Description

For new orders please refer to BPLS257
The BPLR255 is for applications where a pulse isolation is required. The input pulse is repowered and repeated up to a maximum frequency of 10kHz up to 50kHz for pulse follower. The output pulse width is adjustable (SPAN) to provide “pulse stretching” where the input pulse is very short. Input signals of various types or from a variety of sensors can be accommodated:Low level AC, sine waves as produced by coil-type pick up (min 200mVpp). Low level AC, any wave shape having a consistent frequency pattern (200mVpp up to 20Vpp).DC pulse, (200mVpp up to 50Vpp). NAMUR proximity sensor or pulsing contact– the sensor is directly connected to the BPLR155 as the module provides the 8Vdc auxiliary supply. All types of 3-wire proximity sensors, optical sensors or any devices with NPN/PNP open collector transistor output requiring 5-30Vdc auxiliary supply at 20mA maximum.

A pulse with a DC offset can also be accommodated by adjusting the ‘ZERO’ adjustment to trim out the DC offset. The output pulse amplitude is adjustable via the 15-turn internal potentiometer that allows exact pulse voltage levels to be set. The module output is indicated by a front mounted L.E.D. which provides clear indication of module function and frequency output. The BPLR255 provides galvanic isolation up to 1500Vdc between input and the combined output and supply circuitry. RF and power transient protections are standard as it is with all BASI modules. Power supply variations from 63Vdc down to 12Vdc are available
