher sensitivity as both settings may reject valid signals and treated as noise. It is ideal to test the correct filter setting by observing the process response per setting. The module supports switching frequencies of 1.0 MHz counter and encoder X1 configurations 500 kHz encoder X2 configuration (no filter) 250 kHz encoder X4 configuration (no filter). It may be used to interface devices such as Encoders which can be single ended or differential, Pulse generators, Mechanical limit switches, metering devices and other devices with switching Frequencies up to 1 MHz. . The output channel has a rated output voltage range of 10É28.8V DC with OFF-state leakage current of ² 0.5 mA, ON-state voltage drop of ² 0.3V DC @ 0.5 A and ON-state current of 0.5 A max, Pilot Duty. The output channel is equipped with short-circuit current protection rated at 6A where Outputs are short-circuit protected and either cycle until you correct the fault or latch off (depending upon programming). Short circuit is detected when output turns on. It is also capable of detecting Open wire when output is turned OFF. Allen-Bradley module with catalog number 1734-VHSC24 is a POINT I/O module that functions as a The 1734-VHSC5 can be operated in Counter mode for reading single-phase pulse and return a binary count; Encoder mode for processing incoming Two-phase quadrature pulses and retunrs a binary count; Period/Rate mode used for counting internal clocks based on the ON period and returns a frequency; Continuous / Rate mode that continuously count during the ON period; Rate/Measurement mode where pulses are read during the sample period and returns a frequency and Pulse Width Modulation Mode (PWM) where a pulse is generated with modulated signal. The 1734-VHSC5Õs is a 24-Bit module. It counts in binary format with range of 0 to 16, 777,215 units. Accumulated count is stored to a 32-BIT register or 4 Words.
