How many analog inputs are on an AC890?
- 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?
- 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?
- 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?
- 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.
