Pulse Transmitter BPRM180

The BPRM180 converts slow speed pulse or frequency signals to an isolated process signal

Description

The BPRM180 converts slow speed pulse or frequency signals to an isolated process signal. The BPRM180 can accommodate pulse rates of 1 pulse per hour with a response time that is equal to the pulse rate. Maximum input is 100 p/sec. A pulse via the input trigger circuit starts a time count, which is terminated and restarted, on the next pulse. The period is determined and scaled over the range from the nominated upper and lower frequencies. Frequencies above the full scale being considered the same as the full scale frequency, and those below the zero scale frequency considered the same as the zero scale frequency. Thus the analogue output varies linearly over the range from the lower frequency (“0” scale) to the upper frequency (full scale). The output accuracy is derived from the inherent characteristics of an 8-bit D/A converter (typically 0.4%). The calibration parameters are factory programmed. RF and power transients protection are also standard aswith all BASI modules. Various power supply choices are available varying from 240Vac down to 8Vdc, all provide power isolation.
