Series C76

Up to 1 Amp, 250 Vrms AC Input, DC Input, AC Output.

The C76 Series Solid State Computer Input/Out-put Modules are designed expressly for application in computerized control systems where reliable noise-free interface of switching is required to isolate computer logic elements from high conducted noise encountered in industrial environments. Sensitive logic circuitry is kept noise-free by means of optical isolation between logic and power lines. Output modules allow either TTL or CMOS level signals to control the switching of power to high voltage and high current loads. Hysteresis at the input significantly increases the noise margin when used in the CMOS input mode, preventing false triggering in noisy environments. Input modules convert the presence or absence of load level voltages from pressure, flow, temperature and other transducers, limit switches, solenoids or relays to “clean” low level logic signals for computer input.  An ENABLE function maintains the module’s output in an “open” state until the ENABLE terminal is brought up to the bias supply level.
