Input Specifications

The 170-AAI-140-00 features 16 analog input channels, each of which is single-ended. It supports input types, including ±10 V, ±5 V, and 4-20 mA signals. The module offers a 12-bit resolution with a sign for voltage inputs and maintains a full 16-bit signed data format. The input resistance is greater than 2200 kOhm for voltage signals and less than 0.25 Ohm for current signals, ensuring accurate and reliable measurements. Additionally, a low-pass input filter of 10 kHz is integrated to reduce noise and provide stable readings.

Accuracy and Performance

This analog input base provides exceptional measurement accuracy, with an absolute accuracy error of ±0.15% of full scale at 77°F (25°C) for ±10 V and ±5 V inputs and ±0.25% of full scale for 4-20 mA. Even under extreme temperatures, such as 140°F (60°C), the accuracy is maintained at ±0.25% of full scale for voltage inputs and ±0.45% of full scale for current inputs. The device features a temperature drift of 30 ppm/°C for voltage signals and 60 ppm/°C for current signals, ensuring minimal deviation over a wide range of operating conditions. The update time is ≤ 25 ms, providing timely and efficient data acquisition for real-time monitoring and control applications.

Electrical Characteristics and Protection

The 170-AAI-140-00 has comprehensive electrical protection features to ensure safe and reliable operation. It offers 1780 V AC isolation between channels and ground for one minute and 500 V isolation between supply and ground for one minute, which protects the device and connected components from electrical faults. The base module also includes reverse polarity protection and an internal 2 A slow-blow protection mechanism to safeguard against electrical mishaps. Additionally, it has a 500 mA fast-blow fuse rating for added security. The permissible standard mode voltage is up to 100 V DC or 250 V AC between channels and ground, making it suitable for various industrial settings.
