PRODUCT INFORMATION
Product Overview
The ABB 70AI01A is a four-channel analog input module designed for Procontrol P13/P14 systems. This module acquires standard voltage and current process control signals. It supports bipolar ±10 VDC inputs alongside ±20 mA and 4–20 mA current ranges. Internal processing utilizes a single multiplexed 16-bit successive approximation converter. The architecture samples input channels at an acquisition rate of 2500 Hz.
The module transmits digitized field data to the P13 local bus with 15-bit resolution. Channel conversion and bus transmission update across all four channels within 5 milliseconds. It assigns four consecutive local bus addresses within the normal or special address space. Engineers configure the unit via a front-panel RS-232 port using an onboard EEPROM. Power is supplied through the P13 rack backplane between +19.5 VDC and +30 VDC.
