CAMAC - 3471 24-bit Isolated Input Gate View Datasheet Request Ordering Information     ABOUT 3471 The Model 3471 is a single-width CAMAC module providing 24 individually isolated contact sense circuits. The sense circuit detects the presence or absence of voltage at its terminals and is suitable for sensing such remote process contact closures as limit switches, machine tool relay contacts, pressure switches, manual switches, and mercury-wetted contacts. Four voltage options are available: 12 VDC, 24 VDC, 48 VDC, and 120 VAC. Input isolation is achieved by using LED/phototransistor optical isolators. Each circuit is a floating two-wire circuit with common-mode voltage isolation greater than 500 volts. Each option has 24 circuits with identical input voltage ratings, and the switching threshold is approximately one half the rated input voltage. Each input circuit draws more than five but less than ten milliamperes. Each input is conditioned by filtering after the optical isolator. The filtertime constant is 100 milliseconds. Other time constant options are availableby special order.
