GE K116LSIGZ2PMR
Product Name: GE K116LSIGZ2PMR — MicroVersa PM Trip Unit / 16-Channel Relay Output Module
Overview: The K116LSIGZ2PMR is a General Electric protective trip module belonging to the MicroVersa PM (Low Voltage) family, rated for 1600 A applications and compatible with P427 & WavePro low-voltage systems. Supplier catalogs also identify this part number as a K-Series 16-channel relay output module for GE Fanuc PLC systems. Source documents present both identities; the MicroVersa PM trip unit classification is reflected in the original catalog reference.

Key Features:
- 16 independent relay outputs with 2 A/point drive capability
- Supports both AC 240 V and DC 125 V load voltages
- Group isolation for interference-free channel operation
- Per-channel LED status indicators
- Compatible with most NPN-type proximity sensors when used as a digital input module (variant dependent)
Application Scenarios: Low-voltage circuit breaker protection and trip control (P427 & WavePro systems); actuator driving in small-to-medium PLC systems — plastic machinery, printing equipment, textile machinery, mining equipment.
Installation & Usage Precautions:
- Inductive loads MUST be fitted with flyback protection (diode or RC snubber)
- Never exceed the 2 A per-point rated current
- Confirm DIN rail clip is locked before energizing
- For digital input variant usage: unused input channels must be tied to a fixed level (high or low) — floating inputs are prohibited
- Disconnect external loads during extended idle periods
