Analog and Discrete Input/Output
Analog inputs can be either current or voltage. High common mode (200 Volts) amplifiers are
utilized. Each input has a separate input amplifier. Also, each two wire transmitter input (4-20mA)
is provided with a separate internal 24 volt regulator. Analog outputs source up to 20 milliamperes
to the user’s receiver (load).
Most discrete inputs are opto-isolated (refer to specifications). The sample rate resolution of one
millisecond provides for first out sequence of events capability. Three of these inputs can be
