ADAM-5017H 8-channel high speed analog input
module
The ADAM-5017H is a 12-bit plus sign bit, 8-channel analog differen-
tial input module that provides programmable input ranges on each
channel. It accepts millivolt inputs (± 500 mV, 0-500 mV), voltage
inputs (±1 V, 0-1 V, ±2.5 V, 0-2.5 V, ±5 V, 0-5 V, ±10 V and 0-10 V) and
current inputs (0-20 mA and 4-20 mA; requires a 125 ohms resistor).
The module provides data to the host microprocessor in engineering
units (mV, V or mA) or two’s complement format. Its sampling rate
depends on the data format received: up to 1,000 Hz (total) in two’s
complement or 600 Hz (total) in engineering units. Space is reserved for
125-ohm, 0.1%, 10 ppm resistors (See Figure 4-10). Each input channel
has 3000 V
DC
of optical isolation between the outside analog input line
and the module, protecting the module and peripherals from high input
line voltages. Additionally, the module uses analog multiplexers with
active overvoltage protection. The active protection circuitry assures
that signal fidelity is maintained even under fault conditions that
would destroy other multiplexers. The analog inputs can withstand a
constant 70 Vp-p input with ±15 V supplies.
