Frequently Asked Questions

Can I mix voltage and current inputs on the same IC695ALG616 module?
Yes, each of the 16 channels is independently configurable for either voltage or current input through software settings in Proficy Machine Edition. This flexibility allows connection of mixed sensor types (e.g., 4-20mA pressure transmitters and 0-10V temperature sensors) on a single module without external signal conditioning.

What maximum cable distance is supported for analog signals?
Voltage inputs: up to 300 meters (1000 feet) using shielded twisted-pair cable with proper grounding. Current inputs: up to 750 meters (2500 feet) due to superior noise immunity of current loops. For longer distances, consider using 4-20mA transmitters or remote I/O solutions.

Does the IC695ALG616 provide power for field transmitters?
The module supplies internal loop power for 4-20mA two-wire transmitters, eliminating the need for external power supplies in many applications. Maximum loop resistance is 600Ω at 24VDC. Voltage-output sensors require separate power sources.

How do I configure input filtering to reduce noise?
Proficy Machine Edition software provides adjustable digital filtering with time constants from 0 to 10 seconds. For applications with high electrical noise, enable the 60Hz notch filter and increase the integration time. Hardware RC filters are not required for most installations.

Is this module compatible with legacy Series 90-30 systems?
No, the IC695ALG616 is designed exclusively for RX3i PACSystems and is not backward-compatible with Series 90-30 or 90-70 platforms. For Series 90-30 applications, use the IC693ALG220 or IC693ALG222 analog input modules.

What diagnostic capabilities help troubleshoot sensor problems?
The module provides channel-level diagnostics including open-circuit detection, over-range/under-range alarms, and wire-break detection for current inputs. Diagnostic status is accessible through CPU fault tables and can trigger alarms or email notifications via configured logic.
