2-CHANNEL MAG COIL PULSE AMPLIFIER
For Tachometer & Turbine Meter Applications
Model JH376 is a compact, economical pulse amplifier for tachometers, turbine flowmeters and similar magnetic coil pickups. Input pulses are amplified and converted to either open-collector or logic-level output pulses, depending on your application. DC input coupling (no capacitor) permits operation down to zero Hz. Sensitivity adjustments, built-in hysteresis and input filtering minimize interference from noise pickup. Specifically designed for magnetic-coil pickups, the JH376 generally will not respond to TTL or other positive-only input pulses. For such applications see our companion product, Model JH377.
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. Because it is intended primarily for use with inherently-isolated magnetic pickups, no isolation is provided.
Model JH376 snaps onto 35mm DIN rail. Connections are made to the terminals (as marked on case).
Connections to the 8 terminals are:
B: Output 1.
D: Output 2.
E: Input 2.
G: Input 1.
