GE IS420YAICS1B Analog I/O Module

IS420YAICS1B GE Mark VIeS Analog I/O Module

Product Introduction

The IS420YAICS1B belongs to the GE Mark VIeS series. This Analog I/O Module connects one or two I/O Ethernet networks to an analog terminal board. It includes a BPPC processor board and a dedicated acquisition board. You can use this IS420YAICS1B in simplex or TMR configurations. Its compact design fits harsh industrial environments.

Technical Specifications

The IS420YAICS1B offers ten analog inputs. The first eight inputs are configurable as 5V, 10V, or 4-20 mA current loops. The last two inputs support 1 mA or 0-20 mA signals. An onboard 16-bit ADC ensures precise conversion. Accuracy reaches 0.1% of full scale.

For noise rejection, this module uses hardware filters at 500 rad/s. Additionally, a software filter with cutoff options (0.75, 1.5, 3, 6, 12 Hz) is adjustable. Common mode rejection is 60 dB at 60 Hz. This performance guarantees clean data even with ±5V common mode voltage.

Power consumption is only 5.3 W typical. The IS420YAICS1B requires 28 V dc via a 3-pin power connector. Two RJ-45 ports (ENET1 and ENET2) provide network redundancy. A DC-37 pin connector links to the terminal board. LED indicators show real-time status for troubleshooting.

Mechanical and Environmental Data

This module operates within -40 to 158°F (-40 to 70°C). Its dimensions are H 3.25 in x W 1.65 in x D 4.78 in. The unit is manufactured in the USA. It uses a BPPC processor board. Firmware requirement is V05.01 or later. ControlST Software Suite must be V06.01 or later.

Installation Guidelines

First, securely mount the selected terminal board (TBAISIC or STAIS#A). Next, insert one simplex IS420YAICS1B or three TMR packs directly into the terminal board connectors. Then, use the threaded studs next to the Ethernet ports to lock the pack in place. Ensure no right-angle force applies to the DC-37 connector.

After mechanical fixing, connect one or two Ethernet cables. The pack works with either ENET1 or ENET2. For dual connections, connect ENET1 to the R controller network. Finally, plug in the 28 V dc power connector. The IS420YAICS1B includes soft-start capability, so you can connect power without disconnecting the cable.

Compatibility and Redundancy

This I/O pack works only with TMR or simplex applications. In TMR mode, you must use three identical packs. Do not mix IS420YAICS1B with IS420YAICS1A versions on the same terminal board. The pack supports firmware V05.01 and later. It also runs on ControlST V06.01 and later.

Diagnostics and Self-Tests

The IS420YAICS1B performs power-up self-tests. These checks include flash memory, RAM, processor hardware, and Ethernet ports. Moreover, it continuously monitors internal power supplies. This diagnostic ability ensures reliable operation in critical turbine control systems.

Why Choose the IS420YAICS1B

This module combines precision, connectivity, and ruggedness. Its dual current loop outputs (0-20 mA) interface easily with other devices. The three-pin power input guarantees stable performance. Additionally, the DC-37 connector simplifies wiring. For wind, gas, or steam turbine control, the IS420YAICS1B is a trusted choice.

Frequently Asked Questions (FAQ)

1. Can I use the IS420YAICS1B with ControlST V05.00?
No. The IS420YAICS1B requires ControlST V06.01 or later. Firmware must be V05.01 or above.

2. Is this module hot-swappable?
Yes. The soft-start circuit controls inrush current. You can connect or disconnect power without shutting down the system.

3. What terminal boards work with the IS420YAICS1B?
It works with TBAISIC and STAIS#A terminal boards. Do not use it with other terminal types.

4. How do I configure the analog input types?
Use ToolboxST software. Assign each of the first eight inputs as 5V, 10V, or 4-20 mA. The last two inputs are set to 1 mA or 0-20 mA.

5. What happens if I mix YAICS1A and YAICS1B packs on a TMR set?
The system will not function correctly. All three packs in a TMR set must be the same version. Mixing causes compatibility errors.
