FAQ – (10 Questions & Answers)

Q1: What is the primary role of the IS220PAICH2A?
A1: Its main role is to serve as an analog input/output interface module, connecting analog process signals to the control system’s Ethernet I/O network.

Q2: How many analog input channels does it support?
A2: It supports ten analog input channels—eight configurable for voltage or current loop, and two for special current ranges.

Q3: How many analog outputs are available on this module?
A3: There are two current‐loop analog outputs provided, each in the 0-20 mA range (with first output optionally up to 200 mA in some configs).

Q4: What are the physical size and weight of the module?
A4: The module is approximately 170 mm long, 100 mm wide and 35 mm high, and weighs around 0.72 kg (720 g).

Q5: What operating temperature range does the module support?
A5: It supports an operating range from about –30 °C to +65 °C, suitable for many industrial environments.

Q6: What kind of network interface does the module use?
A6: It uses dual Ethernet RJ-45 ports for connection to the I/O network, plus a DC-37 connector to link to the terminal board.

Q7: Can this module be used when upgrading older analog I/O systems?
A7: Yes—it is well suited for upgrade or retrofit projects where analog I/O density needs to be increased with minimal changes to infrastructure.

Q8: Does this analog I/O module support diagnostic indicators?
A8: Yes, it includes diagnostic LED indicators for module status, communications and fault detection, facilitating maintenance.

Q9: Is the module compatible with the Mark VIe I/O rack architecture?
A9: Yes, it is designed specifically for the Mark VIe I/O rack series and is compatible with other IS220 family modules.

Q10: What are the benefits of using this module in a control system?
A10: Benefits include flexible analog signal support, high reliability, compact size, modular plug-in format, network redundancy, and compatibility with high-performance industrial control systems.
