What kind of I/O is available on the AC890?

How many analog inputs are on an AC890?
A. The AC890 has 4 configurable analog inputs, rated for -15VDC to +30VDC. The Analog Inputs can be configured in software for ranges of 0-10V, ±10V, 0-20mA or 4-20mA. All analog inputs have 12-bit resolution, (plus sign bit). The inputs are scanned approximately every 5 milliseconds. One selected input can be scanned every 1 millisecond.

How many analog outputs are on an AC890?
A.The AC890 has 2 configurable analog outputs with ranges of 0-10V or ±10V. The outputs are scanned approximately every 5 milliseconds. The analog outputs have 12-bit resolution (plus sign bit).

How many digital inputs are on an AC890?
A.The AC890 has 9 configurable digital inputs, all rated at +24VDC. The inputs are sampled approximately every 1 millisecond.

How many digital outputs are on an AC890?
A.The AC890 has three configurable digital outputs. Two are current sourcing outputs, DINOUT1 and DINOUT2 rated at 24V. The maximum output of all 24V sourced outputs is 160mA (i.e. iDINOUT1 + iDINOUT2 + i24V USER < 160mA) The third is a pair of volt-free relay contacts, DOUT3A and DOUT 3B rated at 24V SELV with a resistive load of 1A.
