New pulse amplifiers are for remote dc-powered environments. They operate -40° to +80°C. with supply voltages from 7 to 24-v dc. Neither is isolated: input, output, and power commons are internally connected.
JH376 is a compact DIN-rail mount device specifically for use with magnetic-coil pickups. Originally used for tachometers measuring speed of rotating drilling equipment, it is also well suited for turbine flowmeters.
JH377 is a two-channel Logic Pulse Converter that accepts contact closure or open-collector inputs. It converts them to 5-v logic pulses on flowmeters or tachometers having contact-closure outputs.
