Input System Specifications
Aux Systems There are 6 Aux input systems that allow digital or analog (0-
1.0VDC, 0-5.0VDC, or 4-20mA) configuration. In addition, four
of the Aux systems can be configured as temperature systems see
Temperature Systems Specs - page 15.
Aux System Type Digital Analog
Range dry contact open/close 0 -1.0 VDC, 0-5.0 VDC, or 4-20mA
Accuracy n/a 0-1.0VDC: ± 3% ± 10 mV
0-5.0VDC: ± 3% ±15 mV
4-20 mA: ± 3% ±100μA
Resolution n/a user selectable (0), (0 .0), or (0.00)
DO Systems There are up to 4 independent DO systems. Each DO system has
2 control ranges, 2 control ranges, and high and low alarming.
