    MANUAL

Model JH377 is a pulse in, pulse out logic converter. Its input accepts 5 volt (TTL-compatible) or open-collector logic pulses (jumper selectable). The output, also jumper selectable, produces either 5 volt or open-collector output pulses in response. DC input coupling (no capacitor) permits operation down to zero Hz. For low level input such as tachometer pickups see our companion product, Model JH376.

Two channels are included in the 0.7 inch (17.8mm) wide enclosure, providing densities of almost 3 channels per inch. DC power may be anywhere between 7 and 24 volts. A green LED indicates power. Model JH377 does not provide input, output or power isolation.
