Description
The AH115 is an eight-channel high-level analogue-input module originally for ALSPA CE2000 or CE3000. Its common-point inputs accept 0-5 V, 1-5 V or 0-10 V signals and 0-20 mA or 4-20 mA transmitters. The module can power loop transmitters and galvanically isolates the process inputs from the controller electronics and earth.
All eight measurements are acquired every 50 ms. Voltage inputs provide 12-bit equivalent resolution and ≤0.1% full-scale accuracy under reference conditions; current inputs provide 11-bit resolution and ≤0.15% accuracy. Internal zero and full-scale reference channels, configurable digital filtering and diagnostics detect process-supply loss, applicable open circuits, excessive gradients, out-of-range measurements, internal faults and communication errors.
Please check compatibility with the installed hardware and system configuration before ordering.
