About the HE800ADC020
HE800ADC020 is an HE800 Analog Input Module manufactured by Horner APG. This module has 2 input channels. The converter type is Successive Approximation. The conversion time is set by the PLC scan time. The additional error for temperatures other than 25°C is 0.005% / °C. This module weighs 9 oz and has a resolution of 12-bit. The input ranges (including over-range) are 0-20.47 mA and ± 20.47 mA. The maximum error at 25°C is 0.05% of the full scale. The input impedance is 100 Ohm < 12 VDC, clamped at 12 VDC, 35 mA max. Continuous. The required steady state power is 0.09 W (4.1 mA at 24 VDC), and the required inrush power is negligible. The maximum overcurrent is 30 mA. This module does not have external power supply.
The module must be configured. Selecting the I/O Map tab provides information about the I/O registers, which are assigned to a specific SmartStack Module and where the module is located in the point map. The I/O Map is determined by the model number and location within the SmartStack.The input conversion factor for this module is Data = Input Current (mA) / Conversion Factor. When installing this module, remove power from the OCS controller, CAN port, and any peripheral equipment connected to this local system before adding or replacing this or any module. Only use shielded, twisted-pair wire to wire this module to the controller. Shields may be terminated at the module terminal strip. Shields should be tied directly to the ground block with the panel in severe applications. The wire type used should be Belden 8917, 16 AWG or larger.
