Multimeter

• 20 channels of analog input (w/automatic CJC) for general-purpose measurement.

• 16 channels of digital output.

• Event counter/totalizer can monitor and control system components, such as

fixturing, limit switches, pass/fail indicators, external voltage sources, loads, door

closures, revolutions, etc., while performing mixed signal measurement.

• 300V, 1A capacity; 60W, 125VA maximum.

• Configurable as two independent banks of multiplexers.

• Two analog outputs (±12V, 5mA).

• Relay closures stored in on-board memory.
