The GE IS420YAICS1B is an Analog I/O Module part of the Mark VIeS Series, designed for GE's distributed control systems. Serving as a critical interface between 1-2 I/O Ethernet networks and analog terminal boards, it integrates a shared Mark VIeS Safety processor board (BPPC) and a dedicated analog acquisition board.

• Analog Signal Handling: 10 analog inputs (8 configurable as 5V/10V or 4-20mA, 2 as 1mA or 0-20mA) with dual 0-20mA current loop outputs
• High Precision: 16-bit ADC resolution for 0.1% full-scale accuracy
• Connectivity: Dual RJ45 Ethernet ports, 3-pin 28VDC power input, and DC-37 pin connector with soft-start capability for hot-plugging
• Redundancy Support: Compatible with simplex or Triple Modular Redundant (TMR) configurations
• Noise Suppression: Hardware filters and adjustable software low-pass filters with 60dB AC common-mode rejection at 60Hz
• Robust Design: Operates in -40 to 158°F (-40 to 70°C) with power-up self-tests and continuous monitoring
• Compatibility: Works with TBAISIC/STAIS#A terminal boards and ControlST V06.01+ software
