GE IS220PCLAH1A Core Analog I/O Module

Model: IS220PCLAH1A

Pressure/Level Range: Factory-configurable from 0-1 bar up to 0-100 bar (or equivalent 0-10 m WC to 0-100 m WC), zero/span adjustable ±10 %.

Set-Points: Two independent cams for “Alert” and “Danger,” hysteresis adjustable 1-10 % of span.

Switch Outputs: Two SPDT gold-plated microswitches, rated 0.5 A @ 125 VAC / 1 A @ 30 V DC.

Analog Output (optional): Loop-powered 4-20 mA proportional to process value (requires loop-powered option).

Intrinsic Safety: Built-in Ex ia IIC barrier for Zone 0/1; certified ATEX II 1 G Ex ia IIC T4…T6 Ga, IECEx, FM Class I Div 1 Groups A-D.

Process Connection: ¼″ NPT female, 316 SS diaphragm (Hastelloy C optional); wetted parts 316 SS.

Temperature: Ambient -40 °C to +85 °C; process -40 °C to +120 °C.

Enclosure: IP66 / NEMA 4X die-cast aluminum with epoxy finish.

Approvals: SIL 2 capable per IEC 61508.

Product function

GE IS220PCLAH1A Dual-Setpoint Alarms: Provides two discrete trip levels (“Alert” and “Danger”) via mechanical microswitches for pre-warning and safety shutdown.

Continuous Monitoring (optional): The 4-20 mA loop output delivers real-time process value to DCS/PLC for trending or control.

Intrinsic Safety: Onboard barrier allows direct installation in Zone 0/1 without external isolators.

Field-Adjustable: Front-accessible cams and dial permit rapid zero, span, and hysteresis tuning without special tools.

High Reliability: Gold-plated contacts and rugged diaphragm ensure long service life even under frequent cycling.

Core supporting modules

GE IS220PCLAH1A External Junction Box (JB-IS): Provides cable entry and cable gland sealing compliant with hazardous-area ratings.

Loop Power Supply / Barrier Unit (BIC-IS): For installations requiring 4-20 mA analog output, ensures safe energy levels downstream.

GE IS220PCLAH1A Mounting Manifold (MNI-P): 316 SS flange-mount adapter for point-of-use installation in pipe or vessel lines.

Local Indicator Module (LIM-A): Field-mount display providing local readout of process value and alarm states.

Extension components

GE IS220PCLAH1A Core Analog I/O Module Remote Calibration Kit (RCK-S): Portable dead-weight or pressure-generator kit enabling on-site verification and calibration of set-points.

Cable Assemblies (CAB-IS): Pre-wired, shielded cable sets with M12 quick-disconnect connectors for fast field replacement.

Diaphragm Seal Assemblies (DSA-H): Fill-fluid sealed extension assemblies for high-temperature or corrosive media, maintaining intrinsic safety.

Explosion-Proof Conduit Fittings (XP-CON): Certified fittings to maintain enclosure integrity on conduit runs in Zone 0/1.

Software support

Configuration Utility (GE-Config Tool): Windows-based application for reading device identity and verifying barrier health via the optional digital interface.

Asset Management System (GE AMS Suite): Integrates analog loop data for historical trending, alarm analytics, and predictive maintenance dashboards.

HART Communicator (optional): If paired with a HART-enabled barrier, allows digital access to device diagnostics and calibration parameters.

FieldMate Mobile App: Bluetooth interface (via optional BT adapter) for tablet-based commissioning and health checks in the field.
